A Real-Time 3D Range Image Sensor based on a novel Tip-Tilt-Piston Micro-mirror and Dual Frequency Phase Shifting

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1255450

Structured light is a robust and accurate method for 3D range imaging in which one or more light patterns are projected onto the scene and observed with an off-axis camera. Commercial sensors typically utilize DMD- or LCD-based LED projectors, which produce good results but have a number of drawback...

Low-cost resonant cavity Raman gas probe for multi-gas detection

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1187502

Raman based gas sensing can be attractive in several industrial applications, due to its multi-gas sensing capabilities and its ability to detect O2 and N2. In this article, we have built a Raman gas probe, based on low-cost components, which has shown an estimated detection limit of 0.5 % for 30 se...

Low cost laserless FTIR spectrometer on the farm for real-time nitrous oxide soil emission measurements

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1002744

A low-cost Fourier transform infrared (FTIR) instrument was developed where the traditional He–Ne reference laser was replaced by a low-cost linear encoder. An RMS sampling error of less than 20 nm was achieved by oversampling both the interferogram and the encoder signal and then resampling the int...

Low Cost “Laserless” FTIR Spectrometer with Resolution Better Than 0.5 cm-1

https://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S21566

Abstract: We have designed a FTIR instrument where the traditional He-Ne reference laser is replaced by a low-cost linear encoder. We achieve an RMS sampling error of less than 50nm by oversampling both the interferogram and the encoder signal and then resampling the interferogram using a correction...

An interferometric test station for massive parallel inspection of passive and active M(O)EMS

https://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S12980

The paper presents the optical, mechanical, and electro-optical design of an interferometric inspection system for massive parallel inspection of M(O)EMS. The basic idea is to adapt an micro-optical probing wafer containing interferometer arrays to the M(O)EMS wafer under test....

Design of a micro-optical low coherent interferometer array for the characterisation of MEMS and MOEMS

https://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S12974

The EU-project SMARTIEHS (SMART InspEction system for High Speed and multi-functional testing of MEMS and MOEMS) develops a new inspection concept for MEMS and MOEMS (M(O)EMS) testing on the wafer level. The inspection systems on market today are based on a serial approach inspecting one M(O)EMS str...
