Photoelectricity sensing element frequency characteristic measuring method and photoelectricity sensing element response characteristic measurement equipment

摘要

PURPOSE: To highly accurately measure frequency characteristics of a photoelectric transducer in real time by noting noise generated together with a light emission phenomenon and using a light source generating a light output incoherent in time whose frequency characteristics of power spectrum density are known. ;CONSTITUTION: A light output generated from a light source 1 which is incoherent in time and whose frequency characteristics of power spectrum density are known is received by a photoelectric transducer A to be measured, and a frequency component value included in this signal is detected by an electric signal frequency detecting part 2. The detected output signal value is corrected with reference of the known frequency characteristics of power spectrum density, and the corrected value is output from a signal calculation ouptut part 3 as response characteristics of the photoelectric transducer to be measured.;COPYRIGHT: (C)1993,JPO&Japio
