Laser beam projection system with dynamic phase compensation
Publication/Patent Number: US10401499B2 Publication Date: 2019-09-03 Application Number: 15/072,214 Filing Date: 2016-03-16 Inventor: Marron joseph   Halmos, Maurice J.   Grayer, Justin S.   Erten, Gamze   Sitter, Jr. David N.   Assignee: Raytheon Company   IPC: H04N7/18 Abstract: A laser beam projection system builds on a coherent imaging to project a tightly focused laser beam onto a remote object. Coherent flood illumination and local oscillator (LO) illumination are based on one master oscillator. The coherent flood illumination is directed toward a remote object, with a second laser beam directed onto an aimpoint on the same object. A Doppler sensor provides Doppler shift data used to produce Doppler-shifted LO illumination received by a focal plane array, together with the return flood illumination. Interference between the Doppler-shifted LO illumination and the return flood illumination facilitates imaging the object despite the velocity. The wavefront error of the flood illumined remote object image is computed and compared to the desired wavefront of the second laser beam at the aimpoint, with the difference applied to a deformable mirror to shape the second laser beam wavefront for obtaining a desired aimpoint intensity profile.
