Laser Optical Displacement Sensor

Product Description:

Laser video extensometer refers to the processing of optical photos or videos through sub-pixel segmentation and computer algorithms to obtain the amount of displacement change and strain value between any two points.

The principle is to obtain the change of the position of the reflective strip by scanning the reflective strip with laser at high frequency in advance, and then get the displacement change and strain value between the reflective strip. The extensometer is equipped with a high speed and high accuracy data acquisition and processing system, and a communication system that can support various types of testing machines. It can be widely used in the study of mechanical properties and behavior of materials and parts. It is particularly useful for applications where the use of conventional extensometers is limited, such as non-conventional materials, confined space, harsh environment and other occasions.

(2) The original pitch of the video extensometer has no effect on the strain accuracy.

(3) The video extensometer can be set at any distance and field of view.

(4) All metal and non-metal specimens can be used.

(5) Non-contact measurement, no effect on the performance of the specimen.

(6) Wide measurement range, can be as small as microns to several meters.

(7) The whole test can be measured and tracked, and the specimen breakage does not affect the measuring device.

(8) Test results have displacement, strain, chromatogram, test curve, etc.

(9) It can be used in various environments such as high temperature, high pressure, dynamic fatigue and with radiation.

(10) Portable device, traceable testing process
