Looking at the thumbnail, I did think it was a Sunset

As I understand it, instead of recording millions of pixels at a time it records only one pixel at a time.
I can see several advantages to this (potentially anyway):
- with only one pixel there would be no noise from neighboring sensor sites.
- that one sensor site could be huge by todays standards.
- the pixels that matter the most get the most time.
- individual exposure settings for each pixel.
- by varying the mirror location, the focus could be adjusted for each pixel of the image.
- ultimately cheaper and easier to build. At first look it would take a lot of very small mirrors, but this isn't the case. If each mirror can move to reflect a different 'pixel' of the image only a few are needed; just enough to make sure one was available to be recorded from while the others moved to their new locations.
- feedback on the image could be generated as the imges is being created, adjusting the process as the image needs become more apparent. This works in conjunction with choosing which pixel to expose next, exposure and focus settings.
The main disadvantage I see is the same for all serial devices -- they have to be fast, very fast. But the application is greatly simplified so faster is easier to achieve.
Of course, I could not understand it at all. :P

| Looks interesting. Theoretically unlimited resolution, as there is no fixed array of pixels. It's only limited by the speed it can stream data. |
