Mitacs Postdoc Internship (Calgary, AB) – Novel vibrometer development
Desired Start Date: ASAP
Mitacs Program: Accelerate
Project Length: 1 year
Location: Calgary, AB
No. of Positions Available: 1
A start up company from Calgary, AB that has developed a unique IP for innovative vibrometer design. We’re looking for a talented and motivated individual to help develop a prototype that will be tested at the facilities of our large industrial partner.
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 of the laser’s wavelength induced by the target’s vibrations. 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 to LDV by utilizing the propriety technology developed by the partner company in the field of RF/photonics. The idea is to eliminate the interferometric front end and to design a vibrometer without the expensive opto-mechanical assembly that is required by LDV. The successful applicant will have the opportunity to work on an exciting first of its kind technology with deep impact on the Vibrometery industry. The developed sensor will be tested both in the lab and in the field in collaboration with a major industrial partner with global presence.
