Abstract

A scene simulator for generating picture information in real time for testing picture resolving sensors, in particular for testing infrared sensors in target tracking seeker heads, comprises a micro-mechanical mirror array, which consists of a two-dimensional array of mirror elements, which are arranged to be moved between first and second operative positions in response to actuating signals. An illuminating device is arranged to uniformly illuminate the mirror array. The light of the illuminating device, in the first operative position of a mirror element, is reflected to pass by a sensor to be tested and, in the second operative position of the mirror element is reflected into the path of rays of the sensor. A picture computer and driver electronic serve to move the mirror elements into the first or second operative positions such that the sensor to be tested observes a simulated object scene.
