About

M. Halioua is a pioneering figure in optical metrology, best known for advancing automated phase-measuring profilometry for three-dimensional surface imaging. His seminal 1984 paper, "Automated phase-measuring profilometry of 3-D diffuse objects," has garnered nearly 1,000 citations, reflecting its foundational impact on high-resolution, non-contact surface measurement. In this work, Halioua introduced a method that extracts surface profiles by analyzing the phase distribution of a projected sinusoidal grating deformed by an object’s topography. Crucially, he employed a shearing polarization interferometer for projection and an array detector for image capture, enabling rapid, automated acquisition of diffuse object shapes. This innovation bridged classical interferometry with modern digital imaging, laying groundwork for applications in industrial inspection, biomedical imaging, and computer vision. Halioua’s contributions remain essential reading for researchers in optical engineering and 3D sensing, offering a clear, elegant solution to a longstanding challenge in profilometry.
