    Abstract: 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.

    Abstract: A portable scanning head emits and receives light from a light-emitting diode (10) to read symbols, such as bar-code symbols. The optics (12,18) within the scanner are operative for focusing a light beam (11) and the view of a light sensor (17) in different planes (13,22) exteriorly of a scanner housing. Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED (10) as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode (17) "sees" only that portion of the scan spot visible through the viewing window.
