摘要:
Systems and methods include optics having one or more phase modifying elements that modify wavefront phase to introduce image attributes into an optical image. A detector converts the optical image to electronic data while maintaining the image attributes. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets, and independently processes the data sets to form processed electronic data. The processing may optionally be nonlinear. Other imaging systems and methods include optics having one or more phase modifying elements that modify wavefront phase to form an optical image. A detector generates electronic data having one or more image attributes that are dependent on characteristics of the phase modifying elements and/or the detector. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets and independently processes the data sets to form processed electronic data.

摘要:
A system, method and software product to optimize optical and/or digital system designs. An optical model of the optical system design is generated. A digital model of the digital system design is generated. Simulated output of the optical and digital models is analyzed to produce a score. The score is processed to determine whether the simulated output achieves one or more goals. One or more properties of at least one of the optical model and the digital model is modified if the goals are not achieved. The analyzing, processing and modifying is repeated until the goals are achieved, and an optimized optical system design and optimized digital system design are generated from the optical and digital models.
摘要:
A method for reducing optical distortion within an optical system employing adaptive optics, includes modifying phase of a wavefront of the optical system with a wavefront coding element. Image data of the optical system is post-processed to remove phase effects induced by the wavefront coding element, to reduce optical distortion caused by the adaptive optics and associated with one or more of quilting, stuck actuator and piston error.

Low height imaging systems may include one or more optical channels and a detector array. Each of the optical channels may be associated with one or more detectors of the array, have one or more optical components and a restrictive ray corrector, and be configured to direct steeper incident angle field rays onto the detectors. Alternatively, each of the optical channels may be associated with at least one detector, and have an aspheric GRIN lens. Another low height imaging system has an array of detectors and a GRIN lens having a surface with wavefront coding and configured to direct steeper incident angle field rays onto more than one of the detectors. One method forms a lens with wavefront coding. The method includes positioning a lens in a mold; and curing material onto a surface of the lens to form an aspheric surface of the lens with wavefront coding.
摘要:
An imaging system for reducing aberrations from an intervening medium, and an associated method of use are provided. The system may be an optical or task-based optical imaging system including optics, such as a phase mask, for imaging a wavefront of the system to an intermediate image and modifying phase of the wavefront such that an optical transfer function of the system is substantially invariant to focus-related aberrations from the medium. A detector detects the intermediate image, which is further processed by a decoder, removing phase effects from the optics and forming a final image substantially clear of the aberrations. Other systems may employ an encoder that codes wavefronts of acoustical waves propagating through a medium to make the wavefronts substantially invariant to acoustical aberrations from the medium. Imaging and decoding of the wavefronts reverse effects of the wavefront coding and produce sounds substantially free of the aberrations.
摘要:
An eyewear device including an eye tracker to track a user's eye. The eyewear includes a see-through display for creating an image. The eyewear includes a light source generating a collimated light beam, and the display includes a powered optical element that receives and reflects the light beam. The powered optical element spreads the light beam to uniformly illuminate a user's eye. The powered optical element may include a holographic element.
摘要:
Eyewear having an optical waveguide communicating infrared light from a remote infrared emitter in the eyewear to an optical output coupler that uniformly illuminates an eye for tracking eye movement of a user. An optical input coupler couples a light beam emitted by the remote infrared emitter into the waveguide. The remote infrared emitter simplifies industrial design and is a single light source. The remote infrared emitter is not in a peripheral vision of a user's eye and improves a cosmetic impact.
摘要:
An electronic eyewear device with a shape memory alloy (SMA) actuator to apply torque to the eyewear temples. The torque presses the eyewear temples against the side of a user's head for a snug and comfortable fit. The SMA actuator allows one size of eyewear frames to fit a larger range of users, thereby reducing the number of sizes required to be manufactured for the electronic eyewear device.
摘要:
A see-through display including a polarized reflective pinhole mirror display. The pinhole mirror display includes a plurality of tiny switchable polarized mirrors. The respective polarized mirrors individually reflect impinging light from an illuminator, and guide the respective portion of light into a pupil of an eye. A reflective optically powered surface reflects light from the illuminator. Each mirror has a first polarization and reflects a portion of light and produces a picture element (pixel) that forms a virtual image seen by the eye of the user. A user may view the reflected virtual image having the first polarization from the illuminator, as well as the image from the real world via a rear substrate that has a second polarization. Although the mirrors are very small, human eyes can still detect the mirrors if they are not polarized. The mirrors and other components are polarized so that the eye can see the real world filtered with the second polarization, but not the mirrors having a different first polarization.
