Signal processing platform applicable to multi-sensor self-adaption optical system

Abstract

The invention provides a signal processing platform applicable to a multi-sensor self-adaption optical system. The signal processing platform comprises a plurality of signal processing modules (1) with a bus switch, an interconnection rear panel (2) based on a CPCI (Compact Peripheral Component Interconnect) bus structure, an expansion I / O (Input / Output) board (3) and a monitoring host (4). With the adoption of the structure, the signal processing platform provided by the invention can be used for processing wave-front signals of a plurality of sensors in parallel and combining low-delay data among the sensors in parallel; the good expandability, the generality, the clipping property and the small size of the signal processing platform can be realized due to a dynamic bus structure with a switch and a changeable operation signal processing module structure; and the signal processing platform is applicable to processing the self-adaption optical wave-front signals in various applicable fields.

Description

technical field [0001] The invention relates to the technical field of an adaptive optics high-speed wavefront processing system, in particular to a signal processing platform suitable for a multi-sensor adaptive optics system. Background technique [0002] Large-scale ground-based telescopes are usually equipped with an adaptive optics system to improve the imaging resolution of the telescope system, and a key problem for the adaptive optics system to correct atmospheric turbulence is the beacon light source, because it may not be possible to find a suitable star as a signal within the equi-halo angle. Therefore, people use laser guide stars as artificial beacons to improve the sky coverage of adaptive optics systems. The artificial beacon is a "point" light source at a finite distance. The overlapping area between it and the main laser is a cone. Outside the cone, the phase information of the main laser is not carried by the beacon light, that is, outside the cone The are...
