When the vibration direction of the incident light is a fixed direction and the driving mechanism 030 rotates the polarizing plate 040, the light flux of the light passing through the polarizing plate 040 changes according to the angle at which the polarizing plate 040 rotates.

For example, the light emitted by the light source is visible light and infrared light, the first filter 020 is an infrared light filter, the second filter 050 is a visible light filter, the filter to be identified 010 is a visible light filter, and the light flux data of the current light source is 100, then the light flux of the infrared light passing through the first image is 100 × 99% × 1% approximately equal to 0.99, and the light flux of the visible light passing through the first image is 100 × 1% × 99% approximately equal to 0.99; the luminous flux of the infrared light passing through the second image is 100 × 99% × 99% ≈ 98.01, and the luminous flux of the visible light passing through the second image is 100 × 1% × 1% ≈ 0.01, and in consideration of an error range and the like, the first preset parameter may be set to 1.5, the second preset parameter may be set to 90, and optionally, the height of the luminous flux data may also be set to a percentage threshold.
