Light is allowed to travel through the optical enhancement assembly and into the aperture of the image-capturing device such that the light can be recorded as a still image or video. The optical enhancement assembly includes at least a unique fractalized diffraction pattern that impacts light traveling into the aperture and causes a unique diffraction effect on the image or video recorded by the image-capturing device.Type: GrantFiled: February 13, 2017Date of Patent: February 27, 2018Inventor: Connor W.

Patent number: 9880390Abstract: There is disclosed a novel system and method for improving spectral resolution and signal-to-noise ratio of a captured spectrum by employing digital beam reforming, digital slicing, and digital multiplexing. In an embodiment, the method comprises: and entrance aperture for the light to enter the apparatus, a collimating element (refractive or reflective), a dispersive element (single- or multi-axis), a focusing element (refractive or reflective), and a linear or array detector for acquisition of the spectrum. The spectrum is then digitally beam reformed, digitally beam sliced to increase spectral resolution, and digitally beam multiplexed to increase the signal-to-noise ratio. In addition the disclosed invention is also capable of performing digital beam refocusing which means the optical focusing power can be chosen such that its performance surpasses the performance of any analog optical focusing element thereby further increasing the spectral resolution and the signal-to-noise ratio of the spectrum.Type: GrantFiled: July 26, 2016Date of Patent: January 30, 2018Inventors: Alexander Sheung Lai Wong, Farnoud Kazemzadeh

Patent number: 9874319Abstract: 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: GrantFiled: January 27, 2017Date of Patent: January 23, 2018Assignee: MTT Innovation IncorporatedInventors: Johannes Minor, Gerwin Damberg, Raveen Kumaran, Anders Ballestad, Eric Jan Kozak, Gil Rosenfeld, Eran Elizur
