Encapsulating insulin producing cells (INPCs) in an immunoisolation device have been shown to cure diabetes in rodents without the need for immunosuppression. However, micro-encapsulation in semi-solid gels raises longevity and safety concerns for fu

The potential benefit of combined spectral and spatial imagery in the classification/monitoring study of events and processes has created strong interest in the class of remote sensors identified as imaging spectrometers. The production and commercia

We report performance measurements of a photodiode array Hadamard transform spectrometer (HTS) with a stationary entrance mask. The high throughput of the multi-slit, no- moving parts instrument is shown to yield a significantly higher S/N ratio than

An electroless nickel plated over aluminum mirror was tested for BRDF and surface profiles at two stages: First, after a standard polish for optical figure, and second, after a `super finishing process' which is designed to minimize optical scatter.

A 6-inch diameter aperture space-based visible telescope has been optimized to perform surveillance against the space background with earth albedo as a primary source of straylight. A three mirror off-axis anastigmat has been designed to cover a 1.4

The contamination control of telescopes with the straylight-rejection capability is reviewed to identify the degradative effects of contaminant phenomena on the measurements. Three levels of optical contamination are discussed including bidirectional

Hadamard spectrometers are well known for their multiplexing and/or throughput advantages. Traditionally these instruments require moving entrance and/or exit masks. The performance of a breadboard photodiode-array Hadamard transform spectrometer wit

Recent re-measurement of the Out-of Filed-of View-Rejection (OFVR) characteristics of the ZIP telescope #2 indicated that the Point Source Power Transmittance (PSPT) was increased by as much as a factor of 400 at one off-axis source orientation in co

A Hadamard transform spectrometer has been designed which uses a stationary Hadamard mask at the entrance plane of a holographic grating, photodiode array spectrometer. The mask contains 2N-1 slots where N is the number of resolution elements in the
