MONOLITHIC TUNABLE MULTI-SPECTRAL IMAGING SENSOR BASED ON MICRO-SCANNER ARRAY
Phone: (310) 530-1416
Physical Optics Corporation (POC), Applied Technology (AT) Division, proposes to develop a unique multispectral imaging sensor (MSIS) system. POC's approach is to reduce the functional units of a conventional scanning spectrometer to microscopic size. The resulting system will be very compact, low-volgate, high resolution (<1nm), widely tunable (visible to IR), highly rugged and monolithic. This approach uses multispectral imaging and basically divides the input image intopixel (or small numbers of pixels) size micro regions, and then spectrally filters each region using an array of micro-imaging spectrometers. Each region can be selectively tuned to a specific narrow wavelength band within a wide wavelength range with very high contrast (i.e.,OD>6) of the dispersed light using a fast switching LC phase modulator array. Because of their compactness, several such sensor modules for different (broad) spectral bands can be integrated, providing scanning over a full wavelength range (visible - to IR).
