R&d optics work: 1.00 Time - Hours due Oct. 31, 2013

Created a low cost optical tape sensor that can be put on different structures to detect bending.
We'll apply it first on a hockey stick.

See project page
http://www.sensorica.co/home/projects/smart-sports-equipment

Started on Friday 27, 2012 After we created the prototype and made the demo for Zhu (Canadian Space Agency, beam deflection sensor) we realized that this device works in stretching and compression. I had the idea to create a very simple and low cost tape sensor using 250 um diameter PMMA fiber and kapton tape. The goal of this experiment was to build the first such prototype and test it. See design https://docs.google.com/drawings/d/17Wb68vkZPeV5jz1GJDJG-TXER2Ofy-1wyndfQbkgp10/edit The device was built and successively tested. See the video made with Daniel http://youtu.be/yKvdryt1iKk

04 JUNE 2013
Worked on the setup to fabricate the low cost Tape transducer. I continued in the same direction from where I left it. The device is now almost done, need to take some pictures and document how it works. This is still a prototype device, to produce a few of them in a systematic matter and test them.
I will use the enhanced LED 850nm Mosquito to test it. I need to make a project presentation to SENSORICA about this, in a week.

05 JUNE 2013
Did some mechanical work on the fabrication device. I finally put in place the micrometer screw and 2 springs to move the working plate. It seems to be solid. After this, I shifted my attention to the Y connector for the 250um diameter PMMA fiber. I created a separate labnotes where I marked 7 hours of work on this. The main problem was to create a mold/stamp for PCL, from which I make the connector. The idea is to stamp the Y grove into PCL, place the fibers into the grooves and apply optical clear epoxy to hold the fibers aligned in place. I started with clay, and moved to etching aluminum.

10 JUNE 2013
Produced a new low-cost tape sensor using Francois' design.

14 JUNE 2013
Created documentation for the low cost tape sensor, adding stuff on the website, and updating the document.
Gave training to Ronan on the Tape Sensor. I also created a labnote for him to collaborate on this project.

16 AUGUST 16, 2013
Worked with Rodrigo on a new tape sensor design. We are trying to implement the idea of optical gearing. See concepts here
https://lh4.googleusercontent.com/VLhJE8ggBraByZLK-WyucfEWbLdz5ScYHO-RZ8t_dNo=w362-h217-p-no
One design use a concave lens (perhaps made with PDMS, using rounded lass rod/fiber as mold). See idea here
https://lh3.googleusercontent.com/fAnLoT_j3kPJST15bq41oYahT-XAuZWAX2RcJCSAXbQ=w345-h207-p-no
The other one uses a scattering (+ absorbent) medium within the gap between two fibers, using index matching gel with micron-size particles (silica powder or carbon powder).
See the design for the second choice here.
https://lh5.googleusercontent.com/TKaGjSu5k_NSM3qCjCIF6-cbXahWO_Ea8N91XjANrnY=w124-h207-p-no
Rodrigo and I designed an experiment to compere intensity variation with gap between an air gap and a scattering (+absorbent) medium. We are going to create the setup and perform the comparison next week. The deliverable will be a white paper. See idea here.
https://lh3.googleusercontent.com/rOv894jxwoewGojdu-sDyKQbzR5qUljyr3EuqZUP6Ko=w345-h207-p-no

23 AUGUST 2013
Worked on the low cost tape sensor with Rodrigo, helped him with the optical setup for some exploratory testing of optical gears. We are using 1mm PMMA fiber for these tests. This is in continuation of the previous work.

Worked on the setup to fabricate the low cost Tape transducer. I continued in the same direction from where I left it. The device is now almost done, need to take some pictures and document how it works. This is still a prototype device, to produce a few of them in a systematic matter and test them.
I will use the enhanced LED 850nm Mosquito to test it. I need to make a project presentation to SENSORICA about this, in a week.

Did some mechanical work on the fabrication device. I finally put in place the micrometer screw and 2 springs to move the working plate. It seems to be solid. After this, I shifted my attention to the Y connector for the 250um diameter PMMA fiber. I created a separate labnotes where I marked 7 hours of work on this. The main problem was to create a mold/stamp for PCL, from which I make the connector. The idea is to stamp the Y grove into PCL, place the fibers into the grooves and apply optical clear epoxy to hold the fibers aligned in place. I started with clay, and moved to etching aluminum.

Created a low cost optical tape sensor that can be put on different structures to detect bending.
We'll apply it first on a hockey stick.

Started on Friday 27, 2012 After we created the prototype and made the demo for Zhu (Canadian Space Agency, beam deflection sensor) we realized that this device works in stretching and compression. I had the idea to create a very simple and low cost tape sensor using 250 um diameter PMMA fiber and kapton tape. The goal of this experiment was to build the first such prototype and test it.
