Cea-Leti’s spectral imaging tech spots 94% of cancer cells

Scientists have developed a lensless, infrared spectral-imaging system for medical diagnostics

C Tech Focus sponsored by

ea-Leti scientists have developed a lensless, infrared spectral

imaging system for medical diagnostics. The French research agency has a startup in incubation based on the early-stage technology. The technology has been demonstrated in cancer detection in tissue samples, and also in identifying and discriminating between species of bacteria. The group says the label-free technology could eliminate sample preparation and therefore lead to greater

automation in diagnostics. The work was presented during SPIE Photonics West, which took place in March in a digital format.

The scientists showed

that the mid-wave infrared multispectral imaging method could detect cancer more accurately and faster than a human assessing a tissue sample, which is the standard practice for identifying cancer. The paper reported that by

analysing images from mice tissue using amide and DNA absorption bands, the team ‘achieved up to 94 per cent of successful predictions of cancer cells with a population of 325 pixels corresponding to muscle tissues, and 325 pixels corresponding to cancer tissues. This work may lead to the development of an imaging device that could be used for cancer diagnosis at hospitals.’


Hera Iperspettrale A novel Fourier- Transform based hyperspectral camera for low light applications


Nireos is an award-winning spin-off company from Politecnico di Milano University, based in Milan (Italy). Nireos develops and provides innovative spectroscopic solutions for industrial and scientific applications. Hera Iperspettrale is the

novel hyperspectral camera based on a patented Fourier- transform approach. Thanks to this technique and to its 1-cm clear aperture, the camera features an exceptional sensitivity. It can be thus used to measure extremely weak signals, enabling

fluorescence hyperspectral imaging. Also, Hera Iperspettrale provides high spatial and spectral resolution and operates in a staring approach (it can be easily mounted on a tripod), allowing for high-quality measurements, both in reflectance and fluorescence conditions. The device can be

employed in a large variety of applications, ranging from cultural heritage to biology, from material sorting and food inspection to remote sensing and vegetation studies.

The camera is available in

the VIS-NIR (400-1000nm), SWIR (900-1700nm) and Extended SWIR (900- 2300nm) versions. Find out more at:
