We geometrically represent the optical transfer function (OTF) of incoherent imaging systems. Wavefront coding uses a generalized Cornu spiral for enhanced depth of field and analytical OTF parameter quantification.

Area of Science:

  • Optical Engineering
  • Image Science

Background:

  • The optical transfer function (OTF) characterizes imaging system performance.
  • Understanding OTF behavior is crucial for optimizing image quality and depth of field.

Purpose of the Study:

  • To develop a geometrical representation of the OTF for incoherent imaging systems.
  • To elucidate the role of wavefront coding in enhancing depth of field through OTF analysis.

Main Methods:

  • Mapping the OTF into a geometrical representation.
  • Utilizing a generalized Cornu spiral to model the OTF of defocused systems.
  • Analyzing salient OTF parameters such as depth of focus, nulls, and modulation.

Main Results:

  • The OTF of defocused traditional and wavefront-coded systems can be represented as a generalized Cornu spiral.
