Kyowa Sampling Moire Camera DSMC-100A-2 M1

1. Simplified remote XYZ-displacemnet measurement by using camera
This product can measure from a place away from the object to be measured. It is possible to measure even in places where it is difficult to access or install measuring equipment such as under the bridge, river bridges or overpasses, and the convenience does not decrease due to enforcement of traffic restrictions during the measurement period. In addition, we developed a new algorithm and made it possible to measure out-of-plane displacement with one camera, so it can be used in various field environments without limiting the installation location of the device.
 
* Out-of-plane displacement measurement: Measurement of displacement in the depth direction (line of sight) of the captured image. Previously, more than two cameras were needed.

2.High-speed shooting (up to 500 fps* or higher) is possible
High-speed shooting of 500 fps or more by DSP* processing inside the camera makes it possible to capture changes in the natural frequency of structures and peak values of dynamic displacement such as bridges and floor slab deflections when high-speed vehicles pass through.
 
*fps (flame per second): The number of images that can be taken per second.
*DSP (digital signal processor): A processor for digital signal processing.
 
3.Confirmation of waveform by real-time monitor during measurement
Since the displacement data during measurement can be monitored simultaneously on multiple channels, it is possible to immediately check on-site for abnormalities in recorded data and the current status of structures. Therefore, it is possible to prevent reworking of data processing and analysis, such as redoing measurement work, and perform efficient measurement.
 
4.Supports continuous measurement for 24 hours or more
The fixed point observation mode that supports long-term continuous monitoring enables long-term unattended measurement. It is also possible to measure the deformation of structures throughout the year and build a remote monitoring system in the event of a disaster.
