Embodiment Construction

[0019] An adaptive optical processing platform, including an off-board module 4, an on-board transceiver module 5, an on-board processing module 8, a data storage module 7, a main control module 6, an internal communication bus 9, an external data transmission bus 12, and an external 10G Ethernet communication bus 10 . The off-board modules are of three types, including class 1 for processing Shaq-Hardman wavefront sensing data, whose main data is image data; class 2 for processing laser guide star control, whose main data are commands and Parameters; processing DM deformable mirror control class 3, its main data is the command and DM deformation value transmitted from the machine. The communication mode between the three types of modules and the machine is high-speed optical fiber with a custom prefix; the communication mode between this processing system and other external systems 11 is 10G Ethernet (the protocol is UDP or TCP / IP), and the internal data bus on the machine is...

Abstract

Provided is a self-adaptive optical processing platform. An off-board module communicates with an on-board receiving module through an over-board data transmission bus, the on-board receiving module receives off-board data transmitted by the over-board data transmission bus, the off-board data are directly transmitted to a main processing module through an internal communication bus, after the main processing module processes the data, the data are transmitted to a data storage module through the internal communication bus for storage, and the data can also be invoked by a master control module through a memory. Instruction parameters of an outer device in need of control are transmitted to the corresponding off-board module by a master control computer through the over-board data transmission bus, and the control result is uploaded to the master control module by the off-board module through the over-board data transmission bus. The self-adaptive optical processing platform solves problems of the existing self-adaptive optical system of huge structures, low intelligentization and difficulty in updating and upgrading during wave-front correction processing, and can be applied to self-adaptive optical systems with multi-laser guide stars, Hartmann wave-front detectors and multi-deformation mirrors.

Description

technical field [0001] The invention relates to the technical field of adaptive optics, in particular to an adaptive optics processing platform for adaptive real-time data processing and control. Background technique [0002] At present, the adaptive optics processing system has a microprocessor platform based on FPGA+DSP and a computer platform relying on computer CPU processing. The document "SPARTA, the ESO Standard Platform for Adaptive Optics Real Time" reveals a processing platform connected by VXP with FPGA+DSP as the processing core; the document "An FPGA Based Computing Platform for Adaptive Optics" reveals a processing platform based on FPGA The main processing platform; the above two processing platforms have the advantage of strong data processing capabilities, but because they involve a large number of electronic design and system coordination problems, it is not easy to upgrade, difficult to maintain, and the program is solidified. reaction. The document "Dur...
