LIGHT SOURCE TRACKING SENSOR UNIT CAPABLE OF MINIMIZING AN ERROR CAUSED BY PERIPHERAL SCATTERED LIGHT OR SECONDARY LIGHT SOURCE

摘要

PURPOSE: A light source tracking sensor unit is provided to improve the accuracy of sensing a target light source by preventing scattered light reflected off peripheral structures or lights emitted from a secondary light source from entering an optical sensor.;CONSTITUTION: A light source tracking sensor unit(10) comprises an optical sensor(30) which detects lights emitted from a light source and a light guide unit(40) which is installed in the optical sensor and allows only the light that enters the optical sensor in a specific direction to reach the optical sensor.;COPYRIGHT KIPO 2012
