Using the Laser Head in a System
Introduction
The laser head(s), receiver(s), optics, and electronics in a laser
interferometer positioning system measure distance very accurately. This
chapter provides an
example of how the laser head is used in a laser
system.
A one-axis example is used for simplicity
Each axis of a laser positioning system is set up, aligned, and operated in
essentially the same way. A six- axis system is similar to a one- axis
system; therefore, only a single- axis system will be described in this
chapter. Additional axes are then operated like the axis in the example.
Basic steps apply to all laser systems
Specific products (identified by Agilent model number) are used in the
example, but the installation and operation of other Agilent products are
similar.
The example shows the use of PC- compatible electronics and a linear
interferometer.
Regardless of the specific products you are using, the information and
procedures presented in this chapter will help you get started quickly and
easily.
Agilent laser interferometer positioning systems at a glance
Figure 17 shows the components of a typical single- axis Agilent laser
system. All Agilent laser systems combine optics (interferometer and
reflector), electronics, and opto- electronics (laser head and receiver) to
make a highly accurate positioning system.
