Digital micro-mirror control method suitable for atomic fluorescence chromatic dispersion detection system

Abstract

The invention relates to a digital micro-mirror control method suitable for an atomic fluorescence chromatic dispersion detection system. The method comprises the following steps: choosing the control mode of a digital micro-mirror from three modes: an automatic control mode, a whole spectrum selection mode, and a single waveband selection mode; choosing the automatic control mode, when the element to be detected is a specific element, and controlling the digital micro-mirror to turn over according to the preset digital micro-mirror control parameters; choosing the whole spectrum selection mode, when a sample to be detected is subjected to whole spectrum detection, and controlling the digital micro-mirror to turn over according to the default values of the preset digital micro-mirror control parameters or manually-input preset values; choosing the single waveband selection mode, when the detection is carried out under a self-defined waveband, and controlling the digital micro-mirror to turn over according to the manually-input digital micro-mirror control parameter set values. The provided method has the characteristics of simple command structure, rapid control speed, and little resource utilization, and is capable of carrying out high-speed and stable atomic fluorescence chromatic dispersion detection on different elements with different characteristics for many times.
