    • The present invention relates to a laser interlock system that allows laser radiation to be generated when an inspector and a subject correctly wear safety glasses during use of a photo-acoustic imaging apparatus, thereby protecting the eyes of the inspector and the subject and preventing unnecessary power consumption. The laser interlock system includes a sensing unit to sense whether or not contact between a user and safety glasses occurs, a light source unit to generate laser radiation, and a control unit that determines, based on an output value from the sensing unit, whether or not the user is wearing the safety glasses, and generates an interlock signal to turn on or off the light source unit for selective laser generation according to the determination.
      The sensing unit further includes a left measurement unit and a right measurement unit, wherein the control unit determines whether or not the user wears the safety glasses based on if each of the output values of the left measurement unit and the right measurement unit exceeds a preset first threshold value.
    • 激光联锁系统技术领域本发明涉及一种激光联锁系统,其允许在光电成像设备的使用期间检查者和被检者正确佩戴安全眼镜时产生激光辐射,由此保护检查者和被检者的眼睛并防止不必要的电力 消费。 激光联锁系统包括:感测单元,感测用户与安全眼镜之间是否发生接触;光源单元,产生激光辐射;以及控制单元,基于来自感测单元的输出值确定是否或者 而不是用户佩戴安全眼镜,并且根据该确定生成互锁信号以开启或关闭光源单元以用于选择性激光生成。 感测单元还包括左测量单元和右测量单元,其中,控制单元基于左测量单元和右测量单元的输出值中的每一个是否超过预设值来确定用户是否佩戴安全眼镜 第一阈值。
