Abstract:
1. A real-time space based planetary mapping measurement system for remote sensing and mapping comprising: one or more processors; an illumination source controller and modulator coupled to one or more processors; a cavity free real-time electronically adjustable wavelength pulsed illumination source with multipower multiple laser lines coupled to the illumination source controller and modulator; a receiver having a capability for detecting illumination transmitted by the illumination source and providing signals based on detected illumination; the pulsed illumination source comprising: a seed coupled to the illumination source controller and modulator and accepting control and modulation signals therefrom; and an optical amplifier having an input coupled to the seed and having an output, the optical amplifier comprising two or more gain sections coupled to form a continuous solid waveguide along a primary optical path, each gain section comprising: an optical isolator forming an input to that gain section; a doped optical fiber having a first end coupled to the optical isolator and having a second end; a plurality of pump laser diodes; a controller providing drive signals to each of the plurality of pump laser diodes, the controller being configured to provide at least pulsed drive signals; and an optical coupler having a first input port coupled to the second end, a second input port coupled to said plurality of pump laser diodes and an output port.
