    A novel optical profilometry method, linearly coded profilometry (LCP), uses a sawtooth light pattern for faster surface measurement. This technique offers high accuracy and reliability, making it a promising alternative to existing methods.

    Area of Science:

    • Optical engineering
    • Metrology
    • Surface characterization

    Background:

    • Optical profilometry is crucial for 3D surface measurement.
    • Existing methods like phase-measuring profilometry can be complex and slow.
    • A need exists for faster and simpler optical measurement techniques.

    Purpose of the Study:

    • To introduce a new triangulation-based optical profilometry technique called linearly coded profilometry (LCP).
    • To develop a simpler and faster method for 3D surface profiling.
    • To demonstrate the reliability and accuracy of the proposed LCP method.

    Main Methods:

    • Utilizes a linear coding technique with a periodic sawtoothlike structured light.
    • Employs phase-shifting techniques for decoding the surface profile.
