Abstract: A terminal includes a camera, a laser transceiver, a protection glass, and an infrared cut-off coating. The camera includes an image sensor and N lenses; the image sensor is disposed at the rear of the N lenses, and is configured to: receive an optical signal penetrating the protection glass and the N lenses, and convert the optical signal into an electrical signal. The protection glass is disposed in front of the N lenses, and is configured to protect the N lenses. The laser transceiver is configured to transmit or receive a laser. The infrared cut-off coating is located on at least one surface of the protection glass and/or on at least one surface of at least one lens in the N lenses, and a cut-off wavelength of the infrared cut-off coating is corresponding to a center wavelength of the laser transmitted by the laser transceiver.
