As shown in the figure, when the laser outputs at each wavelength, there is a synchronous rising edge output in the trigger output signal 1, and at the beginning of the first wavelength of each cycle, there is a synchronous rising edge output in the trigger output signal 2. In this way, the receiving end starts the counter at the rising edge of the trigger output signal 2, and counts the number of trigger output signals 1. The wavelength information can be easily obtained based on the starting wavelength and step information, which is convenient and accurate.
