Abstract: A ranging system and a mobile platform are provided. The ranging system includes a laser (6031), a coaxial optical lens group, a mirror group (602), a moving component, and a processing circuit. When the laser (6031) emits laser light to the mirror group (602) by using the coaxial optical lens group, the moving component drives the mirror group (602) to rotate, so that the laser light is irradiated to a measured object at different angles, to implement ranging of the measured object. The moving component bears a light object, so that the moving component rotates quickly. Therefore, if the ranging system is installed on a vehicle, the ranging system can implement fast ranging of incoming and outgoing vehicles and meet a ranging requirement of an autonomous driving technology. In addition, an optical path of the laser light and an optical path of reflected light are designed coaxially. This design can reduce an area required by a mirror in a mirror group, and further reduce a volume of the ranging system, thereby facilitating miniaturization of the ranging system.

IPC: G11B7/0065
Filed: 2020-01-10
Abstract: The effective coherence length of a single-frequency, solid-state laser is limited to reduce spurious, secondary holograms in conjunction with a holographic recording. The wavelength of the laser is varied or 'scanned' with high precision over a very small wavelength range. In an embodiment, the temperature of the laser's resonant cavity optical bench is altered, causing the dimension of the cavity to change and the emission wavelength to move in a controlled manner. The changing wavelength is monitored at high resolution, and a feedback control loop updates the temperature set-point to keep the monitored laser wavelength moving at a desired rate of change through a desired range. As the wavelength of the laser is scanned, the phase of the holographic interference pattern is locked at a position of maximum coherence/contrast within the holographic film aperture.
