An integrated white-light low-light infrared target simulator

Abstract

The invention discloses an integrated white light low-light infrared target simulator, which comprises a main mirror, a secondary mirror, a reticle, an illumination light source and a light source controller. The surface of the illumination light source is electrically connected to the surface of the light source controller through wire The lighting source is located behind the reticle, the lighting source includes a housing, and a white light infrared light source circuit board is fixedly connected to the inner cavity of the housing. The invention relates to the technical field of infrared target simulators. The integrated white light low-light infrared target simulator adopts the off-axis Cassegrain optical system, which not only has the advantages of large aperture, long focal length, no chromatic aberration, and no occlusion in the center of the off-axis reflective system, but also has the advantages of coaxial jamming The Green system has the advantages of small size and light weight. Through the design of double-layer circuit boards and double-layer homogeneous glass, three uniformly distributed low-light LEDs and a halogen lamp are selected, combined with off-axis Cassegrain optical systems and metal hollow cross plates , a white light and low-light infrared target with the same outgoing optical axis.

Description

technical field [0001] The invention relates to the field of infrared target simulators and technologies, in particular to an integrated white-light low-light infrared target simulator. Background technique [0002] The white light and low light infrared target simulator is mainly used for the parallelism correction of the optical axis of the three sighting and sighting equipment, the white light sighting mirror, the low light night vision device, and the infrared thermal imager. [0003] Most existing target simulators use coaxial Cassegrain optical system and off-axis reflective system when simulating three kinds of targets. The coaxial Cassegrain optical system has long focal length, large aperture and light weight, and can be used for Outdoor and indoor optical axis correction, but the center of the optical axis is occluded, and it is necessary to avoid the central occlusion when using it, which is not easy to operate; the off-axis reflective system has a long focal leng...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an integrated white-light low-light infrared target simulator, which solves the problem that the coaxial Cassegrain optical system is long in length and heavy in weight, is only suitable for indoor optical axis correction, and does not have portability. And the operation of the calibration process is more complicated, and the replacement of the illuminator may reduce the problem of calibration accuracy
