Abstract

At present, airborne optoelectronic products mostly use multi-sensors (visible light, infrared, laser, etc.) to coordinate the detection, recognition and tracking of threatened targets. Therefore, higher requirements are placed on the optical axis consistency of multi-sensors.In response to this demand, the visible light, laser and infrared astigmatism axis detection equipment suitable for a wide temperature range (-55°C~+70°C) are designed.The collimating optical system of the optical axis detection device adopts a common aperture design, and uses an off-axis parabolic mirror to achieve collimation of the light beam.For a wide temperature environment, the optical system adopts passive athermal design.Compared with the previous independent radiation sources, the multi-band composite radiation source is used to integrate infrared, visible and laser radiation sources, saving space, simplifying the operation steps and reducing the difficulty of use.The optical axis detection equipment needs to be used in the temperature box. Compared with the previous manual operation of the temperature box, this solution uses electric means to realize the optical axis measurement, which greatly improves the use efficiency and reduces the risk of personal injury.The optical axis detection equipment designed finally can control the collimation optical system parallel difference within 10″under wide temperature range and within 6″ under 20°C.
