MEMS EVALUATION KIT
The DM3102 enables the evaluation of Maradin’s laser based projection core components, including MAR1110 – 2D MEMS scanning mirror, MAR2100 – MEMS drive and control IC, and the MAR3102 – reference design to incorporate Maradin’s proprietary laser timing algorithm. The DM3100 shortens the development time, enables flexibility and a fast demonstration of laser projection based on Maradin’s technology.
HOW THE LASER SCANNING PROJECTOR WORKS
The MAR1110 is a dual-axis MEMS based scanning mirror targeted for miniature laser projectors and laser steering applications. It is based on industry-leading MEMS technology with novel and precise actuation schemes. The innovative MEMS device combines a fast electro-static actuator and a powerful electromagnetic actuator, which yields peak performance under varying conditions.
The MAR2100 is a Driver and control IC for Maradin’s MAR1110 dual-axis MEMS based scanning mirror. MAR2100 is targeted for miniature laser projectors and laser steering applications. MAR2100 drives and controls Maradin’s MAR1110 dual axis scanning mirror and generates the timing signals to synchronize the laser module through the Host, also called a Data Manipulator. As MAR1110 scanner has two uncoupled actuators – one for horizontal scan and one for vertical scan, MAR2100 controller IC supports both drivers.
The MAR1110 scanning mirror, combined with the MAR2100 controller IC, from the projection module of the system. A general block diagram of such systems is depicted in the animation below.
