Description

technical field [0001] The invention relates to the generation of disordered pulses, in particular to a disordered pulse generation circuit for generating disordered pulses through a hardware circuit. [0002] Background technique [0003] In laser processing, when the disordered arrangement of laser spots and energy inhomogeneity are required, a disordered pulse generator is required to control the disordered laser pulse output interval and light output time to achieve the above goals. Therefore, the disordered pulse generator is required to have the function of making the frequency and duty cycle of each output pulse change disorderly. At present, many patents and documents talk about many methods of generating random numbers, such as CN201410112133 and CN201420183585. To achieve the above functions, most of them adopt control chips with a structure similar to microcontrollers, and realize by writing programs to adjust the period value and comparison value in the puls...
