Microoptical telescope compound eye.
A new optical concept for compact digital image acquisition devices with large field of view is developed and proofed experimentally and anamorphic lenses, where the parameters are a function of the considered optical channel, are used to achieve a homogeneous optical performance over the whole field of sight.

Thin compound-eye camera.
An artificial compound-eye objective fabricated by micro-optics technology is adapted and attached to a CMOS sensor array and the lithographic generation of opaque walls between channels for optical isolation is experimentally demonstrated. Expand
Artificial apposition compound eye fabricated by micro-optics technology.
By exploring micro-optical design principles and technology, this work has developed an artificial apposition compound eye that consists of an UV-replicated microlens array upon a thin silica substrate with a pinhole array in a metal layer on the back side. Expand
Array projection of aperiodic sinusoidal fringes for high-speed three-dimensional shape measurement
Abstract. Three-dimensional (3-D) measurement systems based on coded-light techniques are conventionally limited by the projection speed, which is typically in the range of a few 100 Hz, resulting inExpand
Artificial compound eyes: different concepts and their application for ultraflat image acquisition sensors
Two different approaches for ultra flat image acquisition sensors on the basis of artificial compound eyes are examined and measurements of the angular sensitivity function are compared to calculations using commercial raytracing software. Expand
Theoretical analysis of an artificial superposition compound eye for application in ultra flat digital image acquisition devices
A new concept for a flat digital image acquisition device for large field of views (FOV) has been developed. Antetypes for the optical system are compound eyes of small insects and theExpand
Design and fabrication of a chirped array of refractive ellipsoidal micro-lenses for an apposition eye camera objective
Apposition compound eye camera objectives are one approach for a vast reduction of the optical system length of an imaging optical sensor. Despite imaging the complete field of view through oneExpand
Incoherent beam shaping with freeform mirror
Beam shaping of incoherent light sources (LEDs, halogen lamps) for arbitrary target light distribution is obtained by a single free-shape mirror. Special design algorithm ensures continuous profileExpand
Automated optimization of non-imaging optics for luminaries
A direct optimization algorithm, which does not calculate the derivatives of the merit function leading to reduced sensitivity with respect to local statistical deviations is realized, and a "red-blue intersection reporting" algorithm is realized as a constraint for optimization. Expand
