摘要： The laser diode of an optical scanning system is located in a separate unit and light therefrom carried to a remote scan head via an optical fiber. This reduces the size and weight of the scan head and reduces the temperature sensitivity of the scan head. The scan head may include an optical sensor for detecting light reflected from scanned symbols. Alternatively, the separate unit may house the sensor, and the same fiber or an additional fiber will collect the reflected light and transmit that light back to the sensor. The invention also encompasses a number of electromagnetic and piezoelectric systems for producing a scanning motion of the beam emitted by the scan head.

摘要： An integrated scanner for scanning a barcode is formed on a common substrate. The scanner may include a micro-machined mirror, a laser diode, and a detector, mounted on a single substrate or several connected substrates. Lenses can be used to focus a laser beam from the laser diode as well as expand a laser beam deflected by the micro-machined mirror. The scanner may also scan a barcode without using a micro-machined mirror by rotating the laser diode.

摘要： An integrated optical module for an optical scanner has a lens spaced from a vertical-cavity surface-emitting laser (VCSEL) by a spacer of defined dimensions. The module, in an alternative embodiment, includes a wafer frame, a suspended mirror mounted for oscillation on the frame, a wafer substrate bonded beneath the frame and a wafer cover bonded above the frame. The cover includes a mirror travel stop to protect the mirror against shocks. A VCSEL mounted to the wafer cover produces a beam which is shaped and deflected by a diffractive optical element onto the oscillating mirror. The reflected beam passes out of the module toward an indicia to be read. Large numbers of such devices may be fabricated relatively cheaply using wafer-scale processing and assembly technology. Three large wafers are fabricated corresponding respectively to arrays of substrates, frames and covers. The large wafers are bonded together in a sandwich arrangement, and are then diced to produce the individual scan modules. The modules may provide either one-dimensional or two-dimensional scanning.

摘要： A light scanning system formed on a common substrate comprises a light scanner and a sensor. The light scanner scans light across a target. The sensor detects light reflected from the target and creates a signal representative of the detected light. The light scanner may include a light source and a deflector, such as a micro-machined scan module. The micro-machined scan module may comprise an electrode, a support mounted on the electrode, and a mirror element mounted at one end of the support, wherein a voltage applied between the electrode and mirror element bends the mirror element.
