As part of PolyU’s efforts to prevent the spread of the novel coronavirus, remote infrared body temperature measurement was implemented at various entrances of the university in early February 2020. This was done with the help of Dr Wallace Lai of the Department of Land Surveying and Geo-Informatics (LSGI), who converted prior work developed by Dr Steven Tsang in the Department of Building and Real Estate back in 2003 to fight SARS into feasible practice within a short period. Based on the scientific ground work done by Prof. Lung-Sang Chan and his team from the University of Hong Kong, Dr Lai elaborated on the science behind this preventive measure for the colleagues of the Facilities Management Office for their implementation.
