In the next year and a half, there will be four blood moons, which is a rare phenomenon that astronomers have a name for: a tetrad. Tetrads come and go, according to NASA lunar eclipse expert Fred Espenak. Some centuries have several, and the 21st century will have eight. However, there were none between 1600 and 1900.
Thermal Imaging really canât see through walls but at Infrared New England we can do the next best thing.We use the most sensitive thermal imaging cameras available in the Infrared industry.High-resolution equipment combined with 35 years of building experience and building science background gives us the ability to âalmostâ see through walls.e use the most sensitive thermal imaging cameras available in the Infrared industry.

Public safety officers such as search and rescue personnel and firemen also use thermal imaging. Many fire departments use hand-held or helmet-mounted cameras to see through smoke to find victims, or to see âhot spotsâ in walls before a fire spreads.ue to the change in thermal characteristics of a surface caused by an adjoining wall or bulkhead, thermal imagers highlight structural details unseen by the naked eye. New applications are emerging every day in the use of thermal imaging, both in and out of the field of law enforcement.
