Gyroscope, electronic device and method of detecting angular velocity

An electronic device, comprising a gyroscope,

• wherein the gyroscope comprises:
• a photoelectric detector and a light source,
• the light source is movable relative to the photoelectric detector, and light emitted by the light source is able to be irradiated onto the photoelectric detector,
• wherein the light source is a polarization light source;
• the gyroscope further comprises a polarization analyzer for polarization light;
• wherein the polarization light source is movable relative to the polarization analyzer for polarization light, and polarization light emitted by the polarization light source is able to be irradiated onto the photoelectric detector through the polarization analyzer for polarization light.

A method of detecting an angular velocity, comprising:

• allowing a light source that is movable to perform an angular movement with a motion state of a detected object;
• allowing light emitted by the light source to be irradiated onto a photoelectric detector, and allowing illumination areas irradiated onto the photoelectric detector in different motion states to be different;
• obtaining a detecting result provided by the photoelectric detector;
• and
• obtaining a change in intensity of the light irradiated onto the photoelectric detector from the detecting result to obtain the angular movement of the light source,
• wherein the light source is a polarization light source, and
• allowing the light emitted by the light source to be irradiated onto the photoelectric detector, and allowing illumination areas irradiated onto the photoelectric detector in different motion states to be different, comprises:
• allowing polarization light emitted by the polarization light source to be irradiated onto the photoelectric detector through the polarization analyzer for polarization light, and allowing intensity of the polarization light irradiated onto the photoelectric detector in different motion states to be different.
