Problems solved by technology

[0006] To use a CCD receiving device in a spectrometer, it is necessary to have specific requirements for the performance indicators of the CCD receiving device. However, the current high-sensitivity CCD detection device has only independent test methods and detection methods for its own parameter performance indicators. The test equipment is large Visible light integrating sphere test system, the test system is large (diameter > 80Cm), expensive, long test time, and can only provide effective

Abstract

The invention discloses a novel full-band CCD detector performance evaluating system and method. The system comprises an ultraviolet visible section spectroscopic detecting system, a CCD detector data collection system, and a CCD detector performance evaluating system, wherein the ultraviolet visible section spectroscopic detecting system is connected with the CCD detector performance evaluating system through the CCD detector data collection system. The method comprises the following steps of: (1) correcting wavelengths of the system; (2) calibrating energy of the system; (3) detecting stability and sensitivity of the full-wavelength data of the CCD detector; and (4) evaluating the full-wavelength performances of the CCD detector. The invention provides the cheap, portable and fast full-band CCD detector performance evaluating system and method, thereby ensuring that the evaluation of the performances of the CCD detector is simple, fast and comprehensive and the good application of the CCD detector to the optical spectrum instrument.

Description

Technical field: [0001] The invention relates to a spectrum analysis device, in particular to a system for evaluating the performance of an optical signal detector in a spectrum instrument and a method for realizing the evaluation by the system. Background technique: [0002] There are three main types of optical signal detectors for spectroscopic instruments, namely thermal detectors, photon detectors, and semiconductor image sensors. The optical signal detectors of modern spectroscopic instruments are mainly PMT detectors of different specifications, and some use CCD as detectors. As a commonly used main detector, PMT has a glorious history in the development of atomic absorption spectrometers with high gain, high sensitivity, fast response and low cost, and its technology is also constantly being developed and updated. The CCD detector detects the signal through the storage and transfer of electrons, and its quantum efficiency is high. Based on the different measurement ...
