Multi-Zone Diffractive Mask for Fine Control of Light Amplitude and Phase
This invention is a mask that can be used in an optical setup to diffract an amount of light based on wavelength. The mask is placed within the focal plane to solve the size-chromaticity problem by using this phase technique. This will achieve better resolution and high start to planet contrast.
Background:
In the study of the Sun's corona, light...

A Fast Compression Algorithm For Images And Video Capable Of Real-Time Speed
This technology is an algorithm that provides real-time, high performance, “lossless” data compression.
Background:
Data compression algorithms, such as a zip file, reduce the number of bits needed to store or transmit digital information. The performance of the algorithms is often quantified in terms of a compression ratio. For example,...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
