Abstract
An additive manufacturing system includes at least two photoconductor plates attached to a substrate. Each photoconductor plate can include separate the Linear Electro layers and transparent conductive oxide layers.
Claims18
A light valve for patterning incoming laser beam, comprising:
- a substrate;
- and
- at least two photoconductor plates attached to the substrate, wherein the at least two photoconductor plates attached to the substrate are laterally positioned with respect to each other and are polished as one part to have uniform thickness across the at least two photoconductors.
An additive manufacturing system, comprising
- a laser light source to form a laser beam;
- a light valve supporting two-dimensional patterning of the light beam, the light valve comprising a substrate and at least two photoconductor plates that are attached to the substrate, wherein the at least two photoconductor plates attached to the substrate are laterally positioned with respect to each other and are polished as one part to have uniform thickness across the at least two photoconductor plates.
