LASER REMOTE COMMAND SYSTEM AND TARGETS THEREFORE

The present invention relates to a laser irradiating device and a target device, and particularly to a laser irradiating device capable of performing remote control without using a radio remote controller. A plurality of reflective pattern members are prepared wherein combination reflective members respectively composed of reflective portions A for storing the direction of polarization and reflecting it, and polarizing-direction conversion reflective portions C for converting the direction of polarization and reflecting it are arranged. The combination reflective members of the individual reflective pattern members are respectively made different in arrangement from one another. Further, the reflective pattern member corresponding to a command to be transferred to the laser irradiating device reflects identification reflected light corresponding to the command onto the laser irradiating device, whereby the laser irradiating device can be remote-controlled.
