Abstract
Described examples include a projection device having a light source. The projection device also has a spatial light modulator arranged to receive light from the light source and provide modulated light. The projection device also has projection optics arranged to receive and project the modulated light. The projection device also has a field splitting element between the spatial light modulator and the projection optics, a first portion of the field splitting element being structured to pass at least a first portion of the modulated light to the projection optics for projection at a first focal length, and a second portion of the field splitting element being structured to pass at least a second portion of the modulated light to the projection optics for projection at a second focal length.
