Data sheet dithering removal filter
Description
Dithering removal filter.
Principle:
- The Fourier filtering allows modifying certain unwanted frequencies of an object by inserting a mask adapted in the Fourier plane (or focal plane of the initialimage).
- Thus, the image (or the different spatial frequencies which constitute it), is interpreted as a diffraction pattern.
These measurements thus require a collimated light source, but mostly purified: this is why the Ovio Laser Torch (ref. 204 080), ready to use and pre-set, is perfect for this type of techniques.
Results:
Influence of the slit opening (reading of the micrometric screw) on the jamming of spaced lines of different frequencies
