| Zusammenfassung: | An optical activity detecting device is provided. The optical activity detecting device is adapted to detect an object. The optical activity detecting device includes a light source, a filter, a first polarizer, a second polarizer, a first compensation film and a first sensor. The light source provides a light beam. The light beam passes through the filter and the polarizer, and enters the object. At least a portion of the light beam travels from the object, passes through the second polarizer and the first compensation film, and is received by the first sensor. |
