Measurement and modeling of microlenses fabricated on single-photon avalanche diode arrays for fill factor recovery

Edoardo Charbon, Juan Mata Pavia, Martin Wolf

Single-photon avalanche diode (SPAD) imagers typically have a relatively low fil factor, i.e. a low proportion of the pixel's surface is light sensitive, due to in-pixel circuitry. We present a microlens array fabricated on a 128x128 single-photon avalanch ...

A Practical Method for Measuring the Spatial Frequency Response of Light Field Cameras

Sabine Süsstrunk, Loïc Arnaud Baboulaz, Damien Firmenich

The spatial frequency response (SFR) is one of the most important and unbiased image quality measures of a digital camera. It evaluates to which extent a lens/sensor combination can resolve scene details. In this paper, we propose a simple and practical me ...

Curved Holographic Combiner for Color Head Worn Display

Jürgen Brugger, Christophe Moser, Eric Tremblay, Victor Javier Cadarso Busto, Jonas Grossenbacher, Arnaud Mader, Seyedpayam Vahdati

A volume hologram recorded with a lens array is proposed as a color transflective screen for Head Worn Display (HWD) systems. Design, fabrication as well as proof of concept are reported. Light from a single MEMS-based projector is efficiently diffracted t ...

Phase Anomalies in Micro-Optics

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We present a comprehensive review on the latest research activities that explore the Gouy phase and indicate the recent experimental progresses for its observations in studies that rely on a longitudinal-differential interferometer. The latter is a far-fie ...

On Micro Optical Elements for Efficient Light Diffusion

Roland Andreas Bitterli

Efficient light management is one of the key issues in modern energy conversion systems, be it to collect optical power or to redistribute light generated by high power light emitters. This thesis touches mainly on the subject of efficient light redistribu ...

Curved Transflective Holographic Screens for Head-Mounted Display

Jürgen Brugger, Christophe Moser, Eric Tremblay, Arnaud Mader, Victor Javier Cadarso Busto, Jonas Grossenbacher, Seyedpayam Vahdati

A volume hologram recorded with a lens array is proposed as a transflective screen for Head Worn Display (HWD) systems. Design, fabrication as well as proof of concept are reported. Light from a projection system, with similar properties to one mounted on ...
