Application Note: MEMS - Reliable Helpers In Motor Vehicles

Laser Vibrometry as an Indispensable Tool in MEMS Development

50 years ago, "sensor technology" in a car was limited to a handful of mechanical, or at best, electromechanical instruments, such as tachometers or rev counters. In contrast, a modern car, has numerous microprocessor-controlled electronic sensors and actuators that carry out complex measurement, monitoring and control tasks. An indispensable tool in the development and production of these silent assistants are modern, non-contact optical metrology processes.
