    Main Results:

    • Derived the probability of error in the presence of speckle noise.
    • Demonstrated a sharp deterioration in system performance as signal-to-noise ratio increases with speckle.
    • Identified the matched-filter-envelope squarer as the receiver device.

    Conclusions:

    • Speckle noise severely degrades binary image detection performance.
    • System reliability in information storage is compromised by speckle, especially at higher signal-to-noise ratios.
    • Further research may explore noise mitigation techniques.
