The errors can cause the serious loss of the performance of a precision machine system. In this paper, we propose the method of allocating the alignment tolerances of the components and apply this method to Confocal Scanning microscopy (CSM) to get the optimal tolerances. CSM uses confocal aperture, which blocks the out-of-focus information. Thus, it provides images with superior resolution and has unique property of optical sectioning. Recently, due to these properties, it has been widely used for measurement in biological field, medical science, material science and semiconductor industry. In general, tight tolerances are required to maintain the performance of a system, but a high cost of manufacturing and assembling is required to preserve the tight tolerances. The purpose of allocating the optimal tolerances is minimizing the cost while keeping the performance of the system. In the optimal problem, we set the performance requirements as constraints and maximized the tolerances. The Monte Carlo Method, a statistical simulation method, is used in tolerance analysis. Alignment tolerances of optical components of the confocal scanning microscopy are optimized, to minimize the cost and to maintain the observation performance of the microscopy. We can also apply this method to the other precision machine system.

Randomly selected pathology sections of lung tissue are used to correlate lung pathology with Computer Tomography (CT) images. The randomly selected pathology sections provide physicians with little freedom to thoroughly investigate specific areas of interest as identified via CT images. A Large image Microscope Array (LIMA) was designed to serially section and image entire organs for direct correlation between lung pathology and CT. The LIMA consists of a novel vibratome, capable of sectioning tissue down to a thickness of 40mum at specimen dimensions of 20cm by 30cm to a total depth of 30cm. A camera. and a stereomicroscope, mounted on a XYZ gantry above the vibratome is moved through an automated raster scan to capture the entire surface area of the tissue via many high magnification images. A custom software program was developed to automate all hardware components. The alignment and stitching of the images is achieved though custom C++ code in conjunction with the Insight Segmentation and Registration Toolkit (ITK). The resulting high magnification, high-resolution pathology images are registered with corresponding CT images. Through point-to-point correlation between the two imaging techniques a pathological and CT ground truth may be established.

Chondrocytes, obtained from testosterone treated human articular cartilage, were examined by a recently developed Multiple Beam Interference microscopy (MBIM) attached to a confocal set up, Video-enhanced differential interference microphotography and also by cinematography. In the MBIM, the intensity of the transmitted pattern is given by the Airy function which increases the contrast dramatically as the coefficient of the reflectance of the parallel plates increases. Moreover, in this configuration, the beam passes several times through a specific organelle and increases its optical path difference both because of the increase in the trajectory and refractive index (high density) of the organelle. The improved contrast enhances the resolving power of the system and makes visible several structural details of sub micron dimensions like nucleolus, retraction fibers, podia, etc. which are not possible to reveal with such a clarity by conventional techniques such as bright field, phase contrast or DIC. This technique permits to detect the oscillatory and rotational motions of unstained cilia for the first time. The frequency of oscillations was found to be 0.8 HZ. Keywords: Multiple Beam Interference Microscope, Chondrocytes Nucleolus and microfilaments, cilium and oscillatory & rotatory motion.

Recently surgery requires extensive support from imaging technologies in order to increase effectiveness and safety of operations. One of important tasks is to enhance visualisation of quasi-phase (transparent) 3D structures. Those structures are characterized by very low contrast. It makes differentiation of tissues in field of view very hard. For that reason the surgeon may be extremely uncertain during operation. This problem is connected with supporting operations of inner ear during which physician has to perform cuts at specific places of quasi-transparent vellums. Conventionally during such operations medical doctor views the operating field through stereoscopic microscope. In the paper we propose 3D visualization system based on Helmet Mounted Display. Two CCD cameras placed at the output of stereoscopic microscope perform acquisition of stereo pairs of images. The images are processed in real-time with the goal of enhancement of quasi-phase structures. The main task is to create an algorithm that is not sensitive to changes in intensity distribution. The disadvantages of existing algorithms are their lack of adaptation to occurring reflexes and shadows in field of view. The processed images from both left and right channels are overlaid on the actual images exported and displayed at LCD's of Helmet Mounted Display. A physician observes by EMD a stereoscopic image of operating field with indication of the regions of special interest. The authors present the hardware, procedures applied and initial results of inner ear structure visualization. Several problems connected with processing of stereo-pair images are discussed.

The application of conventional confocal microscopes with high numerical aperture (NA) to in vivo imaging is limited by the objectiveis large physical dimensions and short working distance. We are developing a confocal microscope that uses simple low NA lenses oriented in a dual axes configuration for miniaturization and in vivo imaging. This architecture achieves a long working distance, micron level axial resolution, and reduced noise from scattered light outside the focal volume. Combined with the novel method of post-objective scanning, this design can be scaled down to millimeter dimensions. We derive the dual axes response from diffraction theory, and construct two tabletop prototypes to demonstrate the performance of this approach. We collect images from freshly excised biopsy specimens of human esophagus and transgenic mouse cerebellum expressing GFP. With horizontal cross-sectional images, we achieve 1 to 2 mum resolution and collect reflectance and fluorescence images. With vertical cross-sectional images, we achieve 4 to 5 mum resolution, dynamic range of 70 dB, and tissue penetration over 1 mm. An instrument miniaturized with this configuration could be used for in vivo cellular and molecular imaging.

Different sub-cellular compartments and 2 organelles, such as cytosol, endoplasmic reticulum and mitochondria, are known to be differentially involved in Ca2+ homeostasis. It is thus of primary concern to develop imaging paradigms that permit to make out these diverse components. To this end, we have constructed a complete system that performs multi-functional imaging under software control. The main hardware components of this system are a piezoelectric actuator, used to set objective lens position, a fast-switching monochromator, used to select excitation wavelength, a beam splitter, used to separate emission wavelengths, and a I/O interface to control the hardware. For these demonstrative experiments, cultured HeLa cells were transfected with a Ca2+ sensitive fluorescent biosensor (cameleon) targeted to the mitochondria (mtCam), and also loaded with cytosolic Fura2. The main system clock was provided by the frame-valid signal (FVAL) of a cooled CCD camera that captured wide-field fluorescence images of the two probes. Excitation wavelength and objective lens position were rapidly set during silent periods between successive exposures, with a minimum inter-frame interval of 2 ms. Triplets of images were acquired at 340, 380 and 430 nm excitation wavelengths at each one of three adjacent focal planes, separated by 250 nm. Optical sectioning was enhanced off-line by applying a nearest-neighbor deconvolution algorithm based on a directly estimated point-spread function (PSF). To measure the PSF, image stacks of sub-resolution fluorescent beads, incorporated in the cell cytoplasm by electroporation, were acquired under identical imaging conditions. The different dynamics of cytosolic and mitochondrial Ca2+ signals evoked by histamine could be distinguished clearly, with sub-micron resolution. Other FRET-based probes capable of sensing different chemical modifications of the cellular environment can be integrated in this approach, which is intrinsically suitable for th

images of the microspheres are studied in three-dimensions by using the confocal and conventional scanning polarization microscopes. It is found that the polarization of the detected signals is mainly parallel to the initial polarization which is due to the high extinction coefficient of the confocal system. Arc pairs are observed at the edge of the microspheres with the conventional polarization microscope with a crossed analyzer. Theoretical analysis are given by using the vector field theory and the image formations of the two systems.

An approximate model for optical-sectioning microscopy describing depth-varying imaging is developed. The model incorporates changes in the point-spread function due to refractive index mismatch between the immersion medium and the specimen. which causes spherical aberration that worsens with increasing depth tinder the coverslip. Comparison of model predictions to measured images from a bead phantom shows that the approximate model captures the main features in the data. The model presented in this paper is the first step towards depth-variant image estimation for optical-sectioning microscopy. An expectation maximization algorithm for maximum-likelihood restoration based on this model is also presented.
