This study introduces a new wavelet transform based on symplectic and translation parameters. This novel approach offers well-behaved properties and connects to quantum optical Fresnel transforms.

Area of Science:

  • Quantum mechanics
  • Wavelet analysis
  • Signal processing

Background:

  • Traditional wavelet transforms utilize dilated and translated wavelets.
  • Existing methods have limitations in certain advanced applications.

Purpose of the Study:

  • To introduce a novel wavelet family generated through symplectic transformation and translation.
  • To explore the properties and applications of this new transform.

Main Methods:

  • A new wavelet family, psi(*)(r,s)(z-kappa), is defined using symplectic parameters (r,s) and translation parameter (kappa).
  • The corresponding wavelet transformation W(psi)f(r,s;kappa) is defined via an integral formula.
  • The parameters satisfy the condition |s|(2)-|r|(2)=1.
