    A new data-back-fiducial marking system uses LED illumination to add exact binary code data to existing cameras. This inexpensive system precisely aligns holes in the focal plane pressure plate for film marking.

    Area of Science:

    • Optics
    • Imaging Technology
    • Data Recording

    Background:

    • Accurate data recording in photography is crucial for various applications.
    • Existing methods for adding data to film can be complex or costly.

    Purpose of the Study:

    • To develop a simple, inexpensive, and exact system for binary code data-back-fiducial marking.
    • To enable the integration of this system into existing camera hardware.

    Main Methods:

    • Utilizing LED illumination directed through precisely aligned holes.
    • Implementing the system via the focal plane pressure plate of a camera.
    • Employing a binary code for data encoding.

    Main Results:

    • Demonstrated a functional data-back-fiducial marking system.
