Broadband interferometric confocal microscopy using interference objectives in combination with a synthetic phase modulation.
Background Broadband interferometric microscopy (BIM) refers to microscopy techniques and methods that use the frequency of light and interferometric detection to infer the volumetric spatial structure of the scattering object. The goal is to achieve three-dimensional imaging with high resolution over large fields of view and extended depths. The interference...

Enhanced Contrast Imaging Using DMD Array as Confocal Filter
Background Traditionally, confocal imaging strategies use a small pinhole aperture at the imaging plane to reject scattered light and light that is out of focus from the optical plane of best focus. We describe a new imaging detection scheme that incorporates a digital micromirror device (DMD) at the imaging plane to provide a fast dynamic “synthetic...

Multispectral Imaging CMOS Sensor
ProblemMultipixel image sensors are widely used in digital camera, LIDAR, medical imaging devices, and other equipment. For color image sensors, typically arrays of pixel elements are used for each pixel position. Light reaches each pixel element through a respective color filter, so each pixel element responds primarily to a single color, for example...

Telecentric and Broadband Achromatic Objective Lens Systems and Method of Use in Optical Coherence Tomography for the Metrology of Freeform Optical Components
ProblemThe application of optical coherence tomography for the metrology of freeform optical components requires objective lens systems that are highly telecentric and broadband achromatic.SolutionTo meet these requirements, two new objective lens designs are invented: a large field-of-view objective, and a large numerical aperture objective. Specifications...

Gravitational Camera
This technology describes how a gravimeter may be used as an gravitational imaging device. The pendulum gravimeter may include an interferometer, such as a Sagnac interferometer, to determine a displacement on the pendulum by way of a mirror attached to the pendulum. Scanning of the object may be performed in 1D, 2D, or 3D, and may result in an image...

Freeform and Nanostructured Surfaces Based Augmented Reality Sunglass Display
A near eye display includes at least one of a combiner, a secondary mirror, and a waveguide having a freeform nanostructured surface. The freeform nanostructured surface encompasses a freeform surface, a nanostructured surface or a combination of both the freeform surface and the nanostructured surface. The freeform nanostructured surface can be incorporated...
