Miniaturization of the HABLAN system, which performs multi-spectral and multi-angular remote sensing of nocturnal artificial light — A number of studies have established statistical links between artificial light at night (LAN) and the risk associated with certain diseases such as hormone-dependent cancers (HDCs). Recent studies with colour images taken by astronauts on the International Space Station show that the blue component of light is strongly linked to the occurrence of HDCs. To better characterize the level of LAN as well as its blue component, it is essential to have multispectral and multi-angular remote sensing techniques for LAN.

The calculations made by the model developed during this project will ultimately make it possible to deduce the risks associated with LAN to the health of Canadians and thus possibly modify usual night lighting practices to minimize these risks. The HABLAN project also provides an opportunity to increase the diversity of space-based science critical to clean growth and monitoring the health of the planet and, more specifically, that of Canadians. LAN remote sensing makes it po
