    A computer-generated variable density spatial filter (VDSF) significantly improves rotating mirror image position sensors (IPS). This enhancement overcomes cross-coupling and nonlinear effects in high-resolution laser trackers, boosting overall performance.

    Area of Science:

    • Optics and Photonics
    • Optical Engineering
    • Sensor Technology

    Background:

    • Laser sources offer narrow beamwidth advantages for short-range, high angular resolution tracking applications.
    • Image Position Sensors (IPS) are crucial for determining the angle of arrival of optical radiation from targets.
    • Rotating mirror IPS can suffer from cross-coupling and nonlinear effects with large image displacements.

    Purpose of the Study:

    • To analyze and mitigate performance limitations in rotating mirror Image Position Sensors (IPS).
    • To investigate the impact of image displacement on IPS accuracy.
    • To enhance the performance of laser-based angular resolution trackers.

    Main Methods:

    • Analytical and empirical investigation of rotating mirror IPS performance.
