A scientific-grade ccd/cmos camera capable of recording time stamps and star scans

Abstract

The invention discloses a scientific-grade CCD / CMOS camera capable of recording time stamps and star image scanning. The CCD / CMOS camera of the invention can internally realize the one-to-one correspondence between the exposure center time of the captured image and the captured image, so as to avoid the problem of incompatibility between the captured image and the time stamp caused by the problem of image capture in different operating systems, especially to avoid frame transfer. The problem that the time stamp recorded in the exposure mode does not correspond to the image due to the inability to realize frame transfer by reading the CCD; through the scanning processing of all the star images on the image, the amount of data that needs to be transmitted is reduced to less than 1% of the original image data, In the case of a lower readout speed, the data transmission time can be effectively reduced, and it is suitable for promotion and use in the technical field of space debris monitoring.

Description

technical field [0001] The invention belongs to the technical field of astronomy, in particular to a scientific-grade CCD / CMOS camera capable of recording time marks and star image scanning. Background technique [0002] In many fields such as scientific research and military, it is necessary to monitor space debris, and to give the angle measurement data of each observation moment of space debris, so as to determine the orbit of space debris, obtain accurate information of space debris, and provide information for on-orbit spacecraft. Safely provide the most primitive supporting data. [0003] The invention of CCD in the 1970s replaced the traditional photographic celestial observation and became an effective means of satellite surveillance at that time. With the frequent space launch activities, the number of times has increased from several or dozens of times a year to more than 100 times. The amount of space debris in space is increasing, and the number of space debris...

AI Technical Summary

Problems solved by technology

[0007] 3) It can output exposure square wave TTL level signal, but the frame transfer readout CCD is read out during the exposure process, usually there is no exposure square wave TTL level signal;

[0008] However, with more and more space debris in space, traditional scientific-grade CCD and CMOS cameras are gradually unable to meet the development requirements of space debris cataloging
