The spatial point spread function is studied for two-photon fluorescence imaging in turbid media. Using a Monte Carlo based model the effects of tissue optical properties on the point spread function, fluorescence generation, and fluorescence collection are studied. The simulated results are compared to measured point spread functions at different depths within a scattering sample. Results indicate that the limiting factor in two-photon imaging is a loss of signal caused by scattering rather than a loss of resolution.

A major goal in neuroanatomy is to obtain precise information about the functional organization of neuronal assemblies and their interconnections. Therefore, the analysis of histological sections frequently requires high resolution images in combination with an overview about the structure. To overcome this conflict we have previously introduced a software for the automatic acquisition of multiple image stacks (3D-MISA) in confocal laser scanning microscopy. Here, we describe a Windows NT based software for fast and easy navigation through the multiple images stacks (MIS-browser), the visualization of individual channels and layers and the selection of user defined subregions. In addition, the MIS browser provides useful tools for the visualization and evaluation of the datavolume, as for instance brightness and contrast corrections of individual layers and channels. Moreover, it includes a maximum intensity projection, panning and zoom in/out functions within selected channels or focal planes (x/y) and tracking along the z-axis. The import module accepts any tiff-format and reconstructs the original image arrangement after the user has defined the sequence of images in x/y and z and the number of channels. The implemented export module allows storage of user defined subregions (new single image stacks) for further 3D-reconstruction and evaluation.

We have studied three-dimensional reconstruction methods to estimate the cell volume of astroglial cells in primary culture. The studies are based on fluorescence imaging and optical sectioning. An automated image-acquisition system was developed to collect two-dimensional microscopic images. images were reconstructed by the Linear Maximum a Posteriori method and the non-linear Maximum Likelihood Expectation Maximization (ML-EM) method. In addition, because of the high computational demand of the ML-EM algorithm, we have developed a fast variant of this method. 1) Advanced image analysis techniques were applied for accurate and automated cell volume determination. 2) The sensitivity and accuracy of the reconstruction methods were evaluated by using fluorescent micro-beads with known diameter. The algorithms were applied to fura-2-labeled astroglial cells in primary culture exposed to hypo- or hyper-osmotic stress. The results showed that the ML-EM reconstructed images are adequate for the determination of volume changes in cells or parts thereof.

Confocal fluorescence imaging is widely used, particularly for biological applications, and also notably in direct-view microscopes. Recent work has compared the use of coherent and incoherent illumination sources on the optical sectioning characteristics of fluorescence direct-view microscopes. However this detailed comparison has been done in theory. This paper adresses the experimental aspects of using coherent light sources in fluorescence imaging using a range of finite-sized, multiple-aperture arrays. The experimental difficulties of choosing a suitable uniform, flat, fluorescent plane with a high quantum efficiency are considered. Axial response curves obtained with a fluorescent laser dye sample are presented.

The basic procedure of spectral image analysis is mapping, i.e., generation of conventional images using specific spectral features from multidimensional data set. Commonly, it is based on decomposition of the original spectra into a sum of model spectra which are usually attributed to chemically/physically different components. However, the problem is complicated when the model spectra are not clearly definable or difficult and even impossible to obtain experimentally. Here we describe a method for estimating spectral models based on the elimination of physical meaningless solutions obtained by PCA (Principal Component Analysis). The method includes the following steps: segmentation of the original spectral image using a white-light image;generation of primary factors for each segmented region by MDF ( maximum distance factors) algorithm;extending the factor space to satisfy non-negative score requirements;generation of model limits by rotation of factor matrix in conditions of non-negative intensity values;calculation of the common model as intersection regions in the score space. The precision of the method depends on the spectral variations in the original data. When these variations are significant the models could be obtained precisely and then attributed to possible sample components. This method was validated in different research fields : to study the distribution of anticancer drugs in single living cells, to characterize phenolic species in wheat walls.

We have built an interference microscope that produces in real-time images of cross-section slices located at adjustable depths inside 3-D objects. The microscope is based on a Michelson-type polarization interferometer. A light emitting diode (LED), used as an optical source at lambda = 840 nm with short coherence length, provides optical sectioning ability with better than 10 mu m resolution in the depth dimension. By using high numerical aperture objective lenses (NA = 0.95), the depth resolution can be improved to better than 1 mu m, in good agreement with theory. images can be produced at the rate of 50 per second using a multiplexed lock-in detection and MMX assembler-optimized calculation routines. Cross-section images inside an onion and at different depths in a multilayer silicon integrated circuit are presented.

Evaluation of cell morphology by bright field microscopy is the pillar of histopathological diagnosis. The need for quantitative and objective parameters for diagnosis has given rise to the development of morphometric methods. The development of spectral imaging for biological and medical applications introduced both fields to large amounts of information extracted from a single image. Spectroscopic analysis is based on the ability of a stained histological specimen to absorb, reflect, or emit photons in ways characteristic to its interactions with specific dyes. Spectral information obtained from a histological specimen is stored in a cube whose appellate signifies the two spatial dimensions of a flat sample (x and y) and the third dimension, the spectrum representing the light intensity for every wavelength. The spectral information stored in the cube can be further processed by morphometric analysis and quantitative procedures. Such a procedure is spectral-similarity mapping (SSM), which enables the demarcation of areas occupied by the same type of material. SSM constructs new images of the specimen, revealing areas with similar stain-macromolecule characteristics and enhancing subcellular features. Spectral imaging combined with SSM reveals nuclear organization through the differentiation stages as well as in apoptotic and necrotic conditions and identifies specifically the nucleoli domains.

The simultaneous manipulation and observation of morphological features of single living cells along with the recording of functional changes related to cellular metabolism, interaction and communication in real time are of growing interest. With the advent of atomic force microscopy (AFM) structural studies of native cells became possible which in combination with adequate light microscopy give a much better resolution than light microscopy alone. However, the motion of the cell, the softness of the cell membrane and the two-dimensional growth of cells in culture limit applicability and resolution of this technique. A good mechanical fixation of living cells in a structure could be achieved by embedding cells into partially covered grooves produced in Si/SiO2. However, for additionally optical microscopy studies a transparent material is essential. In this study we present the fabrication of different transparent three-dimensional structures in a three-layer system (Si3N4, SiO2, Si3N4) on quartz specially sized for the trapping of living neural cells under physiological conditions. For the fabrication of the structures we utilized a combination of e-beam lithography (EBL), laser ablation, reactive ion beam etching (RIBE) and different wet etching techniques. The structures consist of a nano-net of Si3N4 covering a micro-cavity in SiO2 confining enough to prevent the cell body from escaping, but not so constraining that it hinders normal growth and development. Another type of presented structures consists of cavities which are connected by covered micro-channels, hence, an observation of cell-cell interactions is also possible. Advantages of these microstructures are the trapping of cells, the stabilization of the cell membrane and the precise placement of the cells for a multitude of biological investigations.

Confined arrays of biochemical probes deposited on a solid support surface (analytical microarray or "chip") provide an opportunity to analysis multiple reactions simultaneously. Microarrays are increasingly used in genetics, medicine and environment scanning as research and analytical instruments. A power of microarray technology comes from its parallelism which grows with array miniaturization, minimization of reagent volume per reaction site and reaction multiplexing. An optical detector of microarray signals should combine high sensitivity, spatial and spectral resolution. Additionally, low-cost and a high processing rate are needed to transfer microarray technology into biomedical practice. We designed an imager that provides confocal and complete spectrum detection of entire fluorescently-labeled microarray in parallel. imager uses microlens array, non-slit spectral decomposer, and high-sensitive detector (cooled CCD). Two imaging channels provide a simultaneous detection of localization, integrated and spectral intensities for each reaction site in microarray. A dimensional matching between microarray and imager's optics eliminates all in moving parts in instrumentation, enabling highly informative, fast and low-cost microarray detection. We report theory of confocal hyperspectral imaging with microlenses array and experimental data for implementation of developed imager to detect fluorescently labeled microarray with a density similar to 10(3) sites per cm(2).

Confocal photoluminescence imaging is an important tool in the investigation of recombination in semiconductors and in the characterisation of material growth. This characterisation is particularly important for II-VI wide band-gap semiconductors where the potential for blue-green lasers is being explored currently. To achieve room-temperature cw operation of these lasers over the multi-thousand hours necessary for commercialisation, extremely low defect densities are required. The confocal microscope is used in this work to image photoluminescence from II-VI materials to characterise the defect formation and propagation within the quantum well region of the material. This imaging approach permits the degradation to be monitored in real time and over a large area in samples with low defect densities. The additional advantages of this set-up over a conventional microscope are, of course, the higher lateral resolution and narrow depth of field associated with a confocal microscope. While considerable effort has been focused on the degradation in these II-VI semiconductors, we have recently observed that annealing can occur simultaneously in the same sample when the material is exposed to intense optical excitation. images of annealing and degradation of a range of II-VI samples will be presented to highlight these observations.
