Abstract:
A method and apparatus are provided for simulating a bar code. The bar code simulator includes a code emitter for generating a coded light beam which varies sequentially in intensity to correspond with bar code bars and spaces, and varies sequentially in duration to correspond with varying width of the bars and spaces. The flashing light beam so produced corresponds with the flashing back scattered light which would otherwise be produced by sweeping a scan beam across a bar code label. The independently produced coded beam simulates back scattered light which is identically detected by a scanner and decoded thereby.
