| description | A transceiver optical system (120), a lidar (100), a terminal device, a method, and an apparatus are provided, to suppress a stray light signal in the optical field. The transceiver optical system (120) includes a first emitter optical system (121) and a first receiver optical system (122). An optical axis (L11) of the first emitter optical system (121) and an optical axis (L13) of the first receiver optical system (122) have a specific included angle (α), so that an echo signal transmitted into the first receiver optical system (122) and the optical axis (L13) of the first receiver optical system (122) also have a specific included angle. In this way, a stray light signal is transferred by using the included angle (α), so that the stray light signal is effectively suppressed. In addition, effect of suppressing the stray light signal can be achieved by setting the specific included angle (α) between the optical axis (L13) of the first receiver optical system (122) and the optical axis (L11) of the first emitter optical system (121), and structural complexity of the first receiver optical system (122) and the first emitter optical system (121) may not be affected. This is easy to implement. |
