A report on the 12th Confocal Raman Imaging Symposium held in Ulm, Germany, September 2015, which covered a fascinating range of applications of the technique.
Andor Technology has announced the launch of the new, enhanced iKon-M 912 back-illuminated CCD camera.
Specim have introduced the new range of AisaKESTREL pushbroom hyperspectral sensor systems.
Oriel Instruments has introduced the MS260i series of ¼-m imaging spectrographs.
Princeton Instruments has added the ProEM-HS:1024BX3 to its line of high-speed EMCCD cameras.
Inno-Spec are introducing the OrangeEye Lab, a laboratory spectral imaging camera for the visible and very near infrared regions.
A microscope being developed at the US Department of Energy’s Oak Ridge National Laboratory will allow scientists studying biological and synthetic materials to simultaneously observe chemical and physical properties on and beneath the surface.
Many details of the wall and ceiling frescos in the cloister of Brandenburg Cathedral have faded: Plaster on which horses once “galloped” appears more or less bare. Hyperspectral imaging reveals images that remain hidden to the human eye, however, and is thus a big help for art historians.
BaySpec’s OCI-UAV is an ultra-compact version of its OCI-Series Hyperspectral Imagers. The camera is designed specifically for use on unmanned aerial vehicles/systems (UAV/UAS) and similar platforms.
The ProEM-HS line of high-speed EMCCD cameras from Princeton Instruments make use of patented eXcelon 3 technology for low-light imaging and spectroscopy applications.
Headwall has introduced a new hyperspectral imager for very high resolution measurements of 0.1 nm over specific spectral ranges.
iBruker has released Inspire, an integrated scanning probe microscope infrared system for 10-nm spatial resolution in chemical and materials mapping.
Perception Studio is a software suite for hyperspectral data acquisition and processing, based on an extensible plug-in framework, allowing generic access to hyperspectral data.
Elucidating structural and compositional changes in plant tissues and single cells by Raman spectroscopic imaging
“Elucidating structural and compositional changes in plant tissues and single cells by Raman spectroscopic imaging” is the topic of the next article by Batirtze Prats Mateu, Barbara Stefke, Marie-Theres Hauser and Notburga Gierlinger. Understanding plant cells is important for the best use of plants in traditional and new applications. Raman spectroscopic imaging represents one of the best ways to unravel the molecular structure in the native environment of plant tissues.
Multisensor hyperspectral imaging as a versatile tool for image-based chemical structure determination
Hans Lohninger and Johannes Ofner describe “Multisensor hyperspectral imaging as a versatile tool for image-based chemical structure determination”. They describe the features of a software package that allows the combined analysis of hyperspectral data from different imaging techniques. This multisensor approach providing complementary information has many advantages.
Curtis Marcott, Tadashi Awatani, Jiping Ye, David Gerrard, Michael Lo and Kevin Kjoller give us a “Review of nanoscale infrared spectroscopy applications to energy related materials”. Fuel cells, photovoltaics and specialised polymers for fracking are all considered.
This article describes an application of spectral imaging for the differentiation of tumour and normal cells. The authors also introduce the concept of a spectral barcode, which has had success with some tissues and has potential in others.
Near infrared hyperspectral imaging for foreign body detection and identification in food processing
With continuing food scares around the world, food producers need every tool they can get to prevent contamination of their products at every stage of production. Hyperspectral reflectance imaging in the NIR combined with chemometrics shows much promise for the detection and identification of foreign bodies among food grains.
There are a number of approaches, and by combining FT-IR imaging methodology with microfluidics devices, the opportunity to study live cells by FT-IR imaging in controlled environments is now possible.
