Work

Planned Work: (Requirements are ordered by due date)

R&d optics work: 1.00 Time - Hours due May 21, 2013

2013 May 21 (5.5 h + 1.5 h):

prepare 5 joint-type transducers in angle using Ivan's pre-bent glass capillaries. Result: broke one, fried one, one has a damaged mirror. 2 left to connectorize. Connectorization failed. 0 transducer made....

2013 May 22 (4h):

goal: mirror 4 levers, connectorize one transducer.
silvering quality tests: played with number of silver layers and reaction time:
red lever: 3 times one minutes shaking. Intensity = ?
one black strip lever: one time one minute shaking. Intensity = ?
two black strips lever: one time 2 minutes. Intensity = ?

Arranged power supply memories for shrinking:
M1 = 0
M2 = 0.32 A x 0.67 V = 0.2 W
M3 = 0.4 x 1 = 0.4 W
M4 = 0.6 x 0.1 = 0.6 W

Determined ideal length for delivery fiber at the very beginning (before cleaving 1 cm both side) = 16.7 cm

Result: made one pre-bent joint-type transducer.

2013 May 24 (0.5 h):
tested transducer with LED Mosquito: it works

2013 June 5 (7.5 h)
goals: test new LED-Mosquito with amplification + filter
1) signal tests on LED-Mosquito: signal without anything plugged (no delivery fiber): 0.995-1.065 V (average 1030 mV), noise = 70m V.
+ delivery fiber: 1.205-1.125 V = 80mV noise (average baseline 1165 mV), so the delivery fiber increases reflexion of 135 mV.
Reference: with industrial mirror max signal goes to + 10.3 V (note that signal goes up now when light goes back to the PD, it was the opposite before: signal was going down when more light).
Note 2: signal saturates when lever with mirror in front of delivery fiber, so gain is too high.
2) Shrinking trial 1: OK, Shrinking trial 2: failed: shrinking tube didn't stick to the fibers, dust or grease ? Didn't stick even with washing with alcohol.
3) connectorization procedure update:
step 1) verify if chinese ST connector is not clogged. Place the conenctor horizontally on the table and push a stripped fiber in. Don't maintain the connector so if the fiber can't go inside, the fiber won't break, it will just oush the connector.
step 2) assemble the glass capillary and the black plastic cover
step 3) insert the shrunk fiber into the glass capillary
step 4) use the same technique as in step 1) to insert the shrunk fiber free end into the connector
step 5) adjust the gap position relative to the capillary end by gently sliding the capillary. Apply glue on the connector to fix the black cover. Add glue just below the gap between gap and capillary end.
