Shade reducing aperture stop for thermal imaging systems
An aperture stop is provided near the detector imaging lens of a thermal imaging system to prevent the infrared detector from viewing portions of the thermal imaging system itself, particularly the walls of the optical housing and the housing of the scanner within the optical housing. This eliminates "shading" problems which can occur in thermal imaging systems having a moving scanner within the optical housing.
