Abstract

The invention relates to a synchronous multiplex pulse generating system and a method. The system comprises a communication module used for receiving a command frame and sending the command frame to an FPGA module, an FPGA module used for generating synchronous pulse signals with long time-delay time according to the command frame, and a CMOS analog time-delay module used for generating synchronous pulse signals with short time-delay time according to the command frame. According to the synchronous multiplex pulse generating system and the method, nanosecond time-delay adjustment is performed via the FPGA module, and picosecond time-delay adjustment is performed via the CMOS analog time-delay module so that synchronous pulse with high time-delay precision and wide time-delay time range is generated, the size and the cost of the pulse generating system are reduced, the universality of the pulse generating system is greatly improved, and the system and the method are advantaged by simple operation, low cost, and easy promotion.

Description

technical field [0001] The invention relates to the field of pulse generation, in particular to a synchronous multi-channel pulse generation system and method. Background technique [0002] With the development of optoelectronic technology, the application of synchronous signal is more and more extensive, and it is applied in various instruments and equipment and industrial sites. High-precision (ps level) delayers are required in many applications such as 3D pulsed laser ranging, single-photon secure communication, and laser confinement fusion control. For example, the distance accuracy of 1cm in the 3D pulsed laser ranging system requires the delay of the delayer to reach an ultra-high precision of less than 60ps. In the fields of industrial site control and analytical instruments, the requirements for delay accuracy of synchronous pulses are relatively low. For example, in the laser beam breakdown spectroscopy system, the signal collector must be delayed for a period of...
