Abstract
An optical system and a method for eliminating misjudgment of reflective lights are provided. The method includes: emitting a detection light by a light source; receiving reflective light signals by a light sensor; and configuring a processing circuit to: generate a characteristic pattern according to the reflective light signals received by the light sensor; analyze the characteristic pattern and determine whether or not the characteristic pattern includes a plurality of sub-patterns; in response to determining that the characteristic pattern includes the plurality of sub-patterns, compare positions of the sub-patterns with a reference position of a reference pattern; and select the sub-pattern having the position that is closest to the reference position to determine whether an object is present in a detection range and eliminate misjudgment caused by the reflective lights.
