Publication number: 20210254797Abstract: A light source includes a plurality of laser diodes or other light emitters. Beams of light from the light emitters are steered to provide n array of parallel beams that illuminate a target area with an array of patches of light. In some embodiments the parallel beams are de-magnified to form the array of patches of light. Such a light source has application in illuminating dynamically-addressable focusing elements such as phase modulators, deformable mirrors and dynamically addressable lenses. Light projectors for a wide variety of applications may combine a light source as described herein with a dynamically-addressable focusing element to project defined patterns of light.Type: ApplicationFiled: February 25, 2021Publication date: August 19, 2021Inventors: Johannes MINOR, Gerwin DAMBERG, Raveen KUMARAN, Anders BALLESTAD, Eric Jan KOZAK, Gil ROSENFELD, Eran ELIZUR

Patent number: 10942428Abstract: A free-form lens (for example a phase modulator, lens or deformable mirror) may be made to reproduce a light pattern specified by image data. Source regions on the free-form lens are mapped to target regions areas on an image. Areas of the source regions are adjusted to vary the amount of light delivered to each of the target regions. Adjustment of the source areas may be achieved using a L-BFGS optimization which preferably incorporates smoothness and curl regularizers. Embodiments apply parallel processing to obtain control values for a free form lens in real time or near real time. Apparatus may process image data and display an image by controlling a dynamically variable free form lens using the processed image data.Type: GrantFiled: June 17, 2019Date of Patent: March 9, 2021Assignee: MTT Innovation IncorporatedInventors: Gerwin Damberg, Anders Ballestad, Raveen Kumaran, James Gregson

Patent number: 10477170Abstract: Undesirably high energy-consumption in illuminating devices can be caused at least in part by wasted (attenuated) light. Optically efficient illumination systems that may be used to project light, including images, use light redirection. Phase modulating devices may be applied to create desired light fields. Some embodiments provide dual or multiple modulation display or projection systems in which some or all of the modulators not only attenuate amplitude, but also amplify amplitude, or change the phase, frequency and polarization of the light provided by the light source.Type: GrantFiled: October 20, 2014Date of Patent: November 12, 2019Assignee: MTT Innovation IncorporatedInventors: Gerwin Damberg, Anders Ballestad

Patent number: 10255879Abstract: Image data is transformed for display on a target display. A sigmoidal transfer function provides a free parameter controlling min-tone contrast. The transfer function may be dynamically adjusted to accommodate changing ambient lighting conditions. The transformation may be selected so as to automatically adapt image data for display on a target display in a way that substantially preserves creative intent embodied in the image data. The image data may be video data.Type: GrantFiled: February 22, 2018Date of Patent: April 9, 2019Assignee: Dolby Laboratories Licensing CorporationInventors: Anders Ballestad, Andrey Kostin
