A composite device of intelligent multifunctional laser protection goggles and automatic detection and alarm is designed and developed, which is mainly used for protection and early warning of human eye damage caused by laser radiation. The protection spectacles, detection and alarm system and intelligent composite protective technology are studied. The laser protection and detection and alarm performance of the composite device are tested. The signal interconnection and linkage between the protection spectacles and alarm device are used to combine the protection spectacles’ double spectacles and send alarm signals. The results show that when the laser protection alarm compound device detects the laser irriadiation, it can send out various alarm signals and compound protection response in different ways, including flashing lights of different colors, sound and vibration alarms, and drive the two protection spectacles to recombine. It can effectively protect human eyes from laser of specific wavelengths (532 nm, 1 064 nm, 470 nm, 808 nm and 700-2 000 nm) as well as from supercontinuum laser, and realize cluster linkage alarm and protection through wireless signal interconnection. The laser protection spectacles and detection and alarm composite device has the characteristics of intelligent, modular and multifunctional integration, and its performance meets the design requirements
