An integrated magnetic spectrometer for multiplexed biosensing

2013 IEEE International Solid-State Circuits Conference Digest of Technical Papers, 2013
There is high demand for at-home and point-of-care medical diagnostic tools as a step toward fast, low-cost, personal medicine. Integrated biosensors based on magnetic labeling schemes offer higher sensitivity and lower cost due to the elimination of the optics and have emerged as a viable alternative to assays that use fluorescence for biomolecular ...

Modeling of the spectrometer for INTEGRAL satellite

AIP Conference Proceedings, 2020
A probabilistic approach has been presented for modeling the spectrometer for INTEGRAL satellite (SPI). We have considered the isotropic scattering of gamma-rays inside the detector, as well as the equal absorption probabilities of successive gamma scatterings inside the detector.

Silicon-on-Insulator spectrometers with integrated GaInAsSb photodiode array for wideband operation from 1500 to 2300 nm. [PDF]

, 2013
Four echelle-type spectrometers with heterogeneously integrated GaInAsSb photodetectors on a silicon-on-insulator chip is realized. The operating wavelengths stretch from 1500 to 2300 nm.

AN INTEGRATED ULTRASONIC CORRELATION SPECTROMETER

AIP Conference Proceedings, 2008
A novel architecture for a low voltage ultrasonic data acquisition system is described. The system is appropriate for process monitoring in hazardous environments with potential fire or explosion hazards, where limits are imposed on the working voltage levels of equipment.

Miniature Integrated Spectrometer Array

2019 24th Microoptics Conference (MOC), 2019
We describe the design and set-up an array of micro-spectrometers for parallel sensing. The approach utilizes a prism – grating combination to obtain a linear light path and to achieve a high packing density. This yields 2’000 micro spectrometers of 6 mm length only when working with a 4/3” CCD image sensor.

The SPI Spectrometer for the Integral Mission

Physica Scripta, 1998
SPI (Spectrometer for INTEGRAL) is a high spectral resolution gamma-ray telescope to be flown on board the ESA mission INTEGRAL. It consists of an array of 19 closely packed Germanium detectors surrounded by an active anticoincidence shield of EGO. The imaging capabilities of the instrument are obtained with a tungsten coded aperture mask located 1.7 m

A time-delayed integration spectrometer

Measurement Science and Technology, 2002
A novel instrument is presented for measuring low-light near-infrared spectra of moving samples (such as objects on a conveyor belt). The spectrometer collects light from the sample as it travels along the conveyor, tracking it electronically using time-delayed integration.

An Integrated Optical Spectrometer for WDM

1997
Wavelength division multiplexed (WDM) systems have several channels of different wavelengths in the 1550 nm wavelength band. Implementation of WDM systems requires demultiplexers to separate the different wavelengths. Compact, low loss demultiplexers can be realized using integrated optical spectrometers.
