Problems solved by technology

This increases the power consumption of the system, and most of the power consumption is wasted on the larger circulating water temperature chamber, resulting in lower efficiency; moreover, the entire temperature control system has a large volume and weight
This seriously restricts the practical engineering application of standard detectors in field, airborne and spaceborne optical radiation calibration

Embodiment Construction

[0020] See Figure 1, Figure 2, Figure 3, Figure 4.

[0021] The overall structure of the embodiment of the temperature-controlled multi-channel optical radiation standard detector of the present invention is shown in Figure 1, including: a multi-channel optical radiation standard detector 1, a plurality of digital temperature sensors DS18B20 2 fixed on the standard detector, and the standard The semiconductor thermoelectric cooler Peltier 3 connected to the detector, the radiator 4, the intelligent temperature control circuit and the human-machine interface circuit connected to the output end of the digital temperature sensor.

[0022] Good steel thermal contact must be maintained between the standard detector and multiple DS18B20 temperature sensors and between the standard detector and the Peltier in this implementation, so as to achieve the ideal temperature control effect. In the actual connection, thermal silica gel bonding or clamp connection can be used. When the bondi...

Description

technical field [0001] The invention belongs to the technical field of standard detector temperature control for high-precision optical radiation calibration. Background technique [0002] High-precision radiometric calibration technology is one of the main supporting technologies of modern space remote sensing. The new multi-channel optical radiation standard detector based on the filter radiometer has broad application prospects in high-precision radiometric calibration in the field, airborne and onboard. In engineering applications, temperature characteristics are a key factor affecting the absolute accuracy and stability of standard detectors. Therefore, precise temperature control of optical radiation standard detectors is required. (Li Zhaozhou, Zheng Xiaobing, Wu Haoyu et al. "Study on Temperature Characteristics of High Precision Spectral Radiation Standard Detectors", Acta Optics Sinica Vol. 24 No. 2, February 2004) [0003] So far, the multi-point distributed te...
