Hi guys,
I've been thinking: If you vibrated a CCD chip randomly by a small amount (say, 0.5 of its pixel) in both the X and Y direction, could this be used to add positional noise to the chip, then captured full frames randomly, shouldn't it be possible through some clever math to achieve some spacial equivalent of what you get with dithering for an ADC - essentially gain a higher spacial resolution?
If you just have a stationary CCD chip you can sample all you want, you will still be looking at the same points. But with some small vibration device (seeing as you have point sizes of several um these days, a MEMS vibration thingie on the PCB with the CCD chip should do it) you should be able to actually shift the point of view for each pixel, adding some dithering.
Thanks,
David
