MEMs based bar code scanning

Intermec Technologies has introduced a new bar code laser scanning technology that it claims is more compact and reliable and offers longer product life than current bar code laser scan engines.

The new EXCELerate bar code laser scan engine, based on a technology known as Micro Electro Mechanical System or MEMS, is the result of five years of development collaboration with the Fraunhofer Institute for Photonic Microsystems (IPMS) in Dresden, Germany.

The company says that MEMS technology produces a laser scan engine with entirely new capabilities, including faster scan rates and improved durability. Initial scan rates are five times faster than current mechanical motor-based laser scanners.

This speed will allow precise high-speed scanning in two dimensions and will provide omni-directional reading of 1D and stacked bar-codes, as well as 2D raster scanning for matrix codes.

The MEMS-based laser scan engines expand Intermec’s broad selection of bar code scanning and 1D and 2D imaging capabilities. The first in the MEMS family of Intermec laser scan engines, the EXCELerate EL10, will be offered as the integrated laser scanner in a number of Intermec handheld computer and scanner products that will be available in Latin America, Southeast Asia, portions of Europe, the Middle East and Africa in the first half of 2005. Worldwide availability is scheduled for the second half of 2005.

The EXCELerate EL10 can be programmed to read a variety of bar code symbologies, including 1D, and PDF 417. Future versions of the family will be able to precisely scan in multiple directions to read 2D bar-codes.
