Abstract
Abstract A hand-held produce data collector which captures wavelength information from a produce item. The produce data collector includes a light emitter for illuminating a produce item, collecting optics for collecting light reflected from the produce item and separating the reflected light into a plurality of wavelength portions of light, a photosensor for capturing wavelength information from the wavelength portions of light, control circuitry, and a hand-held housing containing the light emitter, the collecting optics, the photosensor, and the control circuitry. The control circuitry may store reference wavelength information and compare the captured wavelength information to the reference wavelength information to identify the produce item.
