Laser scanner, such as the Z-Trak LP1 Laser Profiler, are laser displacement sensors that measure both position and height data along z axis of a laser line, covering angles over a wide measurement range. These high-accuracy, high-resolution 3D laser scanner offer numerous benefits at a cost-effective total cost of ownership. They can be used for:
- Two-dimensional and three-dimensional measurements
- Utilizing a single sensor system with advanced optical sensor systems, two sensors including a cylindrical lens.
- Height difference, width and angle
Versatility of Laser Scanners in Industries
Laser scanners can optimize exposure time for better accuracy and handle object widths ranging from 8.5 mm to 1520 mm, and heights from 10 mm to 1000 mm, using reflected light to measure and adjust the distance. Laser scanner are well-suited for:
- In-line measurement
- Guidance applications
In-Depth Look at Laser Profiler Technology
Laser profiler technology is a method of measuring displacements and surface heights utilizing high accuracy sensors and laser line triangulation principles. It enables the capture of precise distance measurements in a variety of applications, revolutionizing the way we assess and analyze surfaces.
Laser Triangulation Method
Laser triangulation is a machine vision technique used to capture three-dimensional measurements. It works by projecting a laser beam onto a target surface and calculating the distance based on the angle of the reflected beam. This method is regularly employed in measurement technology, as it enables precise distance measurements and is highly resistant to interference from external light.
Some key features of laser trilateration include :
Precise distance measurements
Ability to measure almost any type of opaque surface, regardless of its finish or color
Resistance to interference from external light
Integration Time Optimization
Integration time optimization is the process of determining the optimal duration for integrating signals from sensors in a measurement or imaging system, aiming to capture enough signal information while minimizing noise or artifacts. Optimizing the sensor integration time can improve the quality and accuracy of the measurements or images, providing more reliable data.
When it comes to laser profilers, adjusting the exposure time through integration time optimization ensures the accuracy profile data, and reliability of the data. This process not only enhances the precision of laser profiler measurements but also reduces noise and artifacts, leading to improved accuracy and consistency of data.
Surface Profile Detection
Surface profile detection describes the process of measuring and analyzing the topography or roughness of a surface. It involves determining the height variations and characteristics of the surface, including peaks, valleys, and texture. Surface profiles can be measured and analyzed using a variety of devices, including stylus devices, laser scanner, and depth micrometers.
Surface profile measurement and detection is a vital tool in numerous industries, such as manufacturing, quality control, and coatings inspection, as it assists the manufacturer in evaluating and measuring the surface’s performance, adhesion, and overall quality. Laser profilers are capable of detecting surface profiles, measuring and assessing different surface features, and defects including bumps, dents, and scratches, ensuring that surfaces meet the required standards.
Applications of Laser Profilers in Different Industries
Laser profilers have a wide range of applications across different industries, including gap measurement and inspection, material flatness measurement and inspection, and pipe size measurement and inspection. The AP820 series, for example, is suitable for a wide range of non-contact measurements and inspections, such as surface profile measurements, dimensions, deformations, flatness, gaps, volume, height, and thickness.
Gap measurement pertains to the process of measuring the space between two objects or surfaces. It is often utilized in various industries to guarantee the correct fit, alignment, or clearance between components.
Laser profilers offer significant advantages for gap measurement, including:
- High accuracy
- High resolution
- High speed
- Ability to measure a broad range of materials and surfaces
Flatness measurement is a method utilized to assess the shape of a surface and verify that all points on that surface are situated in the same plane. Traditional methods for flatness profile measurement may include using tools with measuring ranges such as a height gauge or a surface plate.
However, laser scan offer enhanced accuracy, faster profile measurement over times, and the capacity to measure more complex profiles and shapes, which are all advantages over traditional methods of flatness profile measurement used.
Pipe Size Measurement
Pipe sizes measurement is the process of determining the size, width or dimensions of a pipe. This is of critical importance in the oil and gas industry, as it guarantees that the pipes are capable of withstanding the pressure of the oil and gas being transported. The most prevalent technique for determining pipe, width or size is to employ a soft tape measure to measure the external circumference and width of the pipe and divide the measurement by pi (approximately 3.14159).
Laser scan provide the following advantages when measuring pipe thickness and size:
- Greater accuracy and precision compared to traditional methods
- Ability to measure pipe size in challenging locations, such as offshore drilling operations
- Significantly reduced measurement time compared to traditional methods
Choosing the Right Laser Profiler for Your Needs
Selecting the appropriate laser profiler for your needs involves considering several factors. These include the desired resolution, accuracy, and compatibility with existing systems.
Consider the specific requirements of your target application and the types of measurements you need to perform. Also, evaluate the compatibility of the laser profiler solution with the software solutions you are using. The Z-Trak LP1 Laser Profiler, for example, is compatible with both Teledyne DALSA computer vision software and off-the-shelf 3rd party 3D image processing packages.
A careful assessment of your specific requirements and the capabilities of various laser profilers guarantees an investment in the right tool for your application and operation. This will ultimately lead to more accurate and efficient measurements, improving the overall quality service life and performance of your material and processes.
