Abstract
A range finder includes a plurality of modulated seed lasers providing light at different wavelengths. Light from the seed lasers is provided to a wideband laser fiber amplifier. A portion of amplified laser light is directed to a first detector. The remainder is transmitted to a target through a collimating lens. Reflections from the target are received by a telescope. A major portion of the returned light is provided to a second detector. A minor portion is provided as feedback to the wideband laser fiber amplifier for stabilization. Outputs from the first and second detector are provided to a processor. Processor analyzes the time delay between the transmitted light and the reflected light to provide a range output. Other embodiments could use adaptive optics and mode hopping range calculations.
