  • Diffractive beam steering system with high efficiency
    Patent number: 12111557
    Abstract: Opto-mechanical assemblies, systems, devices and methods for pointing laser and other optical beams, and for directing the field of view of sensors are disclosed. The assemblies consist of thin rotating optical elements of a type that diffracts the optical beam over a wide field of regard in two dimensions, and the angle of incidence of the optical beam or line of sight impinging on the optical elements are dynamically controlled maximizing the diffraction efficiency of the optical elements.
