Lentickle model for C1

Scripts are found in iscmodeling/LentickleC1

Purpose

  • To get the OLTs
  • To get noise budget
  • Sensing matrix with loops

Main script to execute

C1lentickle.m builds the Optickle model, then inclides the loops defined by C1cucumber.m The Optickle model for C1 is same as Kiwamu's scripts, optC1:

  • optC1.m ... Optickle model
  • paramC1DRMI.m ... physical parameters for optC1
  • probesC1_00.m ... probes of the model

C1cucumber setting

  • Sensors
    • REFL 3I1
      REFL 3Q1
      AS I2
      AS Q2
      AS DC

  • Control Filters

ZPK(10, 1000, 1)* ZPK(5, 1, 5)

ZPK(10, 1000, 1)* ZPK(50, 1, 50)

ZPK(10, 1000, 1)* ZPK(50, 1, 50)

bodeplot of the filters These filters already have pendulum compensation. Therefore in cucumber, you don't need the pendulum compensation (mirrFilt) matrix. Here we use a flat (unity) mirrFilt.

* Mechanical transfer function dampRes = [-0.1 + 1i, -0.1 - 1i];
opt = setMechTF(opt, 'IX', zpk([], par.w * dampRes, 1 / par.mass));

Results

  • OLT

  • Frequency noise TF

  • Amplitude noise TF

  • Transfer functions from each optics to each DoF
