<p>Apparatus (10) for range finding. The apparatus (10) comprises a laser source (T1) for emitting a high energy laser pulse (p(t)) towards a surface (22) to be investigated. A sensor (32) is employed for receiving a portion (p'(t)) of the laser pulse (p(t)) after it has been reflected at said surface (22). Means (33) perform an analog-to-digital conversion of the output signals (s'(t)) provided by the sensor (32) to obtain digital sensor data samples (sk). A sample storage (31) for storing a set of said sensor data samples is provided and a hardware control unit (30) for processing the set of said sensor data samples (sk) is employed. This processing is done by scanning the sensor data samples (sk) with generic pulse shapes which are allowed to vary continuously over one or more variation parameters.</p> |
