Optical Phantom for Producing a Time-Resolved Diffuse Reflectance Spectrum

Inventors

Jeeseong Hwang, Heidrun Wabnitz

Patent Description Physikalisch-Technische Bundesanstalt (PTB) and NIST jointly developed a concept for a waveform synthesizer which can generate a controlled waveform with several picosecond (ps) time resolution. In a light-diffusing material, characteristics of the time-of-flight distribution (e.g
The figure shows a microfabricated optical probe with the following components: 110 - optical loop, 111 – structured region of 110, 114 – optical waveguide, 116 – first arm of optical  waveguide, 120 – substrate, 122 – optical cladding layer, 124 – first single mode optical fiber, 126 – primary light, and 128 – output light.

Microfabricated Optical Probe

Inventors

Vladimir Aksyuk, Kartik Srinivasan, Thomas Michels

Patent Description Integrated photonics research and manufacturing requires a probe for in-line nondestructive optical testing of devices. Current optical probes require dedicated and large coupling areas in the photonic circuit. They cannot provide sufficient control over the degree, location and

Photonic probe for atomic force microscopy

Inventors

Marcelo Davanco, Vladimir Aksyuk

Patent Description Atomic force microscopy probes with integrated photonic optomechanical cavity readout are new and provide improved sensitivity, increased measurement speed and reduced measurement noise in a variety of research and manufacturing metrology applications. While such probes have been
This is a line drawing for patent number 10,625,470

3D Printing of Composition-Controlled Copolymers

Inventors

Jirun Sun, Young Lee

Patent Description This invention is a new 3D printing process of continuously or discretely controlling composition of photo-polymerization reactants to produce 3D objects with spatially varying chemical, physical and mechanical properties. This invention is based on photo­ polymerization of liquid

High Efficiency Photon Detection

Inventors

Rachel Cannara, Fred Sharifi, Alex Smolyanitsky

Patent Description A detection pixel includes a material that is chosen so that its (averaged) atomic number density leads to the Compton process being the dominant scattering mechanism in response to incident photons, leading to production of Compton electrons with sufficient number and kinetic
