A differential imaging system using fluorescence, polarization and spectrum modulation has been developed. The fluorescent system can provide clear images even in a normal bright room by subtracting a normal image from an image obtained under ultraviolet light irradia tion. Polarization-controlled images can be provided from the difference between images taken with differential polarization of light using a liquid crystal filter. Transparent images and reflection images on a glass window are selectively obtained. Spectrumdifferential images have been also acquired using a variable interferometer. The system reveals characteristic spectral images of objects, and the mechanism of wavelengthdifferential imaging has been confirmed by spectral simulations.
