BORESIGHT ADJUSTMENT DEVICE AND METHOD OF RETRACING LIGHT PATH

摘要

PROBLEM TO BE SOLVED: To provide a boresight adjustment device which allows for preventing adverse effect of invisible laser light on human body, including retinal damage.;SOLUTION: A boresight adjustment device 70 is installed on a light transmitting window through which invisible laser light is emitted. The boresight adjustment device 70 comprises; a light path measurement unit 71 which has an array sensor 71a configured to receive the invisible laser light emitted through the light transmitting window and composed of a plurality of optical sensors arranged in an array, and is configured to derive a light path of the invisible laser light based on an output level of the array sensor 71a; and a light path retracing unit 72 configured to retrace the light path of the invisible laser light derived by the light path measurement unit 71 using visible laser light.;SELECTED DRAWING: Figure 18;COPYRIGHT: (C)2019,JPO&INPIT
