An energy-efficient intelligent temperature control system for ccd detector cooling device based on spectrometer

Abstract

The invention discloses a high-energy-efficiency intelligent temperature control system for a CCD (charge coupled device) detector refrigerating device based on a spectrograph. The high-energy-efficiency intelligent temperature control system comprises a temperature sensor, a temperature signal processing module, a CCD data collecting module and a main control CPU (central processing unit) module, wherein the temperature sensor is used for obtaining the temperature of the current CCD detector and outputting temperature signals, the temperature signal processing module amplifies the temperature signals and inputs the temperature signals into a control module after the temperature signal conversion, the CCD data collecting module collects CCD data and inputs the CCD data into the main control CPU module, the main control CPU module calculates the current signal-to-noise ratio of the CCD detector according to the CCD data, and sends out instructions to the control module according to the signal-to-noise value, a direct current refrigerating power supply is controlled to supply electricity to a semiconductor refrigerating TEC, and the semiconductor TEC changes the work temperature of the CCD detector until the signal-to-noise ratio does not influence the equipment measuring data.

Description

technical field [0001] The invention relates to a temperature control system, in particular to an energy-efficient intelligent temperature control system based on a spectrometer and used for a CCD detector refrigeration device. Background technique [0002] CCD, English full name: Charge-coupled Device, Chinese full name: Charge-coupled device. It can also become a CCD image sensor. CCD is a semiconductor device that converts optical images into digital signals. It has the characteristics of stable performance and high sensitivity. [0003] The noises of CCD detectors mainly include photon particle noise, dark current noise, readout noise (amplifier reset noise and output amplifier noise), clock induction noise, etc. Especially when working at room temperature, dark current noise and readout noise are particularly Large, these will have an impact on the final data. The impact of noise is often much greater than the impact of visible light, and the size of the noise signa...
