We introduce code division multiplexing for superresolution imaging, enhancing field of view without sacrificing resolution. This novel approach offers superior capabilities compared to traditional frequency division multiplexing methods.

Area of Science:

  • Optics and Photonics
  • Signal Processing
  • Imaging Science

Background:

  • Traditional superresolution techniques often compromise field of view when increasing resolution.
  • Existing methods utilize frequency division multiplexing (FDM) principles to expand spectral range.
  • There is a need for advanced multiplexing strategies in superresolution imaging.

Purpose of the Study:

  • To propose and analyze code division multiplexing (CDM) as a novel approach for superresolution imaging.
  • To overcome the trade-off between resolution and field of view in superresolution.
  • To demonstrate the superior capabilities of CDM over traditional methods.

Main Methods:

  • Development of a unique optical setup to generate an incoherent cosine transform of an image.

  • Theoretical analysis of the proposed CDM system for superresolution.
  • Experimental validation and comparison of theoretical predictions with empirical results.

    • Main Results:

    • Code division multiplexing enables superresolution imaging with an enhanced field of view.
    • The proposed system demonstrates superior performance compared to conventional multiplexing techniques.
    • Theoretical analysis aligns well with experimental findings, validating the approach.

    Conclusions:

    • Code division multiplexing is a viable and effective strategy for advancing superresolution imaging.
    • The developed incoherent cosine transform setup facilitates CDM for improved imaging capabilities.
    • This work opens new avenues for high-resolution, wide-field-of-view imaging applications.
