1. A light emitter and receiver module, comprising:
a light emitter module configured to emit a detection beam; and
a light receiver module configured to receive an echo beam of the detection beam reflected by a target object, wherein:
the light receiver module is configured to convert the echo beam into an electrical signal; and
a field of view of the light emitter module configured to overlap vertically with a field of view of the light receiver module; and
wherein:
in a first direction, a size of the field of view of the light emitter module is larger than a size of the field of view of the light receiver module; and
in a second direction perpendicular to the first direction, a size of the field of view of the light emitter module is smaller than a size of the field of view of the light receiver module;
wherein the light emitter module comprises:
a plurality of light emitter units, each comprising a plurality of light emitter points;
the plurality of light emitter units share a common cathode or a common anode; and
each light emitter unit has a connection point which is electrically connected to unshared anode or cathode of the corresponding light emitter unit; and
wherein the light receiver module comprises:
a plurality of detector units, each comprising a detecting region and a connection point; and
at least one detector unit and one light emitter unit form a detection channel.
