Removal of `zig-zag` in plasma arm expansion optics to ensure beam is not clipped by vessel entrance window
Robust radius of curvature matching requires that the *profiles* (not just the values at the detector) be as closely matched as possible
Added commentary explaining FB imaging system
Finished rudimentary power calculation
Completed max power routine incident on detector - next, need best average max power for robustness to alignment errors
Power maximization with alignment uncertainty working.
Optimal distance from AOM to reference arm focusing lens now accounts for (1) sufficient plasma/reference beam overlap at the detector face and (2) maximal power after satisfying (1)
Only make *one* call to `z_ff(...)` as opposed to two... not as pretty, but it is ~2x faster this way.
Changed the definition of normalized curvature, `dKappa`, to be more consistent with current usage
Updated beam matching plots for easier integration into presentations
Forgot x-axis labels on two of the plots; corrected now
Rost comments and layout for demodulation scheme
VIGO detector not what it appeared - responsivity much higher than expected, so this document tries to explain why
Units: W/cm^2 -> W/mm^2
Routines now allow for scattering from fluctuations of a given `k` from `top`, `midplane`, and `bottom` of tokamak
Deflection angle goes as the sine, not the tangent, of k / k0, as discussed in Dorris thesis (think of diffraction grating and requirement for constructive interference)
Updated diameter routine to account for scattering from fluctuations
Updated to have `source_to_P2()` and `P2_to_detector()` routines
Now allows for dispalcement of beam on P2 due to vibrations
Signal incident on detector - routines for calculating max power and ratio of AC-to-DC power
