Multispectral Imaging Systems from Surface Optics Corp & PIXELTEQ

Real-time multispectral imagers are based on 2D image sensors overlaid with an array of discrete, bandpass filters. There are two types of multispectral imager: those employing "filter-on-chip" technology, in which a series of narrow bandpass filters are applied directly to the 2D sensor array; and those employing an interchangeable filter array together with plenoptic imaging. A multispectral imager provides a more limited spectral dataset but provides a distinct advantage in terms of measurement speed. A multispectral camera can generally be regarded as a "real time" spectral imager, allowing for the capture of rapidly changing objects.

Multispectral Filter-on-Chip Imagers   Surface Optics Corp LigthPath Multispectral Imager    

The PixelCam™ OEM multispectral camera from PIXELTEQ provides "live" video rate spectral imaging with between 3 and 9 spectral bands. Custom dichroic filters are applied onto the 2D sensor array at the wafer level to create a robust camera that can be used for spectral monitoring at descrete visible and NIR wavelengths.
