imec’s SNAPSCAN camera enables hyperspectral imaging acquisition in 200 ms

Jan. 29, 2018

San Francisco, CA. imec today announced that it will demonstrate at this week’s SPIE Photonics West in San Francisco its second-generation high-speed SNAPSCAN hyperspectral imaging camera. The new hyperspectral camera uses an ultrasonic-speed piezo motor stage and innovative software to enable the acquisition of high- resolution hyperspectral images less than 200 ms. imec said the technology will enable its partners to develop consistent spectral libraries and customized solutions faster than ever possible before for a wide range of new applications in the medical market.

The SNAPSCAN hyperspectral camera is a proprietary breakthrough system concept initially introduced by imec one year ago. It combines a high signal-to-noise ratio and high spatial and spectral resolutions with the user friendliness of a snapshot hyperspectral imaging camera.

“We have been thrilled by the commercial success of the first generation SNAPSCAN camera, which was introduced at SPIE Photonics West 2017,” explained Andy Lambrechts, program manager for integrated imaging activities at imec. “By introducing an ultrasonic speed piezo motor stage, we can now guarantee image acquisition times of less than a second, and thus minimize the effects of motion artifacts during acquisition. As a result, we can now enable many more key applications such as digital pathology, wound healing, skin diagnostics, and guided surgery.”

imec’s new SNAPSCAN camera handles all scanning internally using the miniaturized ultrasonic piezo scanning stage, thereby excluding the need for external scanning movement. Today, spatial resolution of 3,650 x 2,048 pixels (7 Mpixels), with a spectral resolution of 150+ spectral bands, can be reached over the VNIR spectral range (470 to 900 nm) and the NIR range (600 to 975 nm). With imec’s proprietary hyperspectral imaging acquisition software, specific spectral regions of interest can now be selected, which enables acquiring images at a very high speed of only 200 ms. Flat signal-to-noise ratios of 200:1 over the full spectral range are in reach, with optimized acquisition and lighting set-up parameters.

“We believe our new high-speed ultrasonic SNAPSCAN camera technology will further open the market for all users who intend to bridge the gap between academic research and commercial development. The second generation ultrasonic high-speed SNAPSCAN camera’s ability to easily create high-quality datasets will enable our partners to move from initial application validation to building consistent spectral libraries and application solutions faster than ever possible before,” explained Jerome Baron, business development manager at imec’s integrated imaging and vision system teams. “With a full year of commercialization under our belts, we have validated many clear commercial opportunities beyond the R&D market such as the medical market.”

Imec’s ultrasonic SNAPSCAN hyperspectral imaging cameras are being demonstrated for the first time at SPIE Photonic West in San-Francisco and will be commercially available in April 2018.
