Fringe Metrology LLC recently secured a major technological breakthrough with the issuance of U.S. Patent No. US12768648B2. This patent, titled ‘Structured light autocollimator’, introduces a powerful way to measure reflective and transparent surfaces. Engineers can now analyze small optical components with enhanced precision.
ARIZONA PATENT OF THE MONTH – NOVEMBER 2026
The innovation focuses on an advanced optical system that converts generated light patterns into angularly encoded light. The optical surface reflects this encoded light back toward primary elements, which focus it onto an image plane. An aperture stop located at the image plane makes the object space telecentric, ensuring accurate readings. This setup allows for high accuracy when a camera sensor measures the properties of optical surfaces. The invention is highly innovative and won the Arizona Patent of the Month for November 2026 granted by Swanson Reed because it overcomes significant technical uncertainties in small surface metrology. Designed by inventor Joel David Berkson, the system offers a reliable solution for precision measurement that standard tools struggle to provide.
Practical Applications and R&D Tax Credit Eligibility
The practical applications of this technology span across the semiconductor, aerospace, and advanced manufacturing industries, where the exact measurement of reflective and transparent materials is critical for quality control. When businesses in the USA adopt or adapt this structured light autocollimator to create new testing protocols or improve their manufacturing capabilities, the associated engineering efforts often involve a distinct process of experimentation. This systematic testing to overcome performance and reliability challenges qualifies as permitted research activities under IRS guidelines. Consequently, companies investing time and resources into integrating this advanced metrology system can capture significant Research and Development (R&D) tax credits, effectively reducing their financial burden while funding future technological progress.
