Popis: | A laser beam with a pseudo random bit stream pattern amplitude modulation is retro reflected off a target to produce a real time ranging signal using a cross correlation technique. The measured resolution of the system was 0.2 mm with an absolute accuracy of ± 2 mm over 2 m. The use of a modulated retro reflector allows a communications signal to be added to the ranging capability. |
