4.2.2_4.3.2_4.6.2_4.7.2 - 54862_LeBrun_BeamPositioning_Loading_Description

00 ~ 04 sec : Resting particles
04 ~ 05 sec : Laser filter removal to locate the beam focus on the screen
06 ~ 10 sec : Laser spot image on the CCD
11 ~ 21 sec : Focus moving back and forth to find focal position
22 ~ 27 sec : Laser filter back
28 ~ 41 sec : Beam positioning to the target particle (Inserting arrow for the target particle)
at   45 sec : Pulsing and loading the target particle in to the levitation position (particle blurr-can be used for 4.3.2)
46 ~ 52 sec : vertically translates the levitated particle up (about 1 mm- can be used for 4.6.2)
53 ~ 63 sec : Reducing the laser power to transit the particle into the nominal trapping position.
at   64 sec : Trapped particle (transition complited- can be used for 4.7.2)
66 ~ 70 sec : positioning the trapped particle
71 ~ end    : vertical moving to the measurement position (about 9 mm above the substrate)
