METHODS FOR ABERRATION CORRECTION IN HIGH NUMERICAL APERTURE OPTICAL SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027784 titled 'METHODS FOR ABERRATION CORRECTION IN HIGH NUMERICAL APERTURE OPTICAL SYSTEMS

Simplified Explanation

The abstract describes a wavelength dispersive optical system that includes an optical input for projecting an input optical beam with multiple wavelength components and an optical output for receiving one or more output optical beams. The system also includes a diffractive optical element (DOE) with a substrate and an array of physical diffraction elements. The diffraction elements have a predefined spacing and/or curvature across the DOE and are collectively adapted to spatially separate the wavelength components, correct for optical aberrations, and apply wavelength-dependent optical focusing. The system further includes an optical focusing element that complements the DOE to modify the wavelength-dependent optical focusing.

  • The system is a wavelength dispersive optical system.
  • It includes an optical input for projecting an input optical beam with multiple wavelength components.
  • It includes an optical output for receiving one or more output optical beams.
  • The system includes a diffractive optical element (DOE) with a substrate and an array of physical diffraction elements.
  • The diffraction elements have a predefined spacing and/or curvature across the DOE.
  • The diffraction elements spatially separate the wavelength components within the input optical beam to form the output optical beams.
  • The diffraction elements impose predefined phase changes to correct for optical aberrations in the input optical beam.
  • The diffraction elements also impose predefined phase changes to apply wavelength-dependent optical focusing to some of the wavelength components.
  • The system includes an optical focusing element that complements the DOE.
  • The optical focusing element modifies the wavelength-dependent optical focusing of the wavelength components by the DOE.

Potential applications of this technology:

  • Spectroscopy: The system can be used for wavelength dispersion and separation of different wavelength components, making it useful in spectroscopic analysis.
  • Optical communications: The system can be used for wavelength multiplexing and demultiplexing in optical communication systems, allowing for efficient transmission of multiple signals over a single optical fiber.

Problems solved by this technology:

  • Optical aberrations: The system corrects for optical aberrations in the input optical beam, improving the quality and accuracy of the output optical beams.
  • Wavelength separation: The system spatially separates the individual wavelength components within the input optical beam, allowing for precise control and manipulation of each component.

Benefits of this technology:

  • Improved optical performance: The system's ability to correct for optical aberrations and apply wavelength-dependent optical focusing improves the overall performance and accuracy of optical systems.
  • Compact and efficient design: The use of a diffractive optical element allows for a compact and efficient design, reducing the size and complexity of optical systems.
  • Versatile applications: The system can be applied in various fields such as spectroscopy, optical communications, and other areas where wavelength dispersion and manipulation are required.
