Examples in Context

  1. Focal length measurement of spherical lens using joint Fourier transform spectrum interference technique
  2. Starting from the two types of fractional Fourier transforming systems suggested by Lohmann, the effect of lens with spherical aberration on the fractional Fourier transform were introduced and analyzed.
  3. This paper discusses the relationship between the fractional Fourier transform and the Fresnel diffraction, and presents that the optical diffraction from a spherical surface equals the scaled fractional Fourier transform. This new relationship is employed to design diffractive optical element.
  4. With the relation between system diffraction integral and the misaligned matrix element, the diffraction integral of the misaligned system was derived. Based on the structure parameters of fractional Fourier transform of single spherical refracting system, the misaligned fractional Fourier transform was also obtained.
  5. The location flexibility of output plane and the multiplicity of complicated system composed of single spherical refracting system must have potential practical value in fractional Fourier transform application and optical information processing.
