10703A Retroreflector - HP 5501A Operating And Service Manual

2.4 MULTlAXlS MEASUREMENT SYSTEMS
The system is designed to measure up to six independent axes with any combination of inter-
ferometers and retroreflectors. In general, the laser measurement concepts discussed above
apply equally to any multiaxis measurement system (see Figure 2-4).

Figure 2-4. M ultiaxis Measurement System
The multiaxis system is similar to the basic measurement system shown in Figure 2-7 with the
exception that a beam splitter is introduced in the laser beam to provide a second axis of mea-
surement. The X and Y axes are completely independent and generate separate measure-
ment signals. These X and Y measurement signals are compared individually to the reference
signal by the electronics to provide displacement data for measurement or control applications.
Additional beam splitters can be introduced along with corresponding interferometers, retro-
refectors, and receivers to provide up to six measurement axes.
