Abstract
The present application discloses a LiDAR and a movable device. The LiDAR includes an emission module, a receiving module, a beam splitter and a scanning module. The receiving lens meets 40 mm≤fRX≤80 mm, where fRX is the effective focal length of the receiving lens. The beam splitter includes a light transmitting portion and a reflecting portion, the reflecting portion being disposed at the periphery of the light transmitting portion. The scanning module is configured to emit the detected light to the target object, and to transmit the echo light to the receiving module.
Claims10
A LiDAR, comprising:
- an emission module, configured to emit detection light;
- a receiving module, configured to receive echo light formed by reflected detection light from a target object, wherein the receiving module comprises a receiving lens and a receiver, the receiving lens is located on a light-entry side of the receiver, the receiving lens satisfies a conditional formula:
