Reviving History: Western University's Breakthrough in Imaging Technology

Professor T.K. Sham and his team have developed a groundbreaking synchrotron imaging technique that breathes new life into tarnished daguerreotypes, the earliest form of photographs. Their research, conducted at the Canadian Light Source and detailed in the Journal of Cultural Heritage, successfully retrieves images from these antiques, regardless of surface damage from corrosion or past cleaning attempts.
Daguerreotypes are subject to degradation, which can completely obscure the image.

This versatile technique extends beyond historical artifacts, offering new methods to study fossils and prevent corrosion in modern materials. By examining the chemical composition and distribution of corrosion on metals, the research provides insights into how to protect these materials from deteriorating.

Professor Sham's work not only helps preserve cultural heritage but also enhances our understanding of material sciences, showcasing the broad potential of synchrotron imaging in scientific research and conservation.
