Abstract: A transceiver optical system is configured to suppress a stray light signal in the optical field. The transceiver optical system includes a first emitter optical system and a first receiver optical system. An optical axis of the first emitter optical system and an optical axis of the first receiver optical system have a specific included angle (α), so that an echo signal transmitted into the first receiver optical system and the optical axis of the first receiver optical system also have a specific included angle.

Abstract: A detection system, a terminal device, and a detection control method are provided, to resolve a problem of low detection accuracy of a detection system in the conventional technology, and are used in fields such as autonomous driving, intelligent driving, assisted driving, or networked vehicles. The detection system includes a transmit module, a receive module, a first scanning module, and a second scanning module. An included angle between a first normal vector of a first reflective surface of the first scanning module and a second normal vector of a second reflective surface of the second scanning module is a first angle greater than 0 degrees. The first reflective surface and the second reflective surface are adjacent reflective surfaces. An included angle between an optical axis of the transmit module and an optical axis of the receive module is a second angle greater than 0 degrees.
