About

Vikas Gupta has pioneered accessible optical metrology, with his most impactful work centering on hand-guided qualitative deflectometry using mobile devices. His 2020 paper, which has garnered 22 citations, introduces a groundbreaking system that leverages a smartphone’s screen and front-facing camera to perform three-dimensional surface measurements. Unlike conventional mobile deflectometry systems, Gupta’s method captures surfaces with large normal variation and a wide field of view, making high-precision optical inspection portable and user-friendly. This innovation bridges the gap between laboratory-grade measurement tools and everyday technology, enabling applications in quality control, augmented reality, and consumer-grade 3D scanning. By transforming a common mobile device into a powerful deflectometric sensor, Gupta has democratized surface metrology, allowing researchers and engineers to conduct accurate, real-time shape analysis without specialized equipment. His work stands out for its practical ingenuity, reducing cost and complexity while expanding measurement capabilities. Vikas Gupta’s contributions exemplify how clever integration of existing hardware can open new frontiers in optical engineering, inspiring further research into mobile-based sensing and non-contact inspection methods.
