Abstract
There is provided an apparatus () for measuring a distance to a target (), comprising: a transmitter () configured to transmit an optical pulse () towards the target (), a receiver channel () configured to receive the optical pulse () reflected from the target (), and a processor () configured to measure a time intervaf between the transmission and detection of the optical pulse () at a predefined amplitude threshold level (OA,B), to determine a time domain parameter from the detected optical pulse () at one or more amplitude threshold levels (A,B), to convert the time domain parameter value into a correction value by a conversion model; to correct a timing error in the measured time interval by the correction value, and to convert the error-corrected time interval into a distance to the target ().
