Abstract

The invention discloses a dynamic optical signal processing method, device and equipment and a storage medium. The method comprises the following steps of: obtaining a dynamic optical signal curve after a plurality of reaction cups are subjected to light measurement operation; based on the dynamic optical signal curve, using a positioning algorithm to obtain position information of a dynamic optical signal central point; and obtaining a digital signal value corresponding to the dynamic optical signal central point by using the position information of the dynamic optical signal central point. Therefore, the technical problem that the centermost position of the dynamic optical signal of each reaction cup cannot be accurately positioned can be solved, and the positioning precision and measurement accuracy of the dynamic optical signal central point can be improved.

Description

technical field [0001] The invention relates to the field of optical signal processing, in particular to a dynamic optical signal processing method, device, equipment and storage medium. Background technique [0002] At present, the commonly used method to determine the center point of dynamic optical signal is to use oscilloscope to measure and calibrate. Such as figure 1 As shown, the oscilloscope simultaneously measures the sampling timing control signal of the detector and the dynamic optical signal, adjusts the rising or falling edge of the timing signal to a fixed time interval T1 from the rising or falling edge of the dynamic optical signal curve, and then uses the timing signal The rising edge or falling edge of the oscilloscope is used as the reference, and the corresponding measured value on the dynamic optical signal curve is read after a certain time delay T2; and the shortcomings of the oscilloscope measurement and calibration method in the prior art are: [0...
