Gregory Edward Gilligan is a notable inventor based in Hastings, MN (US). He has made significant contributions to the field of projection systems, holding a total of 12 patents. His work is characterized by innovative approaches to imaging technology.

Latest Patents

One of his latest patents is a projection system using reflective polarizers. This system comprises a first imaging component, at least a second imaging component, and a color combiner. The first and second imaging components each include an imager and a reflective polarizer that is designed to partially separate a light beam from the imager into a first portion and a second portion. These portions have substantially orthogonal polarization states. The first portions of the light beams are directed in the same direction above or below a plane defined by the second portions of the light beams. The color combiner is configured to combine the second portions of the light beams, which also have substantially orthogonal polarization states prior to entering the color combiner.
