General Description
The Profiler 2 is a high-precision profile measurement sensor.
The characteristics of this product are shown below.
• This product achieves high-precision measurement by emitting a band-
shaped laser beam and using a light-plane-intersecting method that
triangulates the reflected light.
• Settings can be configured, measurements can be performed,
and output can be generated from the sensor. No amplifier unit
or other auxiliary devices are necessary.
• Various settings can be set from the sensor or from the dedicated setup
software (PRO2-navigator).
• It is possible to measure 4 areas with a single measurement. For each
area, there are 13 types of measurement functions to select from.
• There are 4 camera modes available. This enables you to select
the optimum settings to match the environment of the production line
to be measured and the state of the target object.
With the light-plane-intersecting method, the reflected light from the
emitted band-shaped laser beam is received by the light receiving element
(CMOS), and the profile is then measured from the resulting image data.
With the light-plane-intersecting method, two processes are used to
determine the height and position.
• Triangulation: To determine the height, this process obtains the received
light waveform (the waveform of the reflected light) for each vertical line
of the image.
• Projection transformation: To determine the horizontal position,
this process mathematically calculates the actual position from
the image data.
