Principle Principle

When a laser passes through a small aperture or encounters a tiny obstacle, it deviates from its straight path, creating a diffraction pattern. This pattern results in alternating light and dark bands on the CCD image sensor. By analyzing the spatial distribution of these bands, the size of the measured object can be calculated accurately.

Fraunhofer diffraction principle







 
     When a laser passes through a certain-sized gap or small obstacle, it will deviate from its straight-line propagation, causing a diffraction phenomenon. This results in alternating light and dark stripes on the CCD image sensor. By analyzing the spatial distribution of these stripes, the size of the measured object can be calculated.
