What do they mean by time slits? A beam of light twice gated in time... what does this mean?
Is it something like sending pulses of light towards each other separated by some very small amount of time and observing an interference pattern of some kind?
- armchairhacker 4y agoI believe it's like a filter which briefly lets light pass through, twice, although the way they achieve this is weird. In conventional double-slit the 2 splits have different x positions, here they have different t positions. The diagram of page 3 of this helped me understand: https://arxiv.org/ftp/arxiv/papers/2206/2206.04362.pdf https://arxiv.org/ftp/arxiv/papers/2206/2206.04362.pdf.
- totetsu 4y agoSo like a rolling shutter?
- bb88 4y agoA rolling shutter doesn't cause changes in frequency of the light itself. The temporal slit appears to be causing frequency changes in the light beam. These frequency changes then interfere with each other creating a diffraction in the spectral frequency (rather than by physical distance as is with the traditional double slit experiment).
- MayeulC 4y agoIt also sounds a lot like a phased array antenna from the descriptions in this thread.
