Problems solved by technology

[0004] However, the current micro-mirror scanning device still has many deficiencies in integration and modularization. If the various components of the system work separately, it will not only bring difficulties to the design of each part of the system, but also bring difficulties to the micro-mirror scanning system. The layout itself and its carrying on the micro-nano satellite have caused great difficulty, and will make the structure of the entire system not compact enough, resulting in an increase in volume

Embodiment Construction

[0026] Concrete technical scheme of the present invention is as follows:

[0027] The micro-integrated non-cooperative target detection device is structured as a module box, in which lasers, apertures, beam splitters, MEMS micro-mirrors and signal processing circuits are integrated.

[0028] The laser emits a continuous wave laser beam modulated by a signal, passes through the diaphragm and the beam splitter, and then transmits to the MEMS micro-mirror; the MEMS micro-mirror reflects the laser beam to realize two-dimensional scanning, and outputs Two-dimensional deflection angle measurement signal; the scanning beam is reflected by the non-cooperative target, passes through the MEMS micro-mirror again, and is reflected to the beam splitter, and finally reflected by the beam splitter to form an echo signal that is captured by the beam splitter received by the signal processing circuit. The signal processing circuit calculates and processes the modulation signal, the echo signa...

Abstract

The invention provides a micro integrated non-cooperative target detection device, and belongs to the technical field of micro electro mechanics. The device is characterized by comprising a laser emission part, an optical scanning part and a signal receiving and processing part, which are integrated in a 100mm*35mm*50mm module box; the continuous wave laser beam undergoing signal modulation passes through a diaphragm and a beam splitter and then is irradiated on an MEMS micro reflection mirror serving as the optical scanning part, the continuous wave laser beam undergoes two-dimensional scanning, and the beam reflected back by a non-cooperative target is reflected by the MEMS micro reflection mirror and the beam splitter respectively and then processed by the signal receiving and processing part so as to output the information about the relative distance and orientation of the non-cooperative target. The micro-integration non-cooperative target detection device of the invention is more compact in structure and much smaller in volume.

Description

technical field [0001] The invention relates to a micro-integrated non-cooperative target detection device, which belongs to the field of opto-mechanical-electrical integration technology and MEMS technology (Micro-Electro-Mechanical System). Background technique [0002] Autonomous scanning is a key technology for non-cooperative target detection in space. It is mainly used to scan and detect non-cooperative target spacecraft in a certain area of ​​space, and measure their relative distance and relative orientation. [0003] With the development of micro-mechanical and MEMS technology, micro-mirror scanning has become a new type of scanning method. The deflection occurs at the bottom, so as to change the deflection angle of the incident light and realize the scanning of a certain area. MEMS micro-mirror has the characteristics of small size, light weight, low power consumption, fast scanning rate, and high measurement accuracy. The scanning device based on MEMS micro-mirro...
