    Abstract:

    A technique is presented to determine surface contours of 3-D objects by laser speckle interferometry. A double exposure specklegram is recorded by giving the object a small tilt between exposures. Surface contours are obtained by Fourier filtering of the specklegram.

    Confocal Fluorescence Microscopy

    Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
