Frequency scrambling filter.
Principle:
- Fourier filtering allows the modification of certain undesirable frequencies of an object by inserting a suitable mask in the Fourier plane (or the focusing plane of the initial image).
- Thus, the image (or the different spatial frequencies that constitute it) is interpreted as a diffraction pattern.
These measurements therefore require a collimated, but above all purified light source: this is why the Ovio Laser Torch (ref. 204 080), ready to use and pre-set, is ideal for this type of technique.
Results:
Influence of the aperture of the slit (reading on the micrometer screw) on the scrambling of lines spaced at different frequencies.
