Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0020] see figure 1 and Figure 4 , a follow-up laser semi-active guiding lens detection system, comprising: a lens barrel 2 and an optical system arranged inside the lens barrel 2, the optical system is sequentially provided with a filter 10 and a lens A11 along the light input to output direction , lens B12, four-quadrant detector 5, the lens A11 is an aspheric mirror, the lens B12 is a spherical mirror, and the air distance between the lens A11 and the lens B12 is 4.3mm.

[0021] The front side of the lens barrel 2 is a structure for fixing the optical filter 10 . The lens A11 and the lens B12 are sequentially fixed inside the lens barrel 2 . Inside the lens barrel 2, there is a first pressure ring 3 between the filter 10 and the lens A11, a second pressure ring 4 between the lens A11 and the lens B12, and a four-quadrant detector between the lens B12 and the re...

Abstract

The invention discloses a follow-up laser semi-active guiding lens detecting system and method. The system comprises a lens barrel and an optical system arranged inside the lens barrel, the optical system comprises an optical filter, a lens A, a lens B and a four-quadrant detector which are sequentially arranged in the light direction from input to output, the lens A is an aspherical mirror, the lens B is a spherical mirror, and the air distance between the lens A and the lens B is 4.3 mm. The method is easy to implement, the device is easy to install and adjust, and an output electric signalof the four-quadrant detector is stable.

Description

technical field [0001] The invention belongs to the field of electronic information technology, relates to the field of laser detection, in particular to a detection system and method for a semi-active laser guided lens with a follow-up laser. Background technique [0002] Laser guidance mainly adopts three guidance methods: laser semi-active guidance, laser active guidance and laser beam driving guidance. Laser semi-active guidance is a guidance method with the earliest development, the most mature technology and wide application in the laser guidance system. Its working process is to use an independent laser irradiator to irradiate the designated target, the missile seeker receives the laser echo signal emitted by the target, the four-quadrant detector receives the optical signal, and guides after passing through the signal processing system. At present, the laser guidance system based on the four-quadrant detection system in China is complicated to install and adjust, an...
