Abstract: An example system includes a master oscillator that provides a master oscillator beam, a first fiber beam splitter that splits the master oscillator beam into a first branch and a second branch, a second fiber beam splitter that splits the first branch into an imaging branch and an amplified characteristic branch, and a compensation branch mixer that mixes the second branch and the amplified characteristic branch into a compensation branch. The example system includes transmission optics that direct the imaging branch to a target location, an imaging mixer that mixes the compensation branch and a reflected image from the target location into an imaging signal, and an acquisition device that receives the imaging signal as a final image. An example system optionally includes a mode matching lens that applies a selected wavefront characteristic to the compensation branch.

Abstract: A multi-function, range-Doppler, synthetic aperture and micro-Doppler, coherent laser radar system having improved spatial resolution and immunity to undesired platform motion utilizing two or more simultaneous, spatially offset transceiver apertures.

Abstract: A stationary Fourier transform spectrometer is described which includes an interferometer including a substantially solid assembly of a beamsplitter, two right angle prisms and a pentaprism of preselected respective aperture sizes, a radiation source, a Fourier transform lens and an optical detector.
