Embodiment 1

[0039] Such as Figure 1-6 As shown, the moving point target image generation device under laser interference conditions includes a long-wave infrared laser, a laser aiming aperture, a laser attenuation controller, an infrared laser beam expander system, a beam combiner, an infrared point target simulation device, a two-dimensional turntable, a one-dimensional Tilting table, control system, infrared camera, image acquisition system;

[0040] The long-wave infrared laser is responsible for generating long-wave interference laser. The long-wave interference laser enters the laser attenuation controller through the laser aiming aperture. In order to reduce the volume and weight of the device, a long-wave infrared laser with a quantum cascade mechanism is used. The output power of the laser is greater than 1W. The typical value of the incident laser diameter is 2mm, and the divergence angle (full angle) of the laser beam is 4mrad.

[0041] The laser attenuation controller mainly ...

Abstract

The invention relates to a motion point target image generation device under a laser interference condition. The motion point target image generation device comprises a long-wave infrared laser, a laser aiming diaphragm, a laser attenuation controller and the like. The long-wave infrared laser generates a long-wave infrared interference laser, the long-wave infrared interference laser enters the laser attenuation controller through the laser aiming diaphragm, and the laser attenuation controller adjusts and controls laser energy emitted by the long-wave infrared laser; an infrared laser beam expanding system adjusts a laser beam and simulates an infinite observation process; the infrared point target simulation system simulates a sub-pixel-level or pixel-level target, simulates an infiniteobservation effect and moves along a one-dimensional direction, and a moving speed and a moving range are controlled by the control system; a beam combiner completes scene coupling of the laser beamand the infrared point target simulation system; the infrared camera generates a long-wave infrared image; and an image acquisition system acquires images shot by the infrared camera under the controlof the control system, and completes the generation of a motion point target image sequence under the laser interference condition through continuous work.

Description

technical field [0001] The invention belongs to the field of image generation under laser interference conditions, and relates to a moving point target image generation device. Background technique [0002] Infrared image simulation generation is widely used in optoelectronic imaging system testing and hardware-in-the-loop simulation experiments, and can provide test image sequences for image processing algorithms. With the continuous development of photoelectric countermeasure technology, laser interference has gradually entered the application field. How to simulate and generate infrared image sequences under the condition of laser interference is a new problem in the field of infrared imaging simulation. [0003] There are two types of traditional technical solutions. One is computational simulation generation. According to the laser transmission theory and the response characteristics of the detector, images under laser interference are generated. This method can combin...
