Ottimizzazione gain con misura gain ottico

Modo iniettato nel loop: defocus oppure modo 100
Ampiezza: 1 nanometro
Frequenza: 50 Hz oppure 100 Hz

Plan:

  1. misura senza disturbo del segnale di defocus con gain ottimizzato
  2. stessa misura con disturbo
  3. misurare le due potenze del modo e farne il rapporto
  4. riscalare il gain secondo il rapporto trovato

Detect oscillazione tramite comandi del secondario

Facciamo oscillare apposta il loop e salviamo i comandi del secondario per vedere se c'e' qualcosa di facilmente detectabile che possa dirci quando il loop sta oscillando
