Each LaserGaugeŽ system consists of a controller and a sensor. The sensor captures the contour of a surface and transmits it to the controller for processing. The controller runs Virtual Gauges or LGBasic algorithms to extract measurements from the digitized contour, displays the plotted contour if the controller has graphical capabilities and saves the measurements to a file.
Sensors come in two basic configurations: handheld for portable applications and remote for stationary or on-line inspection systems. A sensor's field-of-view (FOV) is the width of the laser stripe imaged by the CCD and it defines the sensor's resolution. The feature being measured, such as a weld, fastener or a gap, must be no wider than a third to one-half of the FOV. Some models offer several FOV options; however, the FOV is built into the hardware design and cannot be changed or modified.
The selection of a sensor is based on several factors: type of application, the FOV and resolution required, size limitations or accessibility constraints, and operator preference.
