Nowadays high volume, high-cost, and accurate measuring systems are necessary to characterize and test MEMS and MOEMS especially to examine motions, deflections and resonance frequencies that are the distinguishing characteristics of these systems. This paper presents an

Recent progress in the development of compact modulated RGB laser sources enables to set up very small laser projection systems that become attractive not only for consumer products but also for automotive applications like head-up and dash-board displays. Within the last years continuous progress was made in increasing MEMS scanner performance. However, only little is reported on how mass-produceability of these devices and stable functionality even under harsh environmental conditions can be guaranteed. Automotive application requires stable MEMS scanner operation over a wide temperature range from -40° to +85°Celsius. Therefore, hermetic packaging of electrostatically actuated MEMS scanning mirrors becomes essential to protect the sensitive device against particle contamination an...

This paper presents the development of an AMR sensor interface prototype based on the intelligent sensor interface (ISIF) and designed following the platform based design flow. The ISIF is composed by an analog front-end and a digital section. The analog section performs

This micro-opto-electro-mechanical-system (MOEMS) is very important towards the integration into a system on a package of a complete laser projection system. Modeling and simulation of the MOEMS is a key point for the development of the proper micromirror electronic conditioning interface thus reducing time to market and production costs. In literature, there are not exhaustive examples of complete characterizations of 2D torsional scanning micromirrors. The aim of this work is to develop a Simulink model which incorporates the main mechanical and electrostatic parameters of the sensor such as the resonance frequency, the torsional constant and capacitance versus rotation angle characteristic. This model has been successfully verified via experimental measurements and it proved his effectiveness in the development of the relevant electronic conditioning circuitry.
