探测器表面涂有金黑的电校准热电辐射计广泛应用于对辐射功率的绝对测量。电校准热电辐射计是以热电探测器为基础研制的,同时又采用了光学调制和零位平衡技术,它对辐射功率进行绝对测量的基础是用经过调制的辐射功率和电功率交替加热覆有黑涂层和加热体的热电探测器,并使黑涂层所吸收的辐射功率与加热体产生的电功率相互等效,这样就直接将辐射功率测量转变为电功率测量了,而电功率的测量易于获得很高的精度,于是只要测量电功率,就实现了对辐射功率的准
The detector surface is coated with gold and black electrical calibration thermoelectric radiometer is widely used in the absolute measurement of radiation power. Electrically calibrated pyroelectric radiometers are based on pyroelectric detectors and are based on optical modulation and zero-balance techniques. The basis for absolute measurement of radiated power is the alternating heating of black Coating and heating of the pyroelectric detector, and the black coating absorbed by the radiation power and heating power generated by the mutual equivalent, so that the radiation power measurement directly into the measurement of electrical power, and the measurement of electrical power is easy to get very High precision, so as long as the measurement of electrical power, to achieve the prospective of the radiation power
