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 system includes an initiating optics layer interposed between an electromagnetic (EM) source and a lenslet steering layer, where the lenslet steering layer includes a first positive lens element and a second negative lens element. The lenslet steering layer is interposed between the initiating optics layer and a concluding optics layer. The system includes a steering controller configured to steer an EM beam from the EM source by controlling a first relative rotation between the first positive lens element and the second negative lens element, and further by controlling a second absolute rotation of the lenslet steering layer. The system includes a rotating actuator responsive to rotation commands from the steering controller, where the rotating actuator selectively rotates the first positive lens element and/or the second negative lens element.

Abstract: A system includes a ground-based area, an electromagnetic (EM) interrogation device having an EM emitter that directs an EM beam at the ground-based area. The EM interrogation device includes a detector array that receives reflected EM radiation from the EM beam, and a controller having a ground movement description module that determines a movement profile of the ground-based area in response to the reflected EM radiation.

Abstract: An example system includes a high-side electrode layer having a first number of electrical members alternated with, and electrically coupled to adjacent ones of a second number of electrical members, where either the first number of electrical members or the second number of electrical members are discrete electrodes, and the other one of the first or second number of electrical members are resistors. Accordingly, the high-side electrode layer is formed from alternating discrete electrodes and resistors. The example system further includes a low-side electrode layer, and an electro-optic (EO) layer having an EO active material at least partially positioned between the high-side electrode layer and the low-side electrode layer, thereby forming a number of active cells of the EO layer.

Abstract: This disclosure teaches a thin film beam steering system comprising either flat or tilted transparent electrodes on one side of the electro-optical crystal layer and a transparent ground electrode on the other side. There is an insulator between each adjacent electrode which can be inserted all the way or partially through the EO crystal layer. A mirror layer can also be attached to the ground electrode. The refractive index of the EO crystal layer is changeable as a function of varying an applied voltage generated by the voltage supply and applied to the EO crystal layer. The disclosure also includes bulk crystal beam steering systems to steer a beam in 2 dimensions and to a wider angle.
