Abstract
A laser sensor includes: a receiver array configured to convert received optical signals into electrical signals, wherein a noise floor of the electrical signals is positively correlated with temperature if environmental temperature is within a first preset temperature range, and negatively correlated with the temperature if the environmental temperature is within a second preset temperature range; a compensation module coupled with the receiver array and configured to receive the electrical signals, amplify the electrical signals with a first and a second amplification factors, respectively, when the environmental temperature is within the first and the second preset temperature ranges, wherein the first amplification factor is negatively correlated with the temperature and the second amplification factor is positively correlated with the temperature; and a processor coupled with the compensation module and configured to identify sensing signals based on the electrical signals amplified by the compensation module and the noise floor.
