Problems solved by technology

However, this type of equipment cannot completely eliminate the possibility of laser irradiation on the human body. For example, if the laser encounters a mirror reflection device, it may still be reflected to human tissue, which may cause personal injury

Abstract

The present invention discloses a laser safety protection interlocking device and method. The laser safety protection interlocking device includes a housing as well as a laser capable of emitting laser and a laser outgoing interlocking circuit which are arranged in the housing; the housing comprises a door that can be opened and closed; when the door is in a closed state, the housing defines a sealed space, and the laser is located in the sealed space; and the laser outgoing interlocking circuit is configured to control the laser to automatically stop emitting laser when the door of the laser safety protection interlocking device is opened or before the door is opened.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a laser safety protection interlocking device and method. Background technique [0002] In a device using a laser, it is necessary to prevent the laser from being emitted into an environment where the human body may be exposed to the laser, so as to avoid the damage of the laser to the human body. [0003] Part of the existing laser equipment uses a plug-in or rotating laser lock or a mechanism similar to an emergency stop button to turn on or off the laser light-emitting enablement. However, the time at which this type of device stops emitting light is entirely dependent on the timing of the operator's actions. When the incident of laser irradiation on the human body takes place, this scheme cannot immediately and automatically cut off the laser light source. [0004] There are also some laser equipment that use laser baffles to avoid direct laser light on human ti...
