In this paper, we demonstrate an improvement in the accuracy of a low-cost smart temperature sensor, by measurement of the nonlinear curvature correction at multiple temperature references. The sensors were positioned inside a climate chamber and con

Target and Background Signatures IV.
To validate thermal infrared signature models, we need data from well-characterized targets, typically of simple geometric shape measured under known atmospheric and environmental conditions. An important parameter of the target's signature is the va

Compared with the other Infrared detector materials, such as HgCdTe (or MCT) and lead salts (e.g.: PbS, PbSe, PbSnTe, …), the history of InGaAs FPA’s is not that old. Some 25 years ago the first linear detectors were used for space missions [1,2]

This paper presents a novel integrated Micro-Opto-Mechanical Pressure Sensor that exhibits an excellent measurement precision in a large pressure range. The performance gain compared to classical designs is obtained by using a phase shift and by comb

Optical coherence tomography (OCT), a spectroscopy technique, has been used in biomedical applications for about 20 years. It has evolved to a standard non-invasive examination procedure yielding detail-rich cross-sectional images of living tissue. W

Xenics has developed a family of stitched SWIR long linear arrays that operate up to 400 KHz of line rate. These arrays serve medical and industrial applications that require high line rates as well as space applications that require long linear arra

In this paper, we describe the temperature and thermal variations from a painted geometrical target (CUBI) fitted with a network of internally mounted 1-wire temperature sensors. The sensors, which were calibrated in a temperature-controlled oven, we

We determine the radial profile of the photoelastic constant C(r) in two single mode and one multimode polymer optical fibers (POFs), all fabricated from polymethylmethacrylate (PMMA). To determine C(r) we first determine the retardance of the latera

We compare two algorithms to determine the radial profile of the photoelastic coefficient C in glass optical fibers. We first measure the retardance profile of a transversally illuminated fiber as a function of tensile load. The radial profile C(r) i

This paper presents a fully integrated lock-in amplifier intended for nanowire gas sensing. The nanowire will change its conductivity according to the concentration of an absorbing gas. To ensure an accurate nanowire impedance measurement, a lock-in
