aLIGO Optical Lever Longitudinal-to-Angle Coupling Coefficients

Document #:
Document type:
E - Engineering documents
Other Versions:
Due to the finite length of the optical levers, and the non-zero angle between the source and detector, there is cross-coupling between longitudinal position of an optic and the pitch/yaw signals of its optical lever. This spreadsheet calculates those cross-coupling numbers.
