1. An optical sensor comprising:
a light source emitting signal light;
a light sensing element on a light emitting side of the light source and on an optical path of the signal light, the light sensing element being configured to receive ambient light, receive the signal light through one side, and transmit at least a part of the signal light as an incident light through another side, wherein a transmittance of the light sensing element changes according to an intensity of the ambient light and an intensity of the incident light transmitted from the light sensing element changes with the transmittance of the light sensing element; and
a photoelectric conversion element on a light transmitting side of the light sensing element away from the light source, the photoelectric conversion element being configured to receive the incident light from the light sensing element and output a voltage modulation signal according to the incident light, and the voltage modulation signal changes with the intensity of the incident light.
