Abs. Len. Meas. ~ analysis of the TEM01 scan |

Analysis of the data on August 3th ~ Part 2
o I already have reported that the resonant freq of TEM10 and TEM01 split.
o Again, note that TEM10/01 were arranged almost in the horizontal/vertical by the observation of the video.
o The peaks of TEM10 and TEM01 were fitted with the same method as of TEM00.
o The peak freqs were:
f_TEM10: 5087040 Hz +/- 20 Hz
f_TEM01: 5068322 Hz +/- 15 Hz
The split is 18.7kHz.
o The additional parameter from the previous entry:
f_TEM00: 3879252 Hz +/- 9 Hz
L_yarm: 38.6462 m +/- 0.0003 m
o Radius of curvature
Rx = L /(1-Cos^2(Pi (f_TEM10 - f_TEM00) / (c/L/2) ))
Ry = L /(1-Cos^2(Pi (f_TEM01 - f_TEM00) / (c/L/2) ))
from these formula we get the value
Rx = 56.1620 +/- 0.0013 [m]
Ry = 57.3395 +/- 0.0011 [m] |
