We propose a single piece optical fiber-based two-dimensional scanning hand-held probe suitable for three-dimensional optical coherence tomography. The probe consists of only a single piece of optical fiber loaded with a bead of ferromagnetic material, which acts as a vibrating cantilever. The fiber cantilever is two dimensionally actuated with a single miniaturized solenoid. For effective beam focusing, a fiber lens is formed at the end of the fiber. The inductance and input current of the solenoid were 100 mu H and 216 mA, respectively. The iron-bead on the fiber is located at the off-axis of solenoid for two-dimensional scanning. Then, by modulating the input current to the solenoid, it was possible to mechanically oscillate the fiber cantilever in an elliptically spiral pattern. With the proposed probe, 2-dimensional scanning could be experimentally achieved in a rate of 4 s/vortex across a scanning area of approximately 30 mm(2), which could be controlled with the length of the fiber or/and the weight of the iron-bead. Three-dimensional tomographic image of a coin was successfully obtained with the spectral domain optical coherence tomography equipped with the proposed scanner. It is expected that the scheme of 2-dimentional scanning with a single actuator might be useful in various real-time imaging applications including OCT owing to the advantages of low cost, low power consumption, simple fabrication process and versatile design.

Atomic Force Microscope (AFM) imaging, due to the scanning method of recording, requires significant recording time for examination of wide sample area. In contrast, digital holographic microscopy (DHM), owing to the wide-field method, allows recording of the hologram in very fast rate which could be numerically analyzed to reveal surface of the sample with axial resolution at the nanometer scale. However, DHM yields quantitative phase properties of the sample, and therefore sensitive to changes in refractive index along with physical thickness. Therefore, to accurately determine the refractive index map, it is imperative to estimate the physical thickness map of the sample. This was achieved by AFM imaging. Further, since the transverse resolution of DHM is limited by diffraction limit, co-registration of AFM image provided higher transverse resolution at nanometer scale. The interference of the AFM probe was observed to be minimal during simultaneous AFM and DHM recording due to the transparent nature and bent configuration of the optical fiber based AFM cantilever. Integration of DHM and AFM led to realization of a powerful platform for nanoscale imaging. The integrated AFM-DHM system was built on an inverted fluorescence microscope to enable fluorescence imaging of the sample. The integrated system was employed to analyze fluorescent polystyrene microspheres, two-photon polymerized microstructures and red blood cells.

The images obtained from confocal imaging systems present less resolution than the theoretical limit due to imperfection of the optical components and their arrangement. This imperfection deteriorates the wavefront and introduces aberrations to the optical system. Adaptive optics (AO) systems composed of a wavefront sensor (WFS) and a deformable mirror represent the most used solution to this problem. Such adaptive optics systems are expensive. In addition, in microscopy, WFSs cannot be used due to stray reflections in the system and high aberrations introduced by the specimen. For these reasons, sensor-less AO systems have been developed to control the deformable mirror (DM) using an optimization algorithm in an iterative manner. At each iteration, the algorithm produces a new set of voltage and sends it to the mirror so as to optimize its shape, in such a way, as to maximize the strength of the photodetector current in the imaging system. In this paper the results of the application of three optimization techniques in the sensor-less AO are compared. The three optimization techniques are simulated annealing (SA), genetic algorithm (GA) and particle swarm optimization (PSO). SA and GA have been previously implemented and PSO is explained in this paper.

In-vivo microscopic long term time-lapse studies require controlled imaging conditions to preserve sample viability. Therefore it is crucial to meet specific exposure conditions as these may limit the applicability of established techniques. In this work we demonstrate the use of third harmonic generation (THG) microscopy for long term time-lapse three-dimensional studies (4D) in living Caenorhabditis elegans embryos employing a 1550 nm femtosecond fiber laser. We take advantage of the fact that THG only requires the existence of interfaces to generate signal or a change in the refractive index or in the chi(3) nonlinear coefficient, therefore no markers are required. In addition, by using this wavelength the emitted THG signal is generated at visible wavelengths (516 nm) enabling the use of standard collection optics and detectors operating near their maximum efficiency. This enables the reduction of the incident light intensity at the sample plane allowing to image the sample for several hours. THG signal is obtained through all embryo development stages, providing different tissue/structure information. By means of control samples, we demonstrate that the expected water absorption at this wavelength does not severely compromise sample viability. Certainly, this technique reduces the complexity of sample preparation (i.e. genetic modification) required by established linear and nonlinear fluorescence based techniques. We demonstrate the non-invasiveness, reduced specimen interference, and strong potential of this particular wavelength to be used to perform long-term 4D recordings.

Little is understood about the detailed micromechanical properties of lung in vivo. Attempts to improve imaging are hampered by heterogeneity of the tissue. One common ex vivo technique is optical coherence tomography (OCT). Simulated OCT with a Finite-Difference Time-Domain (FDTD) computer model elucidates the relationship between captured images and the physical geometry of the lung. Parallel computation and improved processing power make accurate coherent imaging models feasible. A previous FDTD model of pulsed laser wave propagation in the lung produced images that displayed many of the properties of experimental images. The model was improved with the addition of elastin and increased computational volume. Elastin plays an important role in the simulation because the combination of its fibrous structure and high index of refraction acts as an excellent scatterer of light. This strong scattering increases the signal reported by the simulated OCT scan in areas where elastin is most abundant, improving visualization of the structure as more light is reflected back from the heterogeneous elastin network. However, scattering by elastin decreases the depth of penetration and leads to images that are more difficult to interpret. Gaining a better understanding of how lung structures affect light propagation will lead to improved signal processing, instrumentation, and the development of new probing techniques. This image modeling technique can also be applied to other imaging modalities such as confocal and other laser scanning methods.

Confocal reflectance microscopy may enable screening and diagnosis of skin cancers noninvasively and in real-time, as an adjunct to biopsy and pathology. Current confocal point-scanning systems are large, complex, and expensive. A confocal line-scanning microscope, utilizing a of linear array detector can be simpler, smaller, less expensive, and may accelerate the translation of confocal microscopy in clinical and surgical dermatology. A line scanner may be implemented with a divided-pupil, half used for transmission and half for detection, or with a full-pupil using a beamsplitter. The premise is that a confocal line-scanner with either a divided-pupil or a full-pupil will provide high resolution and optical sectioning that would be competitive to that of the standard confocal point-scanner. We have developed a confocal line-scanner that combines both divided-pupil and full-pupil configurations. This combined-pupil prototype is being evaluated to determine the advantages and limitations of each configuration for imaging skin, and comparison of performance to that of commercially available standard confocal point-scanning microscopes. With the combined configuration, experimental evaluation of line spread functions (LSFs), contrast, signal-to-noise ratio, and imaging performance is in progress under identical optical and skin conditions. Experimental comparisons between divided-pupil and full-pupil LSFs will be used to determine imaging performance. Both results will be compared to theoretical calculations using our previously reported Fourier analysis model and to the confocal point spread function (PSF). These results may lead to a simpler class of confocal reflectance scanning microscopes for clinical and surgical dermatology.

The examination of the dermis/epidermis junction (DEJ) is clinically important for skin cancer diagnosis. Reflectance confocal microscopy (RCM) is an emerging tool for detection of skin cancers in vivo. However, visual localization of the DEJ in RCM images, with high accuracy and repeatability, is challenging, especially in fair skin, due to low contrast, heterogeneous structure and high inter-and intra-subject variability. We recently proposed a semi-automated algorithm to localize the DEJ in z-stacks of RCM images of fair skin, based on feature segmentation and classification. Here we extend the algorithm to dark skin. The extended algorithm first decides the skin type and then applies the appropriate DEJ localization method. In dark skin, strong backscatter from the pigment melanin causes the basal cells above the DEJ to appear with high contrast. To locate those high contrast regions, the algorithm operates on small tiles (regions) and finds the peaks of the smoothed average intensity depth profile of each tile. However, for some tiles, due to heterogeneity, multiple peaks in the depth profile exist and the strongest peak might not be the basal layer peak. To select the correct peak, basal cells are represented with a vector of texture features. The peak with most similar features to this feature vector is selected. The results show that the algorithm detected the skin types correctly for all 17 stacks tested (8 fair, 9 dark). The DEJ detection algorithm achieved an average distance from the ground truth DEJ surface of around 4.7 mu m for dark skin and around 7-14 mu m for fair skin.

High Dynamic Range (HDR) image sensors aim at having a dynamic over 120dB. Compared to classical architectures this is obtained at the cost of a higher transistor count, thus lower fill factor. Three dimensional integrated circuits (3D-IC) somehow change the constraints, photodiodes and electronics can be stacked on different layers, giving more processing powers without compromising the fill factor. In this paper, we propose an original architecture for a high dynamic 3D image sensor with data reduction obtained by local compression. HDR acquisition is based on a floating point coding shared by a group of pixel (macro-pixel), thus giving also a first level of compression. A second level of compression is performed by using a Discrete Cosine Transform (DCT). With this new concept a good image quality (PSNR of about 40 dB) and a high dynamic range (120 dB) are obtained within a pixel area of 5 mu mx5 mu m.

Stress-engineered optical elements show fascinating and potentially useful effects when placed at the pupil plane of an imaging system. When illuminated by a beam of spatially uniform polarization, a snapshot (single measurement) polarimetry method can be constructed. We expand upon this method to perform snapshot pupil polarimetry for spatially varying pupil polarization. We present the theory for snapshot non-uniform pupil polarization measurement using a stress-engineered optical element, as well as simulation results.
