We present a compact binocular head-up display for integration in a motorcycle helmet. A 2D MEMS-mirror reflecting laser beams enables the formation of a bright image superimposed on the user vision by means of retinal scanning. A 3d-printed prototype including the required optical components is presented and characterized. It fits the morphology of most users thanks to several degrees of freedom accessible to the user for fine-tuning.
MEMS-scanning laser projector have seen tremendous performance improvements in the past year, demonstrating devices with very good performances in terms of size, energy efficiency and image quality that were expected from the theory point of view. The last challenge that was not solved yet is the speckle reduction, which is the main bottleneck for this technology adoption. The paper presents an innovative design to reduce speckle contrast without degrading any other features and benefits of the projection system. The proposed despeckling solution is a single, non-movable part with less than 0.1cc in volume and of 4mm in thickness.
Lemoptix develops next-generation of Micro-Opto-Electromechanical Systems (MOEMS)-based laser scanning and
microprojection technologies and products for professional and industrial applications. Lemoptix LSCAN laser scanning
micromirrors are designed to be integrated by OEM (original equipment manufacturer) customers into a number of
applications such as printers and industrial sensors, enhancing performances and enabling the development of smaller,
higher resolution and lower cost products. Lemoptix MVIEW, world's smallest laser microprojection systems are ideal
for integration by OEMs and ODMs (original design manufacturers) into various demanding applications such as headup
displays in cars or mobile devices. Embedded MVIEW modules will enable the projection of content and information
directly from the device on any nearby surface, enabling users to conveniently view and share information and content
without the typical limitations of physical displays.
