OBJECT IDENTIFICATION SYSTEM

摘要

An object identifying system is described comprising at least a device for remotely identifying objects and a plurality of objects bearing each a coded information in the form of a badge which has alternating reflective and non-reflective stripes. The objects are moving past the device, but can also be motionless. When illuminated by a light source, the badge reflects a part of the incident light beam to an opto-electrical transducer means which is formed by a number of diodes in a row. Control means allow the photodiodes to be switched in succession and in this way the photodiodes analyse the badge. The length of the row of diodes is generally greater than the length of the code support to allow for any possible misalignment between the support and the identification device.
