and circular polarization. What grammarian made that decision is anyone’s guess, but that’s how things are. It isn’t hard to create a circularly polarized signal. Please see Figure 1. A circularly ...

This is called cross-polarization ... depending on the rotation of the circular polarizing filter. So try rotating the filter to change the contrast and create a range of interesting effects.

A new instrument can measure circular polarization, caused by the biosignature homochirality ... life – homochirality – from a speeding helicopter. This instrument could make the search for life on ...
