Abstract
The problem of automating the measurement of the dynamic characteristics of photodetectors of various types with individual design features has been solved. The relevance of the topic is related to the need to minimize the personalization of measurements of the duration of the transient process of photodetectors, which become a limiting factor with an increase in the speed of information transfer. A method free from subjective visual measurements is proposed for determining the response time of photodetectors to an incident light pulse. To confi rm the operability of the proposed method, numerical simulation was carried out to determine the voltage rise time at the output of the photodetector from the values of the frequencies of its zero harmonics. The possibility of using the developed method for estimating and testing the rate of transient photoelectric conversion has been experimentally established. The proposed method will automate the process of output control in the in-line production of industrial batches of photodetectors.
