Profiling Measurement – Shape and Surface Inspection
Laser profile measurement
Laser profiling of an object or target can be done with all Acuity sensors. Typically, laser scanners are most commonly used for 2D & 3D shape profiles of targets. The AP820 is commonly used to profile the surface of targets to provide flatness measurements, measure for defects & errors, and to monitor quality control. Profile sensors perform very well on shiny or jagged targets and in environments with high ambient light. The profile sensor’s high profile rate, auto gain and high dynamic range allow for measurement in complex applications, even edge scanning on sharp targets.
Single point sensors are often used for road profiling and tire profiling. A special version of the AR700 laser displacement sensor was designed to meet the high demands of road profilers. Laser profiling measurement is a very broad category. View below our many different applications in which Acuity laser sensors have been used to measure and profile targets. This application list is not intended to be exhaustive, contact Acuity for your profile measurement application.
Aluminum Billet Scalping
Acuity’s AP820 is used to profile aluminum and steel billets with high repeatability and speed before scalping. Several Acuity AP820 laser scanners can be mounted in parallel to cover the whole width of the ingot with one scan.
AP820 Laser Line Parallel and Flatness Measurement
A large US manufacturer has an application where they need to align 2 painted metal surfaces to be parallel to one another very accurately and quickly. By using the AP820-240 model which has a laser line length of 120 mm the laser line is place across the 2 metal surfaces.
Bow and Warp Measurement of Silicon Wafers Using Confocal Sensors
In the production of silicon wafers, manufacturers are particularly concerned with bow, warp and overall flatness of the substrates. Wafer manufacturers use confocal sensors in their custom inspection systems to precisely measure the 2D flatness profile of each wafer.
Detecting Circuit Board Defects
Circuit boards have complex designs and their sizes are becoming tinier and tinier. Companies that specialize in PCB inspection systems need ultra-precise measurement sensors to profile tiny features like holes, solder joints, pin locations, etc.
Fast and Accurate Angle Measurements
Many manufactures have a requirement to accurately measure the angles of their products on line and adjust the process to reduce waste.
Laser Height Pole Measurement
Effectively moving oversized loads requires precautionary measures to ensure safety. This is particularly necessary when it comes to route surveys. A crucial element to maintaining precautionary measures in the route survey process is ensuring proper overhead height measurement.
Pavement Measurement with Laser Sensors
Profilometers provide high-quality measurements of pavement deformations at highway speeds. The equipment measures the longitudinal and transverse road profiles, International Roughness Index (IRI), wheel path rut depth, Ride Number (RN) and macro texture of asphalt and concrete surfaces.
Profiling Translucent Glue Beads
Laser scanners are used to verify weld joints for ample filler metal and gaps. Similarly, engineers choose laser scanners to follow pneumatic sealant or glue dispensers to verify bead presence and dimensions.
Propeller Blade Profiling
A major North American propeller manufacturer and service company selected a long-range triangulation sensor to measure the profile of its propellers and controllable tip blades during the manufacturing process. Non-contact measuring, like that afforded by laser sensors, is desirable in propeller manufacturing.
Road Profiling
Road profiling systems incorporate non-contact laser sensors to measure the distance to the road surface and accelerometers to compensate for the effects of the vehicles movement.
Rotary Kiln Profile Measurement
Global equipment providers to the cement and minerals industries use distance laser meters for diagnosing runout and shape deformation problems.
