We have developed a spectral image sensor based on CMOS image sensor for smartphone. The spectral image sensor consists of optical bandpass filter array integrated on top of image sensor pixels. Each filter has a different transmission wavelength peaks so spectral information is directly retrieved by intensity map of the image sensor. We applied the spectral sensor technology to 1) Raman spectroscopy for drug identification, 2) Freshness detection of vegetables and 3) hyperspectral imaging applications for color enhancement, food inspection and skincare.
