Abstract

The optical device (110) according to the invention comprises a laser source (113) to provide laser light (112) for preparing a holographic element, an optical reflection element (114) arranged in the propagation path of the laser light, and a beam-splitting element (116) arranged in the propagation path of the laser light behind the optical reflection element. The beam splitting element comprises, in the direction of light propagation, a base surface (116a) and two lateral surfaces (116b1, 116b2) forming an angle with one another, said base surface faces the reflection element and is configured to direct laser light striking on the base surface into the beam splitting element. The lateral surfaces face the photosensitive photoplastic substance and refract a portion of the laser light striking on said lateral surfaces from the beam splitting element towards the photosensitive photoplastic substance, thereby exposing said photosensitive photoplastic substance to an illumination of periodic intensity distribution. The beam-splitting element further comprises a region (116d) that transmits a portion of the laser light entering through the base surface towards the photosensitive photoplastic substance essentially without inducing a change in its propagation direction. Each of the lateral surfaces or the region that transmits without inducing a change in the propagation direction carries or is optically coupled with a polarization-setting element, wherein said polarization-setting element is configured to render the polarization state of the laser light portion exiting through the lateral surfaces and the polarization state of the laser light portion exiting through the region that transmits without inducing a change in the propagation direction orthogonal to one another.
