Paper Abstract

Recently, AOTF infrared spectrometer attracts more and more attention, and the speed of obtaining spectrum curve depends on not only the number of spectral sampling point, but also the spectral sampling rate. This paper introduces a circuit design method, in which a precision low noise amplified circuit has been used. Compared with the traditional lock-in circuit, this method has an advantage of fast sampling speed, which could be up to 10us orders of magnitude in theory. The experiment was done according to the above theory. The result shows that sampling speed could reach 102us magnitudes.
