1. A fluorescence imaging system comprising:
- a light source for irradiating an object to be viewed;
a beam-splitting system for forming individual displaced images of said irradiated object;
a plurality of wavelength filters disposed in the path of said individual images, said filter selected to have different passband frequencies, such that said images are filtered differently;
a detector for receiving said individual displaced images which pass through said filters, said detector providing a plurality of signals representing the same image point of each of said displaced images; and
,circuit means connected to receive said signals representing the same image point for each of said displaced images, said circuit means generating a weighted signal value of said individual signals, such that a single image signal is produced for each image point of an image of said object.

Abstract
A fluorescence imaging system. A light source irradiates an object to be viewed. The irradiated object is imaged through a beam-splitting system to form individual displaced images of the object. The displaced images are further filtered in a filter having a frequency passband different from the other filters. The filtered images are imaged on a detector. The same image point of each image is detected and converted into an electrical signal. A circuit means is provided to receive the signals of each common image point, and weight the same. The weighted signal represents an image point pixel. The weighted pixels are displayed as an image of the object having improved contrast.
