A holographic projection system with an optical wave tracking means (M1, M2) for controlling the direction of propagation of a modulated wave uses a position controller and an eye finder (EF). The object of the invention is to provide a controllable optical wave correction, which is in particular able to compensate deformations of the wave which are specific for the current eye position (PE). In addition to general aberrations, dynamic changes and deformations in the form structure of the modulated and processed wave, which result mainly from changes in the direction of propagation of the directed, optically enlarged and modulated wave effected by a focussing display screen S, shall further be reduced as far as possible. According to the invention, the optical wave correction comprises adjustable wave forming means (WFF) and computing means (CU) which control the optical behaviour of the wave forming means based on position information of the current eye position. The controllable wave forming means are disposed in the optical path between an illumination device for the spatial light modulator means (SLM) and the display screen (S) of the projection system.
