Chip-scale spectral sensing: understanding the new uses for ultra-precise light-source measurement

How manufacturers can use the spectral information which image or color sensor cannot see to create better performing, safer or enjoyable products.

The accurate rendition of color in camera, imaging and lighting systems is highly valued by consumers and professional buyers. Developments in color sensing have recently seen the introduction of a new generation of multi-channel spectral sensors which for the first time provide for chip-scale spectral analysis of incident light – a more detailed type of information than color or image sensors provide.

This white paper describes how a spectral sensor IC provides accurate color measurements backed by reliable detection of the signature of any kind of visible light source. It then explains its use cases in high-performance cameras and imaging equipment, in tunable and human-centric lighting systems, and for sophisticated environment awareness in wearable devices.
