ABSTRACT:
A fiber optic viewing device has in a first embodiment, a color-preserving image intensifier positioned at the viewing end thereof. In a second embodiment, an input light source is sequentially modulated through a cycle of wavelength sets. The resulting image is intensified and recolored by an output recoloring filter which is synchronized with the input light modulation. In yet another embodiment, a set of red, green and blue LEDs are sequentially modulated by a controller to provide input light. A CCD camera receives the resultant intensified image and converts it to video format. A video processor stores frames during a cycle of modulation and then integrates the frames for viewing in full color.
