[0027] The present invention will be further described below in conjunction with the description of the drawings and the specific embodiments.
[0028] Fast multi-channel spectrometer is a new type of instrument developed on the basis of single-channel spectrometer. One of the main applications of this fast multi-channel spectrometer is the detection of LED products. A general single-channel spectrometer can only detect one optical signal, while a multi-channel spectrometer can simultaneously detect multiple signals in parallel. The working principle of the multi-channel spectrometer is as attached figure 1 Shown.
[0029] From a structural point of view, the fast multi-channel spectrometer used in the LED spectral characteristic parameter test of the present invention is mainly composed of an optical system, a detector, a signal processing circuit, a single-chip main control system, a control signal generation circuit, an A / D acquisition system, and serial communication.
