Conventional vibration measurement primarily relies on point sensors, making it challenging to determine the distribution of vibrations, often requiring the movement of sensors for repeated experiments or scans. 【Solving the following issues related to vibrations】 ■ The equipment or devices in use are vibrating, and it's unclear how to address this. ■ It's unclear how the vibrations causing disturbances to neighbors are being transmitted. ■ The vibration phenomenon has changed due to the attachment of an accelerometer to the vibrating object. I want to measure it non-contact. ■ I am using accelerometers and laser displacement sensors for vibration measurement, but can only measure at one point. ■ I am investigating distributions using laser Doppler vibrometers, but synchronization at each point for scanning is not achieved, preventing the measurement of transient phenomena. ■ I am conducting repeated experiments to obtain distributions, but there is a lack of reproducibility and reliability. ■ Vibration measurement requires a significant amount of labor. I want to measure vibration distributions easily, inexpensively, and in a short time. ■ The analysis results of vibrations are difficult to understand and need to be visualized. *For more details, please download the PDF or feel free to contact us.

Many structures built during the period of rapid economic growth are approaching the end of their lifespan. In particular, to ensure the safety of infrastructure such as bridges and buildings, it is necessary to evaluate their integrity. One important method for confirming their integrity is to examine the shape and deformation of the structures. Additionally, it is essential to verify the strength of newly developed structures with actual models. Representative methods for examining the shape and deformation of structures include the "Image Correlation Method," "Grid Method," "Moire Method," and particularly the newer "Sampling Moire Method." [Features] - Image Correlation Method: Randomly capture images and find patterns with the same features after deformation to investigate displacement. - Grid Method: Capture images of a regularly spaced grid pattern and examine the phase of the grid to determine displacement. - Moire Method: Overlay grids before and after deformation to investigate displacement through the resulting moire fringes. - Sampling Moire Method: Investigate displacement by capturing only the grid after deformation. *For more details, please refer to the PDF document or feel free to contact us.
