  1. 10:00 Spectral interferometry is like not a new thing though… it’s a common way to characterize a pulse with itself, and precisely measure delay. You have to remember that a pulse is a superposition of waves with much larger extent. Also, I read the paper and they say nothing about all this relativity stuff. It’s literally just that the indium tin oxide has a faster response than expected, and the Doppler shift comes from the phase of the complex reflection coefficient of the film being modulated by the pulse
