Non-Contact Laser-Based Vibration Sensor

The discipline of Vibrometery is wide and has many applications, vibrations are present in any mechanical system that involves moving components. So far, the main method to measure these vibrations has been the traditional accelerometer sensor, although it has its limitations and challenges.
Laser Doppler Vibrometers (LDV) were developed in order to address some of these limitations and they offer a non-contact measurement of vibrations by leveraging the Doppler shift effect. Although LDV offers superior accuracy and the benefits of non-contact measurement, this technology has been historically very expensive and not practical for rugged industrial applications.
In this project, we propose to develop an alternative sensor to LDV by utilizing the propriety technology developed by the partner company in the field of RF/photonics. The idea is to design a sensor without the expensive opto-mechanical assembly that is required by LDV. This will enable the industrial partners to commercialize this technology and develop a series of product lines for the global Vibrometery market.
