A calibration method and device for the responsivity parameters of an array terahertz detector

Abstract of Descriptions The invention provides a calibration method and device for the responsivity parameters of an array terahertz detector. The device of the present invention includes at least five parts: a terahertz transmitting module, a terahertz receiving module, a two-dimensional translation device, an optical lens group, a data acquisition processing and a display module. The calibration method and device for the responsivity parameters of an array terahertz detector of the present invention uses the calibration method of standard single-pixel detector comparison, which can realize precise calibration of the array terahertz detector and reduce the uncertainty of the value transmission. By adding a surveillance detector in the wave path, the influence of the stability of the wave source on the transmission result is eliminated, and the calibration result is more accurate.
