Imaging barcode scanner with multiple independent fields of view

摘要

A barcode scanner which uses different wavelengths of light to produce different fields of view. An example barcode scanner includes a plurality of light devices each having a different wavelength of light and each associated with a different field of view for illuminating an item with a barcode, a plurality of waveband mirrors each reflecting one of the different wavelengths of light from the light devices and transmitting other wavelengths of light, an imager for receiving the different wavelengths of light reflected from the waveband mirrors and for producing corresponding images, and a controller configured to sequentially activate the light devices and the imager and to decode the barcode in an at least one of the images received from the imager.

主权项

1. An image capture device comprising:
a plurality of waveband mirrors each reflecting a different wavelength of light associated with a different unique field of view and each transmitting wavelengths of light other than the different wavelength of light; and an imager for receiving the different wavelengths of light reflected from the waveband mirrors, wherein the imager receives each wavelength for each field of view individually at a particular instant in time from a particular light device that is pulsing at a given frame rate recognized by the imager.
