About

Laurence G. Hassebrook is a leading figure in the field of 3D optical metrology and structured light imaging, with a career dedicated to pushing the boundaries of non-contact surface scanning. His primary research areas encompass high-resolution 3D surface scanning, real-time data acquisition, and human-computer interaction using structured light projection. Hassebrook’s most notable contribution is his seminal work on multi-frequency phase measuring profilometry (PMP), which enables very high-resolution 3D scanning across scales ranging from millimeters to meters. His 2005 paper on this technique, with 49 citations, remains a foundational reference in the field. He also pioneered methods for real-time 3D data acquisition using single-pattern projection, significantly reducing the complexity of traditional multi-pattern approaches. A particularly innovative application of his work is in augmented-reality interfaces for space environments, where his composite pattern structured light system allows astronauts to control computers through 3D hand gestures while wearing bulky space suits. Hassebrook’s research has had lasting impact on both industrial metrology and interactive technology, demonstrating how precise optical engineering can solve real-world challenges in extreme environments.
