Cool, but not that new. So what about using diffraction with infrared light? Yes, that would be cool, but we can't really see infrared (well, there is a body hack for this).

Our aim has been to obtain X-ray diffraction diagrams of oriented preparations of the flagella of algae, sperm, etc., of a standard comparable with those already obtained with bacterial flagella1 ...

Figure 1: X-ray Bragg diffraction diagram, X-ray Bragg reflectivity from a thick diamond crystal, and a colour map of averaged Bragg reflectivities for all allowed Bragg reflections and photon ...

Overview When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same ...
