A projection device includes one or more deformable mirror arrays ( ) arranged to spatially modulate incident light. A totally internally reflecting surface ( ) is arranged to direct light to and from the deformable mirror array ( ). The device may include one or more dichroic layers ( ) arranged such that the light incident on each dichroic layer ( ) is substantially normal incidence to the layer.

Projection device comprising a prism system including at least one totally internally reflecting surface at a boundary between two members of different refractive indices within the prism system

A projecting display system includes a light source ( ) which produces light which is spatially modulated by a number of spatial light modulators ( ). A splitting means ( ) is provided in the light path between the light source ( ) and the spatial light modulators ( and ) such that the overall luminous flux produceable by the system is not determined by the maximum luminous flux which each spatial light modulators ( ) can accommodate.

Display system

A projecting display system includes a light source (,) which produces light which is spatially modulated by a number of spatial light modulators (,). A splitting means (,) is provided in the light path between the light source (,) and the spatial light modulators (,and,) such that the overall luminous flux produceable by the system is not determined by the maximum luminous flux which each spatial light modultors (,) can accommodate.

A projection device which includes a plurality of deflectable mirror arrays arranged to spatially modulate incident light. A totally internal reflecting surface is arranged to direct light to and from the deformable mirror array. The device includes on or more dichroic layers arranged at an angle relative to the incident light dependent on the spread of angles on the incident beam relative to the optical axis. Additionally or alternatively, the totally internally reflecting surface may be arranged to direct non-spatially modulated light towards a beam dump.
