Optical characteristics of a deformable-mirror spatial light modulator
Optics Letters
|September 11, 2009
Abstract:
Some of the optical characteristics of a recently developed solid-state deformable-mirror spatial light modulator have been investigated. The device is composed of an array of 128 x 128 pixels, with each pixel consisting of four hinged reflective rectangular surfaces. Modulation at video frame rates has been achieved, providing real-time displays in coherent light, which may be useful for a variety of optical processing and computing applications.

Imaging Biological Samples with Optical Microscopy
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.

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,...
