变形镜驱动器控制电路的设计
Design of control circuit for deformable mirror driver
摘要
Abstract
The 96-channel deformable mirror driver includes 6 driver modules,and each module has 16 output channels. In order to manage the 6 driver modules more efficiently,and realize the interactive communication with the upper computer and image processing module,a control circuit of the deformable mirror driver was designed. The hardware design and software design of the circuit are introduced. The hardware design contains the power supply design,interface design and FPGA design, which can transmit the driving vector data from SPI to CPCI bus in high speed,and send the data to the upper computer with proper speed. The software design includes the FPGA program design and NIOS system program design. The NIOS program is used to receive,process and send the instructions or data of the upper computer,configure the system parameters,and save the parameters of the driving module. The experimental results show that the circuit can accurately receive and send the driving vec-tor data from the image processing module with the speed of 200 f/s,correctly transmit and receive the control instructions from the network interface or serial port of the upper computer,and realize the switchover between the single channel and driving vec-tor,switchover between the driving vector data,voltage set of single channel,amplifier parameter debugging and saving,read and postback of the channel data. It achieves the scheduled design target.关键词
