Research on high-precision real-time automatic detector

This paper expounds the working principle and the development program of on-line real-time automatic detector with high precision. By a series of techniques, such as combining driving frequency regulation and integration time adjustment, the independent regulations of high-speed synchronous counter, data transmission clock and transfer clock of optical signal are achieved, and the technical problems that the clock synchronization is difficult to control as well as the signal to noise ratio (SNR) varies with the CCD output signals are solved. The dealing circuit of constant current power is designed to ensure the light-emitting stability of light source, and the amount of data is greatly reduced by the narrow pulse center collection. The instrument has several characteristics, such as high precision, on-line and real-time, non-contact measurement, fast measuring speed, and so on.
