Abstract:
1. An expanding chassis for an imaging unit for use in imaging systems having a plurality of imaging units arranged in an array, the expanding chassis comprising: a rigid frame for housing a light engine and related circuitry, and for mounting a screen on a front surface of said rigid frame for use with said light engine; and at least one expandable interface pad on at least one side of said rigid frame; said rigid frame and said expandable interface pad having a combined thermal expansion characteristic that provides an overall expansion in the expanding chassis that substantially matches the expansion of said screen, wherein the interface pad is comprised of a fluid or gas filled reservoir, a deflectable diaphragm in fluid communication with said reservoir, and a piston in contact with said diaphragm, wherein said piston is movable in response to deflection of said diaphragm resulting from volumetric temperature-dependent expansion/retraction of said fluid or gas.
