Chapter 4 Angular Measurements
Angular Position Measurements
To obtain the greatest accuracy possible, you must account for
environmental factors such as ambient temperature and humidity. If you
are not using sensors, follow steps 7 through 9 in "Setting Up for the
Measurement" in Chapter 2. If you are using sensors, follow the
instructions in "Placing and Using the Sensors" in Chapter 2.
NOTE
Changes in the interferometer's or the reflector's temperature will
affect the accuracy of your measurements. To minimize this problem,
(1) avoid excessive handling of the optics, and (2) keep the optics away
from sources of heat and cold, such as air vents.
You are now ready to mount and align the precision index table and optics
on the target machine.
