论文摘要
提出了一个简单且低成本的激光互锁，该互锁是通过ESP32微控制器发出的软件命令操作的。构建设备的架构是为了确保在互锁信号线上从激光外壳或设备失功的互锁信号线路上关闭激光输出。通过否决局部控件（例如键盘），可以防止对激光束的无意接触，直到重新连锁封口并积极介入。呈现的设备旨在关闭光谱物体千年Pro Pulp Laser的机械快门，同时它继续在内部运行。硬件和编码的用途足够多，可以部署在通过串行接口接收软件命令的任何仪器上。
A simple and low-cost laser interlock is presented that operates via software commands issued by an ESP32 microcontroller. The architecture of the device is constructed to ensure the laser output is shut off in the event of either an open circuit on the interlock signal line from the laser enclosure or loss of power to the device. Unintentional exposure to the laser beam is prevented by overruling local controls (such as a keypad), until both the enclosure is re-interlocked and the user actively intervenes. The device presented is designed to close the mechanical shutter of a Spectra-Physics Millennia Pro pump laser while it continues to operate internally. The hardware and coding are versatile enough to be deployed on any instrument that receives software commands via a serial interface.
