Abstract
A camera concurrently produces an orthographic map and map spectral content. Illumination from an image passes through a phase modulator and the resulting rotating photo-flux phase is converted to an electrical signal by multiple adjacent sensors of detectors of array of detectors. The amount of unwanted illumination reaching the sensors is reduced by a set of baffles that shield and protect the transducers from unwanted out-of-field light and other light sources.
