At SPIE Photonics West, Imec presented a prototype hyperspectral imager for snapshot and video acquisition.

Imec's CMOS-based imaging systems with integrated hyperspectral filters are suited for multiple industrial vision applications. The company is currently sampling the line scan version of its hyperspectral imaging solution, offering a ready-to-use evaluation kit to the industry to line scan and analyse specific sample material.

Imec’s prototype hyperspectral imager for snapshot and video captures an entire multispectral image at one discrete point in time. The imager is achieved by applying a hyperspectral filter in a novel tiled lay-out on a commercially available CMOS-based image sensor (Cmosis CMV2000, 2 megapixel, max 340fps).

The imager and off-the-shelf fore-optics simultaneously duplicates the scene onto each filter tile, acquiring multispectral image cubes of 256 x 256 pixels over 32 bands in the spectral range of 600-1000nm at up to 340 cubes per second - compliant to normal machine vision illumination levels.

Due to its simple cube assembly process, the camera is able to acquire real-time hyperspectral video.
