Patent ID: 10054395

Abstract:
A multi-spectral weapon sight optical system, a multi-spectral weapon sight, and a multi-spectral weapon sight system are disclosed. The multi-spectral weapon sight optical system includes first and second catadioptric optical systems arranged along a common axis and have a common aperture. The first catadioptric optical system forms a first on-axis image from first radiation having a first wavelength band while substantially transmitting second radiation to the second catadioptric optical system wherein the second radiation has a second wavelength band. The second catadioptric optical system forms a second on-axis image using the second radiation. First and second image sensors respectively receive the first and second images and form respective first and second digital images, which are then electronically fused to form a fused image. The fused image is displayed on a display and viewed as a visible display image using a day sight.
