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...

Absolute Linear-in-K Spectrometer Using Freeform Optics
We present an optical design method and solutions of linear-in-k spectrometers exhibiting extremely low residual nonlinearity (< 10E-4%) made possible by the inclusion of a freeform optics. Previous work in the literature shows that hardware-based solutions for k-linearization by adding a prism after the grating have residual non-linearity. The merit...

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...

Hand Held X-Ray Receptor
The present invention is a portable cadmium zinc telluride (CZT), imaging system. It is comprised of a radiation source, a novel sensing mitt (detector), that can be worn or held by the user and a collimator. The collimator is placed in front of the sensing surface of the CZT crystal and a processor converts a representation of the electrical signals,...
