Abstract:
A large area projection micro stereolithography (LAPuSL) system uses an addressable spatial light modulator (SLM) in coordination with an optical scanning system to make very large stereolithographically produced objects. The SLM is imaged onto a photosensitive material with an optical system that has the ability to scan the image over a large area and speedily manufacture large scale complex three dimensional components with micro scale features.

Application number: 17/613,477

Abstract:
Devices, systems and methods for performing X-ray scans with a single line of sight using a lens array for capturing the light field of the X-rays are described. In one example aspect, an X-ray optical system includes a primary optics subsection positioned to receive incoming X-rays after traversal through an object and to redirect the received incoming X-rays onto an intermediate image plane. The system also includes a microlens array positioned at or close to the intermediate image plane to receive at least some of the received incoming X-rays after redirection by the primary optics subsection to diffract the X-rays that are incident thereupon.

Application number: 17/529,249

Abstract:
The disclosed technology includes a planar device for performing multiple biochemical assays at the same time, or nearly the same time. Each assay may include a biosample including a biochemical, enzyme, DNA, and/or any other biochemical or biological sample. Each assay may include one or more tags including dyes and/or other chemicals/reagents whose optical characteristics change based on chemical characteristics of the biological sample being tested. Each assay may be optically pumped to cause one or more of luminescence, phosphorescence, or fluorescence of the assay that may be detected by one or more optical detectors. For example, an assay may include two tags and a biosample. Each tag may be pumped by different wavelengths of light and may produce different wavelengths of light that is filtered and detected by one or more detectors. The pump wavelengths may be different from one another and different from the produced wavelengths.
