  • Signal mirror
    Patent number: 5528421
    Abstract: A signal mirror includes an irradiation device for reflecting incident light by a same reflection function as a plane mirror and irradiating reflected light to an irradiation target; and an optical axis finding device including a sheet having at least a surface on an irradiation device side as a retroreflection face, for reflecting incident light incident on the sheet from the irradiation device side in an opposite direction to the irradiation target using retroreflection and reflection by the irradiation device, thereby ensuring finding of an optical axis of reflected light irradiated on the irradiation target by the irradiation device. The reflected light can be irradiated on the irradiation target by the irradiation device while the optical axis of the reflected light is found by the optical axis finding device.
