Abstract:
Systems and methods for providing multiple image fields or regions on a single, two-dimensional imaging sensor array of a data reader. A single sensor array may be divided into two or more imaging regions each of which may be used to render a separate view of an overall read volume. An image-side telecentric optical system may be utilized to divide the sensor array into the two or more imaging regions. A thin, high refractive index focal element (e.g., optical glass) may be positioned over at least one of the two or more imaging regions to provide multiple focus positions using a single telecentric optical system and a single sensor array. The multiple imaging regions may be used to capture images from different regions, and/or may be used produce a longer depth of field by combining overlapping depths of field of the multiple imaging regions.
