    Summary

    Hadamard transformation enhances photoacoustic imaging by reducing sample power density and improving signal-to-noise ratio (SNR) through multiplexing. Its compatibility with other multiplex techniques is also explored.

    Area of Science:

    • Optics and Imaging
    • Biomedical Engineering

    Background:

    • Photoacoustic imaging (PAI) offers non-ionizing contrast for biological tissues.
    • High power density can be a limitation in PAI, potentially causing sample damage.
    • Improving signal-to-noise ratio (SNR) is crucial for enhanced PAI resolution and sensitivity.

    Purpose of the Study:

    • To apply Hadamard transformation principles to photoacoustic imaging.
    • To investigate the benefits of Hadamard transformation for PAI, specifically power reduction and SNR improvement.
    • To assess the compatibility of Hadamard transformation with other multiplex transform techniques in PAI.

    Main Methods:

    • Implementation of Hadamard transformation principles within the photoacoustic imaging framework.
    • Analysis of power density distribution at the sample.
    • Evaluation of SNR improvements attributed to the multiplexing advantage of Hadamard encoding.

    Main Results:

    • Demonstrated reduction in power density delivered to the sample.
    • Significant improvement in SNR achieved through Hadamard-based multiplexing.
    • Discussion on the synergistic potential of Hadamard transformation with other multiplexing strategies.

    Conclusions:

    • Hadamard transformation is a viable technique for enhancing photoacoustic imaging.
    • The method offers dual benefits of reduced sample power and improved SNR.
    • Compatibility with other multiplex techniques suggests broader applicability in advanced PAI systems.
