    • Light curtain comprising two long assemblies defining between them an area to be monitored.Each assembly P1, P2 comprises with regard to the other assembly a striped surface of light 13 and dark areas 12 thus forming a grid. A linear or matrix receiver having a suitable optic picks up the image from the grid and the processing means of the two assemblies process the corresponding image signals to send an intrusion signal. Each assembly should preferably have two receivers RH1, RB1; RH2, RB2 near its ends and the optic associated to each receiver should cover the whole length of the opposite assembly, and the processing means should carry out a redundant processing of the images of the monitored area.
    • 光幕包括两个长的组件,在它们之间限定要监视的区域。每个组件P1,P2包括关于另一个组件的条纹表面13和暗区域12,从而形成网格。 具有合适光学器件的线性或矩阵接收器从网格拾取图像,并且两个组件的处理装置处理相应的图像信号以发送入侵信号。 每个组件应优选具有两个接收器RH1,RB1; RH2,靠近其端部的RB2和与每个接收器相关联的光学器件应覆盖相对组件的整个长度,并且处理装置应对被监视区域的图像进行冗余处理。
