Hi all, Has anyone worked on using either solid state laser diodes for ranging? If so, what type of detector did you use? How about ECL counters for measuring time of flight of laser pulse? Or how about using PSD for triangulation on a laser or infrared beam? This might seem like a dumb question, but, can a laser be built in the infrared range, and if so what is the difference between it and say an infrared diode? Is the laser a more concetrated beam? Any info is greatly appreciated. I'm trying to design lightweight, low power rangers, that will give ~ 2-3 meters range and ~4 cm accuracy. The sensors are for a mars rover prototype project. Thanks for your time, -- ++++++++++++++++---------------------------------+++++++++++++++++ Albert Behar (818)354-0741 behar@robotics.jpl.nasa.gov Mars Rover Project, Robotic Intelligence Group M/S 107-102 Jet Propulsion Laboratory, Pasadena, CA 91109
