=== Memo related to tilt sensor===

The tilt　sensor is supported by JSPS Core-to-core.
The sensor can measure d\theta directly.
The principle is Mach-Zhender interferometer.
One tilt sensor was installed to MCE. For other two, no space for install.
A difference between OptLev and tilt sensor will be checked.
There are three tilt sensors; one installed.
No phase wrapping(Probably)
Absolute tilt angle can be measured
Dina mic range (5 mrad) is bigger than OptLev's(<1 mrad).
Install is not easy comparing to OptLev install, because there are 4 beam lines.
