Beschreibung
Zusammenfassung:The invention relates to the technical field of optical equipment, and provides a coaxial telescope secondary mirror retroreflection suppression device which comprises a primary mirror and a secondary mirror, the primary mirror and the secondary mirror are coaxially arranged on the optical axis, and an inclined reflector is erected on the side, close to the primary mirror, of the secondary mirror and used for reflecting retroreflection stray light; the center of the inclined reflector and the optical axis of the secondary mirror are coaxially arranged, and the aperture of the inclined reflector is determined according to the parameters of the primary mirror and the secondary mirror. According to the invention, the inclined reflector is used to reflect the detection laser light irradiated at the central part of the secondary mirror to the side surface, so that the detection laser light is prevented from returning to an optical detection system according to an original light path to form backward reflection str
