Embodiment Construction

[0061] figure 1 Illumination device 1 is shown schematically and exemplarily for irradiating an object 2 with an illumination pattern. The illumination device 1 comprises first light means 3 for generating a first light beam 4 and an optical medium 5 comprising a diffractive optical element 6 , wherein the diffractive optical element 6 is adapted to generate a first illumination pattern 11 . The first light means 3 and the optical medium 5 are arranged such that the first light beam 4 is directed towards the diffractive optical element 6 for generating a first illumination pattern 11 on the object 2 . The lighting device 1 is suitable for being used for decorative lighting, in particular for domestic use. The object 2 is eg an inner or outer wall of a building, a display, a product to be illuminated for advertising purposes, etc., wherein the illuminating device is adapted to illuminate the object decoratively.

[0062] The first light device 3 comprises a laser for generati...

Abstract

The invention relates to an illumination apparatus (1) for illuminating an object (2) with an illumination pattern, in particular for decorative lighting. The apparatus comprises a first light device (3) for generating a first light beam (4) and an optical medium (5) comprising a diffractive optical element (6), wherein the diffractive optical element (6) is adapted to generate a first illumination pattern (11) and wherein the first light device (3) and the optical medium (5) are arranged such that the first light beam (4) is directed to the diffractive optical element (6) for generating the first illumination pattern (11) on the object (2). A diffractive optical element can be written onto an optical medium such that the diffractive optical element has sub-micron features, thereby allowing to increase the spatial resolution of the illumination on the object in comparison to using a LC-SLM or a LCoS for illuminating an object.

Description

technical field [0001] The invention relates to an irradiation device, an irradiation method and an irradiation computer program for irradiating an object. The invention further relates to an optical media writing device, an optical media writing method and an optical media writing computer program. Background technique [0002] Illumination devices that produce various lighting effects are used in hospitality applications such as in hotels and restaurants, as well as in creating ambiance at home, in hospitals, in museums and in store lighting concepts. The light generated by the laser is directed towards a diffractive optical element (DOE) to generate an illumination pattern that illuminates the object. Pixelated microdisplays such as liquid crystal spatial light modulators (LC-SLM) or liquid crystal on silicon (LCoS) allow DOE by feeding computer data to the display in real time, a technique known as computer-generated holograms. [0003] LC-SLMs have a typical pixel siz...
