High-speed Hyperspectral Camera Captures Images In Under 200ms


Imec has developed its second generation high-speed SNAPSCAN hyperspectral imaging camera, SNAPSCAN, that combines the benefits of snapshot and linescan technologies. The camera uses an ultrasonic speed piezo motor stage and innovative software to enable the acquisition of high resolution hyperspectral images in less than 200ms. It thus minimizes the effects of motion artifacts during acquisition and can enable a wide range of new applications in the medical market such as digital pathology, wound healing, skin diagnostics and guided surgery.

The camera combines a high signal-to-noise ratio and high spatial and spectral resolutions with the user-friendliness of a snapshot hyperspectral imaging camera.

The SNAPSCAN camera handles all scanning internally using the miniaturized ultrasonic piezo scanning stage, thereby excluding the need for external scanning movement.

“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.”

“Today, spatial resolution of 3,650 x 2,048px (7MPx), with a spectral resolution of 150+ spectral bands can be reached over the VNIR spectral range (470 – 900nm) and the NIR range (600 – 975nm). Flat signal-to-noise ratios of 200:1 over the full spectral range are in reach, with optimized acquisition and lighting set-up parameters”, Imec claimed.

New Barometric Pressure Sensor For IoT Devices

“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 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,” explains 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.”
