Hyperspectral Imaging Concept. Hyperspectral imaging is a powerful new technology based on spectroscopy. It is based on collecting hundreds of images at different wavelengths from the same spatial area. The collected data form a hyperspectral cube, in which two dimensions represent the spatial coordinates (x,y), while the third coordinate shows wavelength (L). Hyperspectral imaging yields the spectrum for each pixel in the image, making it possible to find objects, identify materials, or detect hidden text or images otherwise invisible to a naked eye using a variety of mathematical algorithms. Additional information about the basics of hyperspectral imaging can be found on wikipedia page or by watching this youtube video.
Nuance EX Hyperspectral Imaging system availble at OIPH Nuance EX Hyperspectral Imaging system from PerkinElmer is capable of capturing wavelengths between 460-920 nm at a spatial resolution of 1392x1040 pixels. Nuance custom software can then perform spectral unmixing based on regions-of-interest, real component analysis or spectral libraries derived previously. The camera unit can be mounted on a microscope to analyze the smallest objects or minute details of the manuscript. It can also be equipped with long distance objective for acquiring data from larger objects such as inscriptions on the buildings. For more info about Nuance EX download its PDF manual.
