LIGHT MODULATING DEVICE
First Claim
1. A light modulating device, comprising a spatial light modulator, in which a group of at least two adjacent pixels of the spatial light modulator form a macropixel, the spatial light modulator being of a type such that its pixels comprise a variable content, each macropixel being used to represent a numerical value which is manifested physically by the states of the pixels of the spatial light modulator which form the macropixel, wherein for each macropixel a homogenizing element is present in the optical path after the macropixel, the homogenizing element comprising an optical input and an optical output, the homogenizing element being adapted such that output light of the macropixel is entering the optical input of the homogenizing element and is mixed within the homogenizing element and is output at the optical output of the homogenizing element.

Abstract
A light modulating device comprises a spatial light modulator and a homogenizing element. A group of at least two adjacent pixels of the spatial light modulator form a macropixel: The spatial light modulator is of a type such that its pixels comprise a variable content. Each macropixel is used to represent a numerical value which is manifested physically by the states of the pixels of the spatial light modulator which form the macropixel. For each macropixel a homogenizing element is present in the optical path after the macropixel. The homogenizing element comprises an optical input and an optical output. The homogenizing element is adapted such that output light of the macropixel is entering the optical input of the homogenizing element and is mixed within the homogenizing element and is output at the optical output of the homogenizing element.
