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 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.

Helped Thiago to transfer the Mosquito program into his computer in order to have him test the prototype. We tested the software on his computer with the Mosquito and it worked. Mission was accomplished. Thiago is now independent to perform experiments, without needing me anymore.

Tested the Mosquito SS4 in a box. The box was prepared by Antonio. I only had to test the optical signal. It doesn't work and I don't know why. I left notes in the R&D document and communicated to Jonathan, Antonio and Francois.

Created VAS entries and linked them to the new Mosquito SS4 document. communicated with the team to log their contributions right there. the idea is to make it easier for them to log their contributions. I also revised all opn processes for the Mosquito SS4 and made some cleanup.

Antonio, Jonathan, Tibi and Francois had a meeting on how to continue the Mosquito project.
It was decided to:
buy a PD circuit with integrated amplifier (TA- transimpedance amplifier)
measure light intensity signal to know what circuit to buy
choose circuit
use a DSP (microcontroller)
Timeframe and tasks
June 10:
test existing Mosquito
choose PD circuit.

Discussed with Antonio about Mosquito development. I told him about what I thought we need to develop in terms of electronics and we discussed about how to package the new Mosquito. I also showed him where to find all the info about recent work on the Mosquito that I did. We discussed around some R&D documents.

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.
