Shaping Light by Diffusing
We speak about diffusers if the radiation from a source is distributed in a more random-like manner to obtain the desired intensity pattern in the target region. This light transformation concept is adapted from holography. LightTrans designs diffusers with deterministic scattering behavior. LightTrans Deterministic Diffuser™ is designed by diffractive optics techniques often combined with standard lens design methods. Deterministic Diffuser™ is well suited for all partially coherent sources like LED and excimer lasers. But also for coherent laser sources they often allow the generation of shaped and homogenized light fields as long as the resulting speckle pattern is not resolved by the detector. Deterministic Diffuser™ technology is a powerful solution to technical and commercial illumination tasks, light pattern generation, and storage and display of information.

- The setup demonstrates how the utilization of sophisticated non-paraxial diffuser design techniques allows one to obtain an amazingly large light pattern – here as example the ‘skyline’ of Jena – at a short distance behind a simple device consisting of a diode laser and a diffusing component.
