Increasing Measurement Rate In Time Of Flight Measurement Apparatuses
Patent No. EP2233947 (titled "Increasing Measurement Rate In Time Of Flight Measurement Apparatuses") was filed by Leica Geosystems on Oct 6, 2006. The application was issued on Sep 17, 2014.
Patent Summary
An airborne time-of-flight measurement apparatus for terrain collection comprises a laser, an optical receiver, laser control circuitry, elapsed time circuitry, and a data processing device to calculate surface distance. The control circuitry triggers a first light pulse and a subsequent second pulse, transmitting the second pulse before the first pulse's reflection is received. The elapsed time circuitry measures the interval between transmission and reception for each pulse. An optional scanning subassembly directs pulses at different angles. To distinguish overlapping reflections, the laser circuitry approximates range gates—time intervals based on estimated distances where reflections are expected. The apparatus utilizes these range gates to differentiate between the incoming reflected portions of the first and second light pulses.
