Abstract
An optical system and a method of judging a category of an under-test object are provided. The optical system includes a reflective structured light generation element and a sense judgement device. The reflective structured light generation element is installed on an under-test object. After the light beams from a light source are received by the reflective structured light generation element, a structured light is generated and reflected to an under-test surface. Consequently, a test pattern is shown on the under-test surface. The sense judgement device is used for sensing the test pattern on the under-test surface, and judging a category of the under-test object according to the sensed test pattern. The use of the structured light to judge the category of the under-test object can achieve the anti-counterfeiting efficacy.
