Abstract

The invention discloses a full-spectrum light target simulator, which comprises a collimation optical system, a light source system, a lifting system and an automatic control system. The optical system is an infinite distance-light target simulation system. The light source assembly comprises a visible light source, a black body radiation source and an integrating sphere dodging system; the lifting system comprises a first servo motor, a guide rail and a lifting table; the automatic control system is used for controlling the switching of the light source components and the lifting system; thecollimation optical system and the light source assembly are both installed on the lifting table, the light source assembly is located on one side of the collimation optical system and connected withthe collimation optical system, and the light source assembly and the lifting system are both connected with the automatic control system. According to the invention, full-spectrum image quality detection can be carried out on a large-aperture and long-focal-length space optical remote sensor.

Description

technical field [0001] The invention relates to the testing field of space detection equipment, in particular to a target simulator capable of emitting full-spectrum parallel light beams. Background technique [0002] With the increase of the aperture and focal length of space optical remote sensors, optical target modules with larger apertures and longer focal lengths are required for detection and image quality evaluation. Optical target modules with larger apertures and longer focal lengths have higher requirements for image quality, focal plane position accuracy, and stability of the test environment. However, the guarantee of the caliber and focal length of the optical target mold equipment, the guarantee of the image quality level of the collimation system, the guarantee of the position accuracy of the focal plane of the collimation system, and even the guarantee of the stability of the test environment will eventually follow the gradual improvement of the technical in...
