Aug. 1, 2014 1.50 Time - Hours Done by Tibi

Worked with Antonio on the Mosquito SS4.
We tested the Ne laser. We wanted to see if we can eliminate the noise or inversion of signal. We arrived at the conclusion that the circulator doesn't pass the red laser. So no light was detected at the exit of the photonic system, on the side of the transducer.

April 10, 2014 4.00 Time - Hours Done by Tibi

Tested different transducers and displacement signal.
Joint-type and microfiber. The SS4 seems to be more sensitive than the Chinese mosquito, we believe this is related to the diameter of the core, SM vs MM.
The first tested microfiber transducer did not work.

April 8, 2014 4.00 Time - Hours Done by Tibi

Worked with Jonathan, made first measurements comparing signal noise

Unplanned Work:

Work event: Work - Technician experimental 2.00 Time - Hours Aug. 21, 2014 Done by Tibi

Worked with Antonio on the Mosquito.
We reassembled the Mosquito in a different way. We used the Chinese photodiode with a MM fiber and ST connector, taking light from a splitter, placed after the PM photonics, in order to see if the fluctuations come from polarization.
The experiment was inconclusive, i.e. still measured background signal fluctuations when the transducer is connected to the Mosquito, probably due to feedback into the laser.

Worked with Antonio on the Mosquito SS4. We did some new tests to solution the problems with signal fluctuation, after the meeting with Luis Renauld.

Made 2 constriction transducers to test the Mosquito SS4

Work event: Work - R&D optics 1.00 Time - Hours June 10, 2014 Done by Tibi

Helped Antonio to install the Mosquito SS4 and retest the photonics. this was required in order to continue the next step of evolution of the Mosquito SS4. See document Mosquito SS4 new development - Interns summer 2014

Process notes:

Assemble and test the photonics layer of the Mosquito SS4. This requires assembling of LD, OD, optical fiber, perhaps a transducer, or a bare fiber and a mobile mirror.
