Abstract
Abstract A device for patterning an imaging member (46) is provided. The device comprises a light source (24) which emits light rays (26). Light rays (26) pass through a collimator lens (28) to collimate the light rays (30). The light then strikes a spatial light modulator (32) which is controlled by a computer (40) to reflect the light (42). The light passes through an imaging lens (44) to magnify the pattern for striking imaging member (46). Imaging member (46) is thus patterned by changing modulator (32) by computer (40).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
A method of exposing an imaging member comprising: a. loading a data set into a first row of spatial light modulator elements, said first row of spatial light modulator elements generating a first image representing said data set; b. exposing a first portion of an imaging member to said first image generated by said first row of spatial light modulator elements; c. moving said imaging member relative to said first row of spatial light modulator elements; d. transferring said data set from said first row of said spatial light modulator elements to a second row of spatial light modulator elements, such that said second row of spatial light modulator elements generates a second image representing said data set; and e. exposing said first portion of said imaging member to said second image.
Claim 2
Independent Claim
132 words
A method of exposing an imaging member comprising: a. loading a data set into a first row of spatial light modulator elements, said first row of spatial light modulator elements generating a first image representing said data set; b. exposing a first portion of an imaging member to said first image generated by said first row of spatial light modulator elements; c. moving said imaging member relative to said first row of spatial light modulator elements; d. transferring said data set from said first row of said spatial light modulator elements to a second row of spatial light modulator elements, such that said second row of spatial light modulator elements generates a second image representing said data set; and e. exposing said first portion of said imaging member to said second image.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein said loading a data set step comprises serially loading said first row of spatial light modulator elements.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein said loading a data set step comprises loading a data set into a first row of a deformable mirror device array.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein said loading a data set step comprises loading a data set into a first row of a liquid crystal array.
