Latest Patents

Hochgraf holds a patent for an "Optical system for a large depth-of-field bar code scanner." This invention features an optical system where the working range is determined by the dimension and orientation of the detector rather than the lens aperture. The preferred embodiment utilizes a modified Scheimpflug arrangement to image the desired working range onto a detector array. This design allows for a large lens aperture, maximizing resolution and minimizing illumination needs without compromising the working range. The illumination for the bar code scanner is directed along the second Scheimpflug plane, which is off the optical axis of the lens, eliminating the need for conventional beam splitters or mirror/aperture arrangements.
