Other work was logged previously as non-production work.
The goal is to build a setup and a protocol to test and characterize the xyz piezo.
The deliverable is a report and piezo specs sheet.
Piezo driver tested
CREATE DESIGN AND PROTOTYPE AND ENTER AS INPUT
Piezo tested is a piezo stack - PROVENANCE
The previous days I mounted an optical fiber stretch sensor on the Piezo.
I also prepared the LabView program for the tests.

Today I worked with Jonathan on mounting the new LED 850nm Mosquito to monitor the piezo motion.
We tried to use the Chinese MM circulator in the Mosquito, instead of the Y coupler/splitter, but no light seems to pass through it. the LED and the PD/TIA were coupled directly to make sure that they functioned properly.
I tried to make a Y coupler/splitter using our microsplicer - fusing 3 fibers together, but I was unsuccessful in the first trial. The second one was not completed today, testing will be done tomorrow.

I had to redo the optical fiber attachment to the piezo. The problem was that the piezo was not connected to the fiber holders and was sliding under protective tape. I had to directly connect the piezo the both ends of the piezo ceramic. This her arrangement was tested succesfully. I also adjusted the gain of the mosquito to increase the swing of the signal. We are using an LED mosquito at 850 nm, with the circuit of a mosquito prototype made by Jonathan for the 1550 nm mosquito. I am also using Frederic D laser driver which I connected to a power supply.
