Title:
OPTICAL WAVE CORRECTION FOR A HOLOGRAPHIC PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO2008092892
Kind Code:
B1
Abstract:
A holographic projection system with an optical wave tracking system (M1, M2) which sets the propagation direction of a modulated wave uses a position control system and an eye finder. It is the object of the invention to provide an adjustable optical wave correction system which compensates for deformations of the wave which are dependent in particular on the current eye position (PE). Here, besides general aberrations, largely dynamic changes and deformations in the form structure of the modulated and conditioned wave are intended to be reduced, which result predominantly from changes in the propagation direction of the aligned, optically enlarged and modulated wave on a focusing display screen S. According to the invention, the optical wave correction system comprises adjustable wave form means (WFF) and computer means (CU) which set the optical behaviour of the wave form means using the positional data from the current eye position. The adjustable wave form means are located in the light path between an illuminating system for the spatial light modulation means (SLM) and the display screen (S) of the projection system.
