About Our Laser Tracker
The In-Place Measurement Services laser tracker is a portable measurement
instrument that takes ultra-precise measurements without mechanical or
environment constraints found in traditional coordinate measurement machines (CMM’s).
Our laser tracker takes measurements by projecting a visible laser beam onto
a mirrored target which
is moved by the operator over the surface being measured. The beam reflects off
the target and retraces its path back into the tracker. Part of the beam goes to an
internal electro-optic subsystem that measures the distance from the tracker to
the target, and part goes to a position-sensing detector that helps guide the
mechanism that steers the beam. Together, the angles of the
axes and the distance of the target from the beam source precisely locate the part being measured. The tracker takes up to
1,000 samples per second for each coordinate point it measures, thus ensuring
accuracy through redundancy and statistical averaging.
The laser tracker is accurate within approximately
0.001 in. at 16 ft, and
provides a working envelope of up to 250,000 cubic feet without being
moved.
The tracker is connected to a computer that runs specialized control
and analysis software. In addition to standard X,Y,Z coordinate data, the
operator can generate interactive 3D graphics that interface with most CAD
programs such as AutoCAD.
Some advantages of In-Place Measurement Services’ FieldCMM technology using
laser tracker equipment are:
 | Ultra-precise measurements without mechanical constraints found in
traditional coordinate measurement machines. |
 | Portable, easy to transport, and quick to setup and use. |
 | Only one person is required for most
operations. |
 | Only one station is required to measure 3-D features. |
 | Provides direct integration with engineered CAD models. |
 | Scans complex surfaces very quickly and accurately. |
 | Saves time in reverse engineering and surface comparisons. |
 | Virtually no limits on size or geometry of part or structure being
measured. |
 | Highly cost effective relative to other measurement technologies. |
