Abstract
An electrically programmable reticle is made using at least one electrochromatic layer that changes its optical transmissibility in response to applied voltages. Transparent conductor layers are configured to the desired patterns. The electrically programmable reticles are either patterned in continuous forms that have separately applied voltages or in a matrix of rows and columns that are addressed by row and column selects such that desired patterns are formed with the application of a first voltage level and reset with the application of a second voltage level.
