Ranging apparatus and mobile platform

A mobile platform comprising:

• a platform body;
• and
• a ranging apparatus arranged at the platform body and including:
• an emitter configured to emit a light pulse sequence;
• and
• a detector configured to receive and convert a portion of return light reflected by an object into an electrical signal and determine at least one of a distance or an orientation of the object relative to the ranging apparatus according to the electrical signal;
• wherein:
• at least one of an anti-reflection material or a reflective surface with a predetermined inclined angle is arranged at a non-working surface off an emission optical path of the light pulse sequence and a reception optical path of the return light and is configured to reflect stray light to outside of the detector;
• and
• the non-working surface includes a surface of the ranging apparatus that the light pulse sequence and the return light do not pass through.
