Adaptive Optics for Wide-field microscopy

Adaptive Optics for Wide-field Microscopy

conference on Three-dimensional and multidimensional microscopy - image acquisition and processing XVIII

We report on recent developments in the use of adaptive optics (AO) in wide-field microscopy to remove both system and sample induced aberrations. We describe progress on using both a full AO system and image optimization techniques (wavefront sensorless AO). In the latter system the determination of the best mirror shape is found via two routes. In the first an optimization algorithm using a Simplex search pattern is used with an initial random set of mirror shapes. We then explore the use of specific Zernike terms as our starting basis set. In both cases the final optimization performance is not affected by the choice of optimization metric. We then describe an open loop AO system in which the equivalent of a laser guide star is used as the light source for the wavefront sensor.

We propose a new approach of in-line digital holographic microscopy (DHM) with the capability of enhancing the hologram acquisition rate together with improved reconstruction capability. The method is based on the recording of two interferograms of the same object at slightly different planes. The technique utilizes the full spatial bandwidth of the camera and do not require phase-shifting of the reference beam. Furthermore, we exploit the method of subtraction of average intensity of the entire hologram to suppress the zero-order diffracted wave. The twin image is eliminated by Fourier domain processing of the two recorded holograms. Experimental results of both amplitude and phase objects demonstrate the feasibility of this method. Since the two interferograms can be recorded simultaneously by using two CCD or CMOS sensors, this new in-line DHM technique has the potential applications in biomedical research for the visualization of rapid dynamic processes at cellular level.

This paper describes a novel approach to quantifying mitochondrial patterns which are typically described using the qualitative terms "diffuse" "aggregated" and are potentially key indicators for an oocyte's health and survival potential post-implantation. An oocyte was isolated in a confocal image and a coarse grid was superimposed upon it. The spatial spectrum was calculated and an aggregation factor was generated. A classifier for healthy cells was developed and verified. The aggregation factor showed a clear distinction between the healthy and unhealthy oocytes. The ultimate goal is to screen oocytes for viability preimplantation, thus improving the outcome of in vitro fertilization (IVF) treatments.

Oblique Plane microscopy (OPM) is a light sheet microscopy technique that combines oblique illumination with correction optics that tilt the focal plane of the collection system. OPM can be used to image conventionally mounted specimens on coverslips or tissue culture dishes and has low out-of-plane photobleaching and phototoxicity. No moving parts are required to achieve an optically sectioned image and so high speed optically sectioned imaging is possible. The first OPM results obtained using a high NA water immersion lens on a commercially available inverted microscope frame are presented, together with a measurement of the achievable optical resolution.

Cryogenic procedures are fundamental tools in modern biology, e. g. for conservation or purification of biological materials. The processes occurring in biological cells and tissues during freezing and thawing are subject to ongoing research. Optimization of cell survival rates demands the development and evaluation of exactly defined temperature profiles. 4D-DMD-microscopy is capable of imaging these highly dynamic processes with high spatial and temporal resolution, utilizing well established staining procedures for differentiating structures of interest.

This work describes improved methods and algorithms for implementing extended depth of field (EDF) microscopy through point spread function (PSF) engineering. It utilizes adaptive optics to create a test bed on which to evaluate new phase shapes for EDF. Being able to quickly and cheaply design novel PSFs is essential to overcome limitations of EDF that have prevented the technology from reaching mainstream use. Further improvement is made by reducing the noise normally seen in EDF images. Computational optics principles are used to first encode the noise with an identifiable pattern and a specially-tailored non-linear algorithm then removes the noise. This approach improves a microscope's imaging capabilities in photon-starved applications such as live-cell fluorescence and object tracking.

The effect of depth-induced spherical aberrations (SA) on structured illumination microscopy (SIM)(1) is investigated. SIM is a technique used in three-dimensional (3D) fluorescence microscopy to improve resolution in optical sections acquired from 3D specimens. A 3D depth-variant imaging model was developed to predict the intermediate SIM or grid images that are used by the SIM approach to compute improved optical sections. The model incorporates SA due to imaging depth within a sample when there is a refractive index (RI) mismatch between the average RI of the specimen and the RI of the immersion medium of the lens. The model was implemented using a stratum-based model approximation and multiple depth-variant point-spread functions (PSFs)(2). SIM optical sections were computed using the subtraction algorithm(1, 3) and simulated grid images that include SA predicted by our model. Simulations were performed for different imaging conditions by varying the grid frequency, the amount of SA and the level of noise added to the grid images. Simulated results demonstrate that SIM images are less accurate in the presence of SA, and confirm that the SIM approach is very sensitive to system noise resulting in a reduced SNR in the optically sectioned images.

We realized a real-time dual-mode standard/complex Fourier-domain optical coherence tomography (FD-OCT) system using graphics processing unit (GPU) accelerated 4D (3D+time) signal processing and visualization. For both standard and complex FD-OCT modes, the signal processing tasks were implemented on a dual-GPUs architecture that included lambda-to-k spectral re-sampling, fast Fourier transform (FFT), modified Hilbert transform, logarithmic-scaling, and volume rendering. The maximum A-scan processing speeds achieved are >3,000,000 line/s for the standard 1024-pixel-FD-OCT, and >500,000 line/s for the complex 1024-pixel-FD-OCT. Multiple volume-rendering of the same 3D data set were preformed and displayed with different view angles. The GPU-acceleration technique is highly cost-effective and can be easily integrated into most ultrahigh speed FD-OCT systems to overcome the 3D data processing and visualization bottlenecks.

Optical projection tomography (OPT) requires a large depth of field (DOF) of a low numerical aperture (NA) lens resulting in low resolution. However, DOF of a high NA objective can be extended by scanning the focal plane through the sample. This extended DOF image is called pseudoprojection, which is used by optical projection tomographic microscope (OPTM) for tomographic reconstruction. The advantage of OPTM is the acquisition of relatively high resolution and large depth of field concurrently. This method requires the working distance of the lens to be larger than the size of the sample, so proper lens should be chosen for samples of different sizes. In this paper, we imaged hematoxylin stained muntjac cells inside capillary tube with two different sizes. Two objective lenses with different NA are used for these two tubes. Experimental results show that resolution improves over 10 times in OPTM compared to conventional OPT, which make it possible for OPTM technique to resolve sub-cellular features for large samples. Therefore, OPTM can be used for 3D histological analysis of hematoxylin & eosin (H&E) stained biopsy specimen with sub-cellular resolution in the future.

Many interferometry-based quantitative phase contrast imaging techniques require the generation of a coherent reference wave, which results in a phase stability decrease and the demand for a precise adjustment of the intensity ratio between object and reference wave. Thus, investigations on a simplified digital holographic microscopy approach that avoids a separate reference wave were performed. Results from live cell investigations demonstrate the capability of the method for quantitative phase contrast imaging. In further experiments the modification of the intracellular refractive index distribution by osmotic stimulation was analyzed. Data from human pancreas tumor cells show that by choice of suitable buffer solutions live cell imaging with enhanced quantitative phase contrast is achieved.
