Abstract
A device, arrangement, and scanner are provided which are compact, reliable, and cost effective. The device is generally of the type in which a moving beam is scanned along a target object, and light reflected from the target object is detected and analyzed by the device. The device is preferably mirrorless. In addition, the device preferably lacks an integrated scanning component which imparts motion to the beam. In this regard, the device is provided with means for interacting with a separate adjacent scanning component, as well as a flexible connection means.
Claims46
A device comprising:
- means for providing an oscillating magnetic field;
- a printed circuit board;
- a moving beam scanner, the scanner comprising:
- a substrate;
- a laser light source mounted to the substrate;
- at least one light receiving photodiode mounted to the substrate;
- a cap mounted over the substrate;
- a lens for focusing the laser light source onto a target;
- a lens for collecting light reflected from the target;
- means mounted to the scanner for interacting with the means for providing an oscillating magnetic field;
- at least one flexible connector mechanically and electrically coupling the scanner and the circuit board such that a range of oscillation between the scanner and the circuit board is possible;
- and
- wherein the scanner lacks a mirror and a scanning component.
In combination, a moving-beam scanner and a scanning component for imparting motion to the beam:
- the scanner comprising:
- a substrate;
- a light source mounted to the substrate;
- at least one light-receiving photodiode mounted to the substrate;
- a cap mounted over the substrate;
- a lens for focusing the light source onto a target;
- a lens for collecting light reflected from the target;
- means mounted to the scanner for interacting with the scanning component;
- and
- wherein the scanning component is positioned adjacent to and outside the cap.
A moving-beam scanner comprising:
- a light source;
- at least one light-receiving photodiode;
- lens means for focusing the light source onto a target and collecting light reflected from the target;
- housing means;
- and
- means associated with the scanner for interacting with a scanning component to impart motion to the beam while maintaining the light source, lens means, and housing means fixed relative to each other;
- wherein the housing means lacks a mirror.
