“…For the Mars Express mission by ESA SPICAM (Spectroscopy for the Investigation of the Characteristics of the Atmosphere of Mars) was out of the model payload of the Mars Express project. Only an extremely lightweight near-IR spectrometer for the range of 0.9-1.7 µm based on AOTF technology was accepted by ESA as the IR channel of SPICAM [10][11][12]. The Mars Express orbiter has started science operations in January 2004.…”

“…AOTF is an electronically tunable optical filter, which works on the principle of Bragg's diffraction in a birefringent crystal (Korablev et al, 2002). The AOTF-NIRS uses acoustic waves to vibrate a sound-sensitive crystal inside the spectrometer.…”

Purpose:The aim of this study was to develop a technique for the non-destructive and rapid prediction of the moisture content in red pepper powder using near-infrared (NIR) spectroscopy and a partial least squares regression (PLSR) model. Methods: Three red pepper powder products were separated into three groups based on their particle sizes using a standard sieve. Each product was prepared, and the expected moisture content range was divided into six or seven levels from 3 to 21% wb with 3% wb intervals. The NIR reflectance spectra acquired in the wavelength range from 1,100 to 2,300 nm were used for the development of prediction models of the moisture content in red pepper powder. Results: The values of RV 2 , SEP, and RPD for the best PLSR model to predict the moisture content in red pepper powders of varying particle sizes below 1.4 mm were 0.990, ±0.487% wb, and 10.00, respectively. Conclusions: These results demonstrated that NIR spectroscopy and a PLSR model could be useful techniques for measuring rapidly and non-destructively the moisture content in red pepper powder.

“…The wavelength range covered is 1 to 1.7 μm, where the SPICAM was used for CO 2 and H 2 O detection. 6 Korablev et al 7 describe the use of the SPICAM measurement to study solar occultation, limb and nadir in the NIR and UV spectral ranges. An imaging instrument for ground-based astronomy was introduced in Ref.…”

Abstract. A prototype infrared (IR) acousto-optic tunable filter (AOTF)-based point spectrometer has been designed for examining and analyzing potential biological samples collected in situ from the planets or other solar system objects. The reflectance spectrometer operates at a wavelength range of 1.6 to 3.6 μm, which is diagnostic of minerals and organics, and inspects a 1-mm sized spot on the sample. The tuning component is the AOTF that has been utilized in a variety of spectral detection applications. The instrument's specification and design approach including the selected components is described. The data acquisition system, the electronic components, and their interconnections are presented. The instrument's radiometric performance is examined and described by a noise equivalent reflectance value of 0.13% that is obtained from the laboratory measurements. The device has been demonstrated by measuring the reflectance spectra for a variety of geological samples and comparing the results with the United States Geological Survey data. © The Authors.Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
