OMC provides a product selection assistance service for
non-contact distance measurement techniques. The devices in our
database can vary from tens of metres to a few microns in range
while the speed of measurement may be as fast at 500 thousand per
second. The techniques may measure in one dimension only
or provide a full 3-D measurement capability. The methods available vary from
those using light to sound, from interference and time of flight to
triangulation. An instrument costs vary considerably from a few pounds to many
thousand pounds.
