Integrated electro-optic package for reflective spatial light modulations

摘要

An array (10) of reflective LCSLM pixels formed on a substrate (11) with a light polarizing layer (45) positioned between the array (10) and a light source (52). An overmolded housing (44) defining an optical waveguide (42) having a light input, a light output, and a mirrored surface (15) directing light from the input toward the output, the polarizing layer (45) being mounted to allow light passing into the optical waveguide (42) to pass therethrough. The light source (52) provided to direct light through the polarizing layer (45) and evenly illuminate the array (10). Light reflected from the array (10) is directed onto the mirrored surface (15) of the optical waveguide (42). A diffuser (47) at the output forms an image plane for the reflected light. Electrical connections (28) are made from the array (10) to a circuit board (46) on which it is mounted. All components are encapsulated by the overmolded housing (44), having leads formed in the housing (44) to provide external contacts (12, 27).
