An imaging projection system that can project uniform illumination onto a light modular while keeping the point spread function small. A Fourier optical system can be inserted between two uniformization structures so that when light passes the through the system, the light output is uniform both in spatial- and angular space.

Method and system for spatial and angular uniformization of light beams

A projection subsystem for a high contrast projection system is described including three digital micro-mirror devices (MMD) and three prism assemblies and a crossed dichroic prism assembly, the prism assemblies having dual TIR prisms.

Projection subsystem for high contrast projection system

A lens position adjustment system () permits adjustment of the position of a projection lens () relative to a projector () for making a Scheimpflug adjustment. The projection lens () has an optical axis (). The system () comprises: a first support part () for fitting to, or forming part of, the projector (); a second support part () for fitting to, or forming part of, the projection lens (); and a connecting part (). The connecting part () is pivotally connected to the first support part () and pivotally connected to the second support part () and configured to permit independent adjustment of the second support part () relative to the first support part () about two axes of rotation () which intersect, and are perpendicular to, the optical axis () of the projection lens (). A locking mechanism (-) is provided for securing a position of the second support part () relative to the first support part ().
