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.

The housing will usually have a plastic window through which the infrared energy can enter. Despite often being only translucent to visible light, infrared energy is able to reach the sensor through the window because the plastic used is transparent to infrared radiation.
