The XTOP3D non-contact deformation measurement system is used to assess the service life of concrete. Reinforced concrete is a common construction material at building sites, but how much do you know about it? What are its primary components, and what is its typical service life? Like any material, it has a finite lifespan; it does not possess the infinite longevity that people might hope for.

The XTOP3D non-contact full-field strain measurement system facilitates the research and development of composite materials. Composite materials have become an integral part of our daily lives and industrial production; they are ubiquitous, ranging from household furniture to aircraft and rockets, and the majority of modern, high-strength materials fall into this category.

XTOP3D employs Digital Image Correlation (DIC) technology to measure the performance of rubber sealing materials used for tunnel waterproofing. Tunnel waterproofing is closely linked to public safety; water leakage incidents serve as a wake-up call for the tunnel engineering sector, underscoring the critical need to prioritize research into waterproofing technologies and material performance.

Step 1—Preparation for non-contact 3D strain measurement The XTOP3D XTDIC non-contact full-field strain measurement system is flexible and easy to use. Position the measurement head at the test site based on the specimen dimensions and adjust the setup to the appropriate measurement range.

The XTOP3D XTDIC speckle strain measurement system integrates Digital Image Correlation (DIC) technology with binocular stereo vision. Utilizing two high-speed cameras, it captures real-time speckle images of the test specimen across various stages of deformation, enabling the measurement of 3D coordinates, displacement fields, and strain fields on the object's surface. It is the first 3D optical strain measurement system in China to feature independently developed core algorithms and proprietary intellectual property, achieving a technical standard comparable to the best internationally.

3D scanners—commonly referred to in the industry simply as "3D scanners"—utilize 3D scanning technology in automotive styling design and exterior inspection, significantly shortening the time required for styling development. Furthermore, as new devices and precision components are increasingly adopted, the importance of accurately measuring these parts has become ever more prominent. Against this backdrop, the following section introduces the 3D scanning technologies and measurement solutions that 3D scanners provide for automotive design and product manufacturing.

3D profile scanners are primarily used for the 3D scanning and quality inspection of precision components. Capable of achieving an accuracy of up to 0.003 mm, they can measure dimensional deviations and detect issues such as collisions or defects—for instance, identifying missing functional protrusions on cast parts like gears, quantifying the deviation, and providing timely feedback for adjustments.

Both white-light and blue-light 3D scanners are structured-light systems that operate by projecting a light pattern onto the surface of the object being measured. The key difference is that blue light offers superior resistance to interference compared to white light; it effectively filters out ambient light, thereby enhancing scan quality and efficiency. Additionally, blue light utilizes a cold LED light source, which lowers the scanner's operating temperature and indirectly extends its service life.

Amid the pandemic, "Made in China" has frequently been a topic of discussion. my country’s manufacturing prowess extends beyond simple production; the country is growing increasingly strong in complex manufacturing and across the full spectrum of manufacturing sectors. Its vast hinterland allows for the relocation of manufacturing activities within the country, thereby extending the industry's lifecycle. However, my country's manufacturing sector faces numerous internal challenges. We still lack sufficient fundamental innovation capabilities, particularly regarding core technologies and fields such as chemistry, physics, and materials science. While we excel in incremental or simpler forms of innovation, we remain relatively weak in complex innovation.

The XTOP3D DIC grid-based strain analysis system is applied to mechanical property tests of concrete—specifically tensile and compression tests, which are the most common procedures for evaluating the fundamental mechanical properties of construction materials. The tensile and compressive strengths of construction materials depend on their service conditions, which in turn are determined by the materials' inherent structural properties.
