Researchers from Friedrich Schiller University Jena, Ilmenau University of Technology and Fraunhofer Institute for Applied Optics and Precision Engineering, Germany, have developed a compact imaging system that can measure the three-dimensional shape as well as the spectral properties of objects with high speed and accuracy.
A new camera technology developed by scientists from Nanyang Technological University, Singapore (NTU Singapore) can take sharp, colour images without using a lens and colour filters. Using only a piece of ground glass and a monochrome sensor, the scientists created multi-coloured images by “reverse engineering” the light that is scattered by the translucent matt surface of the ground glass, thus obtaining the original image that was projected on to it.
Imec has developed its first shortwave infrared (SWIR) range hyperspectral imaging camera. It integrates CMOS-based spectral filters together with InGaAs-based imagers. For a number of years, semiconductor CMOS-based hyperspectral imaging filters, designed and manufactured by Imec, have been integrated monolithically onto silicon-based CMOS image sensors.
Imec has introduced its second generation, high-speed Snapscan hyperspectral imaging camera. This uses an ultrasonic speed piezo motor stage and innovative software to enable the acquisition of high-resolution, hyperspectral images in less than 200 ms. The Snapscan camera handles all scanning internally using the miniaturised ultrasonic piezo scanning stage, thereby avoiding the need for external scanning movement.
