1. A receiver for a light detection and ranging (LIDAR) system, the receiver comprising:
a plurality of detecting elements, each detecting element comprising one or more members configured to convert light into an electric signal, each detecting element configured to generate an analog detection signal in response to a laser pulse emitted by a transmitter of the LIDAR system;
a first converting element configured to generate a first digital detection signal in response to a first analog detection signal provided by at least a first one of the plurality of detecting elements, wherein the first converting element is configured to generate the first digital detection signal having a first number of bits that represent the first analog detection signal;
a second converting element configured to generate a second digital detection signal in response to a second analog detection signal provided by at least a second one of the plurality of detecting elements, wherein the second converting element is configured to generate the second digital detection signal having a second number of bits that represent the second analog detection signal, the second number of bits being greater than the first number of bits, wherein the first one of the plurality of detecting elements and the second one of the plurality of detecting elements are same or different detecting elements; and
at least one processor configured to determine at least a first parameter of an object in a target area of the LIDAR system using the first digital detection signal and determine a second parameter of the object using the second digital detection signal.
