Real time optical correlator architectures using a deformable mirror spatial light modulator
Abstract:
The recent production of a deformable mirror device (DMD) spatial light modulator has naturally led to techniques of using this device in popular optical correlator architectures. In this paper, the DMD is used in both joint transform and VanderLugt arrangements. In some cases, the DMD is used as the input device to a single stage joint transform correlator, and in other cases it is used as the filter device in a VanderLugt correlator. A liquid crystal TV is also used for real time addressing of filters displayed on the DMD.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
