Designed to speed industrial inspection systems--such as detecting whether food is spoiled--the new smart camera includes spectral filters that make images of corn fields appear differently from hemp. Spectral cameras have been available for decades, but this microchip version should be cheap enough for almost any application--including law enforcement.
