How does the discussion object spatial frequency and use it to control the imagery the quality with the shape.
Carries on simple optics image processing using the Fourier optics theory.
This experiment discusses how is the subject and object spatial frequency are, and uses it to control the imagery, shape and quality. This subject seeks a specific profile, the harmonic frequency is the same concept in the Fourier optics theory mentioned that object all has the specific intensity pattern and may transform for the relative spatial frequency distribution. In this experiment laser is shone by the thunder the object slide. Transforms the lens, the affiliation by hereafter to inspect its spatial frequency the distribution In transforms the lens in the focal-plane to present. The affiliation by holds controls in this focal-plane the light We then may control the imagery the content and the quality.
