TEST PSF.

IMPROVE PSF PERFORMANCES OPTIMIZING THE ADC POSITION.

Procedure: taking images from the ccd47 at close loop and changing the ADC1 position.
analyse the images on line.

PSF 1

FW1:600-1000
FW2: 850-10

ADC1:-5
PSF 2

FW1:600-1000
FW2: 850-10
ADC1:-10
PSF 3

FW1:600-1000
FW2: 850-10
ADC1:0
PSF 4

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:0
PSF 5

FW1:600-1000
FW2: 850-10
ADC1:-5

nota: at ADC1:-10 it looks bad from the viewer

PSF 6

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:5

PSF 7

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:0
Focus Z: 62

slopenull acquired in the folllowing way

1) close the loop at initialposition F=61mm

2) open the loop

3) move Z stage to 62mm

4) acquire slope null as soon as possible.

5) close the loop with stages at 62mm using the acquired slope null

PSF 8

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:0
Focus Z: 62 !!!!!!!!!!!!

repetition of psf7

FWHM = 1.5 DL FWHM

PSF 9

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:0
Focus Z: 61.7 !!!!!!!!!!!!

si passa alla configuraziuone WFS ovvero luce diretta sul WFS 8no double pass sul adsec)

psf10
PSF 10

NModes:400
TT:4
FW1:600-1000

fwhm 1.65 lambda/ D

PSF 11

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:-2 ma posizione variabile per via del backlash (isteresi)

Z stage a 54.2

fwhm 1.5 lambda/ D

PSF 12

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:-2 ma posizione variabile per via del backlash (isteresi)

Z stage a 54.5

fwhm 1.5 lambda/ D

psf piu tonda con dei simil anelli di airy questa pare la meglio.

PSF13 idem

PSF 14

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:-2 ma posizione variabile per via del backlash (isteresi)

Z stage a 54.7

fwhm 1.5 lambda/ D

psf peggiore con una piccola spalletta

PSF 15

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:-2 ma posizione variabile per via del backlash (isteresi)

Z stage a 54.6

psf peggiore come intenzita max

SF 6

NModes:400
TT:4
FW1:600-1000
FW2: 850-10
ADC1:-2 ma posizione variabile per via del backlash (isteresi)

Z stage a 54.5

fwhm 1.5 lambda/ D

psf peggiore con una piccola spalletta
