Application of Single Chip Computer in Control and Detection Systems of Spectrometer

A new system using single chip computer AT89C51 as the central controller for controlling and detecting of signal of the spectrometer is put forward in the paper.The measured signals are sent to the computer for data analyzing and processing.The characteristics of the photon counter is studied and the related ports of the single chip computer are analyzed.The arrangement techniques for the related software and hardware are summarized and the experimental spectral patterns are given.
