Kazuhiro:
This is a plot I showed today.
・There are two candidates of the PC configuration (one beam scanning and two beam scanning)
・In the case of one beam scanning, the SNR becomes better since the reference beam is fixed on the center of the beam (only the test beam is scanned). However the contrast defect happens by interference between two different beam angles.
・The calculation shows several fringes happens around the beam edge (r=1mm; since beam radius is 833um) when the distance between PD and scanner is 20 cm.
・This will be discussed with Bas next week, and we will decide the final optical configuration.
