While AR deployment in enterprise applications is accepted by trading off size, weight, and power consumption, this trade‐off is not accepted in the consumer market.

We have developed an ultra-compact RGB laser light module with an external MEMS mirror. The red, green, and blue laser beams are combined by adapting the laser diode driving signals in the time domain. Article not available.

In micro-electro-mechanical systems (MEMS) laser scanners, the beams reflected by the micromachined mirror may be truncated at various edges in the system, e.g., due to finite size of the reflective mirror surface, at the rigid supporting mirror frame, and at the package of the light source. In this paper the joint effect of such individual beam cl...

We have developed a calibration method for synchronizing the autostereoscopic viewing zones displayed by an array of "trixels", i.e., laser modules with integrated MEMS mirrors. Calibration patterns are projected onto a calibration screen and recorded by a camera. The distortion functions, which map the laser diode driving signals from the time dom...

For many applications of MEMS actuators a well-defined trajectory of the movable device component is crucial when using a simple and inexpensive open-loop controller. We have applied to quasi-statically actuated electromagnetic MEMS mirrors the control technique called "input shaping", which is widely used for systems at the macro-scale and to a le...

We have developed highly compact RGB laser light modules to be used as light sources in multi-view autostereoscopic outdoor displays and projection devices. Each light module consists of an AlGaInP red laser diode, a GaInN blue laser diode, a GaInN green laser diode, as well as a common cylindrical microlens. The plano-convex microlens is a so-call...

We have developed highly compact light modules to be used as pixels in multi-view autostereoscopic outdoor displays. Each light module consists of three laser diodes, associated monitor photodiodes, a cylindrical microlens, and an electromagnetic 1D MEMS mirror. The mirror deflects the collimated light beams to the left and right eyes of multiple v...

State-of-the-art autostereoscopic displays often do not comply with mandatory requirements for outdoor use, because of their limitations in size, luminance, number of 3D viewing zones, and maximum 3D viewing distances. In this paper we propose a concept for a modular autostereoscopic multi-view laser display with sunlight readable luminance, theore...

The ongoing miniaturization of micro-opto-electro-mechanical-systems requires compact multifunctional packaging solutions like offered by the three-dimensional MID (molded interconnect device) technology which combines integrated electronic circuitry and mechanical support structures directly into one compact housing. Due to the inherently large th...

State-of-the-art autostereoscopic displays are often limited in size, effective brightness, number of 3D viewing zones, and maximum 3D viewing distances, all of which are mandatory requirements for large-scale outdoor displays. Conventional autostereoscopic indoor concepts like lenticular lenses or parallax barriers cannot simply be adapted for the...

In this paper the performance of interference alignment is evaluated for the downlink of 3GPP UMTS LTE via the Vienna LTE Link Level simulator. Interference alignment is compared to closed-loop spatial multiplexing, a non-cooperative communication scheme. In order to reduce the computational complexity of solving the interference align-ment problem...
