5.3.2 - 54862_LeBrun_Square Wave Trajectories_Description

Waveform Graph 8 : Electric field excitation signal monitor (Applied E-field)
Waveform Graph   : QPD X-axis signal(parallel to E-field)
Waveform Graph 2 : QPD Y-axis signal(Orthogonal to E-field)

00 ~ 02 sec : Trapped particle Brownian motion
02 ~ 05 sec : First, Square wave E-field exitation along the X-axis
05 ~ 06 sec : Trapped particle Brownian motion (zero E-field again)
07 ~ 14 sec : Second, Square wave E-field exitation along the X-axis
15 ~ 24 sec : E-field amplitude changing 
25 ~ end    : Trapped particle Brownian motion (zero E-field again)
