Optical Position Sensor Tests on SPS Prototype

1. Tests on Laboratory:

Tests Performed on 14/01/2015:
Folk on free movement as a pendulum (Measurements taken ClockWise and CounterClockWise)

Motivation:
Asses the good status of the optcial disk and Optical Position Sensors Calibration

Outcome:
1. Only Slave sensor could be tested and its signal processed.
2. Disk is OK on the area studied (since it's a pendulum movement a complete revolution is not seen)
3. Alignment of both focusers OK

Script Used:

• Matlab_Script.rar
