Description of Work Term
It was an excellent opportunity to work under the direct supervision of the professor. During my work term, I learnt using different programming and design softwares efficiently. I was able to solve problems related to different projects using programming languages such as LabWindows/CVI and LabView.
I learnt and developed different project management skills, book keeping, and exercised my creative abilities. It was exciting to see interactions between different hardwares such as high speed cameras, data acquisition cards, stepping motor, signal generators etc., while developing programs for them. I learnt techniques to solve problems on the basis of trial and error, assumptions and make decisions based on techincal knowledge. I was able to practically apply design skills and implement theory learnt during my degree. It also gave me an opportunity to openly discuss and represent ideas to the supervisor and receive constant feedback as an engineer during my work term. Indeed, a brilliant opportunity to experience research environment which has also motivated me to learn more and do research for a post-graduation degree.

Dental Strain Imaging System
Scanning Particle Tracking System
This system was designed to track micro-fluid particles by scanning a fluid flow channel with a high speed camera. The main aim was to develop a standalone program that could synchronize data acquisition card and high speed camera required for tracking the micro-fluid particles and design a model of the workbench.
List of tasks:
Programming:
- develop code to operate high speed camera on LabView which would allow capturing images of micro-fluid particles
- develop code to produce multi-signals via DAQ card to operate piezo-actuators for focusing in and out of white light
- develop code to synchronize high speed camera and piezo actuator through operating DAQ card using LabView which would allow the capturing images of micro-fluid particles while synchronously moving the piezo-actuator
- develop similar code using LabWindows/CVI
Design the workbench so that it would:
- allow easy assembly of the 3D stage, camera, piezo actuator
- have easy linear motion of the camera for focus
- make CAD drawings of the custom parts for production use
Dental Strain Imaging System
This system was designed to measure strain on an orthodontic bracket using high resolution camera when a load is applied through the torque wire. The main aim was to develop a standalone program that would allow such functions and design a model of the workstation.
List of tasks:
Programming:
- develop code to operate high speed, high resolution camera on LabWindows/CVI which would allow capturing images of the orthdontic bracket
- develop code to produce multi-signals via DAQ card to operate piezo-actuators for focusing in and out of white light
- perform correlation between subsequent images required for the use in the measurement of the strain
- perform correlation between subsequent images required for the use in the measurement of the strain
- develop code to operate inclinometer for angle measurement
- develop code to synchronize the camera, servo-motor, inclinometer and piezo-actuator through operating DAQ card using LabWindows/CVI
- this would allow the measurement of strain on the bracket through grabbing images from the camera while synchronously applying the load through the servo-motor
Design the workbench so that it would:
- allow easy assembly of the 3D stage, camera, bracket
- have easy linear motion of the camera for focus
- allow easy attachment of the servo-motor to the assembly
- make CAD drawings of the custom parts for production use
