The sole laser scanner mainly collects sole data through the principle of laser.
The principle is as follows:
1. A low-power laser beam is projected onto the sole surface through a laser transmitter. After the beam touches the sole, it is emitted to a high-precision sensor.
2. The sensor calculates the precise distance between each point on the sole and the scanner by analyzing the change in the time difference or phase change of the laser reflection, thereby forming spatial coordinate data.
3. Then, according to the point cloud data processing of the software, the surface morphology is reconstructed to form a three-dimensional model, and key data such as arch height, foot length and foot width are calculated at the same time.
Laser measurement is a non-contact scanning method. The measured data can avoid data distortion due to pressure or friction, and will not cause physical damage to the foot. The scanning speed is fast, and it generally only takes tens of seconds to complete the measurement.
So, is laser scanning safe?
This is a question that many people are worried about.
In fact, laser scanning uses low-power lasers, with wavelengths usually between 630-680nm, and energy levels of Class or Clas2, which are non-ionizing radiation and will not cause harm to human skin and eyes, and meet human safety standards.
Moreover, laser scanning is fast, generally only 5-30 seconds, which is far below the exposure limit specified by the laser safety threshold.
Therefore, for foot laser scanning equipment, there is no need to worry about safety issues caused by laser scanning, and you can use it with confidence.
