Check pupil displacement con vecchie pupille

3.4.1 pupil position vs. system rotator rotation

Ripprendiamo dall'inizio la misura del wobble della pupilla interotta ieri sera
Boardsetup = 15 May 10 - lbt_Walign

CCD frame rate 200 Hz modulation 6V@200Hz (20 lambda/D))

20100525_173429 reconstructor

10:15 We found a problem with the AGW rotator (got stuck) going to 60 degrees, to restart we had to restart MCS which reset the ASM.

After re-starting the pupil was no longer visible.

saved board setup Retroreflector board setup 24 Sep 10

10:30 Re-centered the board with stages to (x,y) -75.9 34.3

Sequenza misura per ogni posizione di derotatore.

10:40 (3.4.1) pupil position accepted

3.4.2 'actuator sub-aperture registration - pupil fine centering'

acquired dark

increasing intensity of reference source (5000 ph/subap)

adjusting cube rotator by 0.1 deg steps to gurantee that the outgoing beam is fully illuminating the AS

10:50 closing loop (gain 0.1)

diameters 29.4-29.7 lato medio 35.9

saving flat save shape flat_200_100924

reducing modulation to have 3 lambda/D @1000 Hz (using WFS Control GUI)

checking filter dichroic 600-1000 nm

source intensity to max (1200 ph/subap)

increasing gain to max gain 0.2 (some instability observed)

relative rotator position increased by 0.1 deg (some instability observed)

11:15 changing reconstructor to 400 modes 20100525_185716

increasing gain to max gain 0.3 (some instability observed)

283.45 deg absolute position of internal rotator with AGW rotator at 0 (estimated by looking at instabilities on WFS at outer edge)

changing camera lens position at y 7 and -12 shows instability, at x -38 and -47 (chosen x,y=(-40,-4)

old values for rotation rotation 284 deg

11:26 (3.4.2) fine pupil position accepted: rotation 283.45, camera lens x,y=(-40,-4)

3.4.3 'pupil acquisition'

image on IRTC is not centered in the small field, decided to use the offloading mechanism to re-center the image

11:30 testing the LO offload mechansim, the loop does not seem to work, the focus applied by ASM increases with time.

decided not to wait for the fix for the LO offloading and do a manual offloading by moving translation stage and compensating with hexapod.

new hexapod position -0.115, 1.9205, 3.602, -345.58, -49.48 0

new stages position -75.2, -35.7, 45.0

Mod = 6V@100Hz

A cloop centriamo le pupille sulla posizione trovata in precedenza.

Acquisizione a cloop delle pupille con raggio grande (+6pix sul diam nell'algoritmo di acq) per poi essere hottizzate
20100924_200344

Si lancia il processo di hottizzazione caricando le nuove pup giganti e premendo il pulsantino PUP sul WFS control GUI ma a modulazione 3V@100Hz perche a 6V venivano dei pattern interni che non si riuscivano ad eliminare alzando la soglia.
