Magalie BONDU and Michael MARIA Copenhagen, French Ambassy (DK) 25th of May 2016 We went visiting the new Metro construction in Copenhagen and get introduced to the project. We met Sandra Akmansoys CEO of ARUP Denmark which is in charge of the project. We had interesting talks with other french engineers based in Denmark.
In this project the possibility of using a supercontinuum in the visible wavelength range for spectroscopic analysis in combination with imaging, so called spectroscopic optical coherence tomography is investigated. Spectroscopic optical coherence tomography combines imaging of optical coherence tomography with localized absorption, which is used as functional information. These functional information are asked for from Read more about Spectroscopic visible light optical coherence tomography[…]
The supercontinuum source we are working with are commercial products from NKT Photonics and have the great feature of covering a large spectral bandwidth. These sources cover from the visible light up to the infrared wavelengths, to be precise from around 450 nm to 2400 nm. Because of this broad bandwidth we can use different Read more about Ultra-wide optical coherence tomography in different wavelengths regions using a supercontinuum source[…]
When light is focussed by a lens or a spherical mirror we assume that we can focus down the light into a very small spot, unfortunately can we not achieve such a small spot, because of imperfection of the lens surface and curvature. By detecting the wavefront of light we can see how much imperfection Read more about Different wavelength scanning laser ophthalmoscope (SLO) combined with adaptive optics for spectral analysis of sample[…]
by Catherine Chin for project “Comprehensive theory of noise in SC optical sources and out of interferometers driven by SC optical sources” Part 1: Noise in supercontinuum sources Noise from optical sources is one particular concern when designing an OCT imaging system. The commercial needs for resolution and sensitivity often come as a compromise to image quality. Read more about Noise in OCT[…]
