An automated integration routine for FT-IR spectrometers

Computers & Chemistry, 1989
Abstract An integration routine, written in Pascal, is shown that can automatically choose end points for infrared spectral peak integration. The routine accepts data generated from JCAMP-DX software. This paper includes a listing of the program and shows some of its limitations.

The spectrometer SPI of the INTEGRAL mission

AIP Conference Proceedings, 2000
The spectrometer on INTEGRAL (SPI) is one of the two main telescopes of the future INTEGRAL observatory. SPI is made of a compact hexagonal matrix of 19 high-purity germanium detectors shielded by a massive anticoincidence system. A HURA type coded aperture modulates the astrophysical signal.

Development of a thermoluminescence and radioluminescence integrated spectrometer

Measurement, 2019
Abstract The knowledge of the thermoluminescence and radioluminescence spectra is important for understanding the nature of luminescence emitted by thermoluminescent dosimeters and scintillators. In view of that, an instrument that records these two types of spectra was developed.

[The integrative design for imaging spectrometer].

Guang pu xue yu guang pu fen xi = Guang pu, 2015
The hyperspectrum imaging spectrometer will achieve miniaturization and high spectrum resolution and high space resolution along with development of the hyperspectrum imaging technology that is becoming a trend. This trend requires the designers to improve and optimize their designing constantly in designing the instruments.

Design and Implementation of an Integrated Magnetic Spectrometer for Multiplexed Biosensing

IEEE Transactions on Biomedical Circuits and Systems, 2013
Magnetic spectroscopy allows for characterization of the magnetic susceptibility of magnetic beads across a broad frequency range. This enables differentiation and quantification of multiple beads of varying types concurrently present in the active volume of a sensor's surface.

Miniaturization and module integration of an infrared spectrometer

Optical Engineering, 2001
When designing a miniaturized optoelectronic module, modeling of the system allows us to optimize structures, materials, and components to achieve optimal performance and cost effectiveness of the final product. We have used an approach in which an analytical model and simulation model support each other to speed up and enhance the system's development

Characterization of integrating sphere homogeneity with an uncalibrated imaging spectrometer

2013 5th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2013
The radiometric calibration of imaging spectrometers is usually performed using integrating spheres as light sources. Their homogeneities are usually defined for the entrance aperture. As airborne hyperspectral sensors are focused on infinity, the calibration of such sensors is done in a way which is not well defined.

Miniaturized spectrometers using integrated optics

SPIE Proceedings, 2017
In this work, two different integrated-optics based spectrometer designs are presented. The first one is called interleaved arrayed waveguide grating (AWG) spectrometer provides large bandwidth (i.e. 30 nm) and high resolution (i.e. 0.1 nm) for a compact size (i.e. 2.4 cm × 3 cm).

Towards an Integrated Optofluidic Diffractive Spectrometer

IEEE Photonics Technology Letters, 2007
We demonstrate an optofluidic lab-on-a-chip device by fabricating an optical transmission grating with an integrated microfluidic channel using soft lithography in polydimethylsiloxane. This integration of functionalities provides spectral analysis ldquoon-chiprdquo of the contents of the microfluidic channel.
