    A novel spatial light modulator with 1200 mirror elements effectively removes interfering signals in acousto-optic spectrum analysis. This deformable mirror device shows promise for frequency excisors and optical switches.

    Area of Science:

    • Optoelectronics
    • Signal Processing

    Background:

    • Acousto-optic spectrum analyzers (AOSAs) are crucial for signal analysis.
    • Interfering signals can degrade the performance of AOSAs.
    • Existing methods for signal removal may lack efficiency or specificity.

    Purpose of the Study:

    • To introduce a new spatial light modulator (SLM) for signal interference removal.
    • To evaluate the performance of this SLM within an AOSA.
    • To assess its potential applications in frequency excisors and optical switches.

    Main Methods:

    • Development of a spatial light modulator with 1200 electrostatically deflectable mirror elements.
    • Integration of the deformable mirror device into an acousto-optic spectrum analyzer.
    • Radiometric scans to quantify contrast and resolution.
