  • Publication number: 20200150266
    Abstract: A method for imaging objects includes illuminating an object with a light source of an imaging device, and receiving an illumination field reflected by the object. An aperture field that intercepts a pupil of the imaging device is an optical propagation of the illumination field at an aperture plane. The method includes receiving a portion of the aperture field onto a camera sensor, and receiving a sensor field of optical intensity. The method also includes iteratively centering the camera focus along the Fourier plane at different locations to produce a series of sensor fields and stitching together the sensor fields in the Fourier domain to generate an image. The method also includes determining a plurality of phase information for each sensor field in the series of sensor fields, applying the plurality of phase information to the image, receiving a plurality of illumination fields reflected by the object, and denoising the intensity of plurality of illumination fields using Fourier ptychography.

  • Patent number: 9958694
    Abstract: A minimized-thickness angular scanner of electromagnetic radiation includes an optical sandwich having a two-dimensional (2D) image source, and a scanning assembly that includes a first optic and a second optic, wherein at least one of the first optic and the second optic are oscillatorily translating. Translation of the optics provides for generation of a three-dimensional (3D) image, while the optical sandwich design provides for compact implementation of 3D displays.
