ABSTRACT:
Optical sensors, more particularly infrared sensors, use an array of MEM micromirrors to chop a light beam impinging on an array of sensors of an imaging device to minimize the influence of thermal noise. The array of micromirrors preferably switches the beam impinging on the array of sensors between an image to be analyzed and an image of a reference black body at a clearly defined temperature. These sensors are not cooled and require no cryogenic devices.
