Abstract
An optical detection device and a detection method thereof are provided. A linear light source provides a light curtain formed by multiple light beams, the light curtain is located on a transportation path of transporting an object to be detected. A sensor set senses the part of light beams not interrupted by the object to be detected, so as to generate a sensing signal with various strengths. A control circuit determines a physical characteristic, moving speed and position of the object to be detected according to the strength of the sensing signal.
