Abstract

The invention discloses an aligning correction device and method for space navigation detector ground calibration. Accuracy aligning of an X radiation source and a detector can be achieved through the device, and the parallel aligning error is less than 0.02 degree and the central aligning error is less than 1mm. The device comprises a front-vehicle optical measuring platform and a rear-vehicle optical measuring platform. A detector is fixedly installed on the front-vehicle optical measuring platform. An X radiation source is fixedly installed on the rear-vehicle optical measuring platform. The front-vehicle and rear-vehicle optical measuring platforms are located at front and rear ends of a vacuum beam line channel respectively. Firstly, parallelism aligning is carried out, the posture of the front-vehicle or rear-vehicle optical measuring platform is adjusted, and thus an image of a laser light spot is located at an imaging center of a parallelism measuring CCD camera; then height and horizontal displacement aligning is carried out, the posture of the front-vehicle or rear-vehicle optical measuring platform is adjusted, thus the image of the laser light spot is located at the imaging center of the displacement measuring CCD camera, and finally aligning of the X radiation source and the detector is achieved.

Description

technical field [0001] The invention relates to the technical field of space detectors, in particular to an alignment and deviation correction device and method for ground calibration of a space navigation detector. Background technique [0002] Space navigation detectors generally need to be calibrated on the ground first, but at present there are no specialized institutions and test devices for the calibration of space navigation detectors in China, and they are still in the exploratory stage. [0003] Relying on the major special project of the second-generation navigation of the final assembly "Pulsar Navigation Ground Test System", the 513 Institute has developed and completed the largest domestic large-scale vacuum test equipment with the most complete functions and the highest attitude adjustment accuracy-vacuum beamline channel. The vacuum beamline channel has an outer diameter of 2.1 meters and a total length of 17 meters, providing a vacuum working environment for ...
