摘要:
A system for scanning objects having at least two linear array sensors, adapted to detect light input signals, is provided. A lens is optically connected to each of the linear array sensors, and are adapted to receive and transmit an optical image located in a respective lens field of view along a respective lens axis to the respective one of the at least two linear array sensor. A light source which generates an illumination stripe in general linear alignment with the lens axis across a depth of the field of view is provided. A cylindrical lens is positioned between the light source and an object to be scanned. The cylindrical lens adapted to collect, transmit and focus light from the light source to form the illumination stripe. This arrangement provides a wider system field of view with generally more uniform resolution.

A system for scanning objects having a linear array sensor, adapted to detect light input signals, is provided. A lens is optically connected to the linear array sensor, and is adapted to receive and transmit an optical image located in a field of view along a lens axis to the linear array sensor. A light source is used to generate an illumination stripe. A cylindrical lens is positioned between the light source and an object to be scanned. The cylindrical lens is adapted to collect, transmit and focus light from the light source to form the illumination stripe. The linear array sensor, lens axis, and illumination stripe are co-planar and parallel.
摘要:
A focus changing apparatus for an optical scanner which increases the depth of the field of the optical scanner. The focus changing apparatus is optically located between a laser source and a scan mirror and includes a plurality of alternating curved and flat facets. Alternatively, a piezoelectric deformable mirror may be optically located between the laser source and a flat faceted scan mirror to provide for increased depth of field of the optical scanner.

摘要:
A modular camera having a chassis module, a camera module, an illumination module and a communications module that together form a cooling passageway. The chassis module has a back wall having a first end and an opposite second end, a bottom wall having at least one opening formed therein, a first fan mounted at the chassis back wall first end, and a second fan mounted at the chassis back wall second end. The camera module has a body, wherein the camera body is removably received through a hole formed through the chassis module back wall. The illumination module has a back wall, wherein the illumination module is removably coupled to the chassis module so that the illumination module back wall is spaced apart from the chassis module back wall. The communication module is removably coupled to the chassis module. The chassis module back wall, the camera module body, the illumination module back wall and the communications module together form a cooling channel.
