Optical and electronic crosstalk in the Focal Plane Assemblies (FPAs) of satellite instruments degrades the radiometric quality of remote sensing data, and can be a major limitation to achieve performance quality needed for environmental and climate monitoring research. Correction algorithms for this effect have been developed, such as the one developed for MODIS short wave infrared (SWIR) band...

We describe the development of a novel multispectral microscope, based on light-emitting diodes, capable of acquiring megapixel images in thirteen spectral bands from the ultraviolet to the near infrared. The system captures images and spectra in transmittance, reflectance, and scattering modes. We present as examples of applications ground truth measurements for remote sensing and parasitology...

A “breadboard” model of the proposed satellite infrared spectrometer for the measurement of atmospheric temperature profiles was used in two experiments a t ground level. These were designed to demonstrate the feasibility of the instrument and to investigate some of the hazards involved in inverting the radiation integral. I t is shown in the second experiment that realistic temperature profile...

The Airborne Visible / Infrared imaging Spectrometer AVIS is a hyperspectral imager designed for environmental monitoring purposes. The sensor, which was constructed entirely from commercially available components, has been successfully deployed during several experiments between 1999 and 2007. We describe the instrument design and present the results of laboratory characterization and calibrat...

In this article, recent measurements made with LIFTIRS, the Livermore Imaging Fourier Transform InfraRed Spectrometer, are presented. The experience gained with this instrument has produced a variety of insights into the tradeoffs between signal to noise ratio (SNR), spectral resolution and temporal resolution for time multiplexed Fourier transform imaging spectrometers. This experience has als...

We have developed an on-the-fly scanning spectrometer operating in the UV-visible and near-infrared that can simultaneously perform transmission and total reflectance measurements at the rate better than 1 sample per second. High throughput optical characterization is important for screening functional materials for a variety of new applications. We demonstrate the utility of the instrument for...

We report the design and testing of an instrument implementing thermal multiplexing for rapid microfluidic amplification of multiple DNA targets with different optimal annealing temperatures. Through spatial modulation of an infrared laser, distinct temperature profiles can be generated simultaneously in an array of microfluidic reaction chambers in a polymer device. For our dual-chamber system...

We have observed 49 X-ray detected bright late B-type dwarfs to search for close low-mass pre-main sequence (PMS) companions using the European Southern Observatory’s ADONIS (Adaptive Optics Near Infrared System) instrument. We announce the discovery of 21 new companions in 9 binaries, 5 triple, 4 quadruple system and 1 system consisting of five stars. The detected new companions have K magnitu...
