Abstract
A temperature detector configured for use in a mobile terminal includes a lens, a collimator hole, and an infrared sensor that are arranged on an optical path. The lens is configured to converge ambient light, and the ambient light includes target area light and another area light. The collimator hole is used to obtain the target area light by screening and block the other area light. That is, the collimator hole screens the incident ambient light, and allows only the target area light to reach the infrared sensor.
