Does a foot scanner produce radiation? How does it work?

Foot scanners generally do not emit radiation. They mainly rely on optical or laser technology for measurement without emitting ionizing radiation (such as X-rays or gamma rays).

Main types of foot scanners and their working principles

✅ Optical scanning (3D foot scanner)

Principle: Use structured light or laser ranging to capture the shape of the foot through multiple cameras to generate a 3D model.

Features:

✔ No radiation, harmless to the human body.

✔ Accurately measure arch height, foot length, foot width and other data.

✔ Commonly used for corrective insole customization, footwear design, and foot health analysis.

✅ Laser scanning (laser foot measuring instrument)

Principle: Use low-power laser ranging technology to accurately measure the surface contour of the foot and generate a 3D foot shape.

Features:

✔ The laser intensity is low and will not cause harm to the human body.

✔ High accuracy, suitable for foot orthotics and footwear design.

Foot Scanner vs. X-ray Foot Examination

🚫 X-ray examination (X-ray) is used to view bone structure, has ionizing radiation, and is not suitable for daily scanning.

✅ Foot scanner (optical, laser) is only used for appearance measurement, has no radiation, and can be used for a long time.

Foot scanners are safe, have no radiation, and can be used with confidence. X-ray examinations are only required if bone problems such as fractures or joint abnormalities need to be detected, while general foot health assessments, corrective insole customization or sports gait analysis can be met using optical, pressure sensing or laser scanning.
