    摘要: A decodable indicia reading terminal can comprise a laser-based scanner, an imager-based scanner, a central processing unit (CPU), and an illumination assembly. The laser-based scanner can include a laser source, a photo-detector, and an analog-to-digital (A/D) converter. The laser source can be configured to emit a laser beam onto a substrate bearing decodable indicia. The photo-detector can be configured to receive a beam of a variable intensity reflected by the decodable indicia, and to output a first analog signal representative of the variable intensity. The A/D converter can be configured to convert the first analog signal into a first digital signal. The imager-based scanner can include a multiple pixel image sensor, an imaging lens, and an A/D converter. The imaging lens can be configured to focus an image of the decodable indicia on the image sensor. The A/D converter can be configured to convert into a second digital signal a second analog signal read out of the image sensor and representative of light incident on the image sensor. The CPU can be configured to output a decoded message data corresponding to the decodable indicia by processing the first digital signal and/or the second digital signal. The illumination assembly can include an indicator light bar and an illumination light bar. The ON/OFF state and color of the indicator light bar can reflect the state of the decodable indicia reading terminal. The illumination light bar can be configured to generate a high intensity illumination for illuminating the substrate bearing the decodable indicia. The wavelength of the light generated by the indicator light bar can be substantially equal to the wavelength of the light generated by the illumination light bar, and the light generated by the illumination light bar can have a very low perceived intensity.

    摘要: Embodiments of an indicia reading terminal have multiple fields of view (“FOV”). This feature allows decoding of decodable indicia that exhibit different characteristics. These characteristics may affect the ability of the terminal to identify and decode the information stored therein. In one embodiment, the terminal comprises an optical imaging assembly with at least two FOVs. One of the FOVs is adequate to acquire information from decodable indicia with higher density than other decodable indicia.
