In this case, camera can be in a rigid fixture, it won't move. The xy table would have a very smooth movement, and after it stops the trigger can be delayed the proper interval.

What exactly is "this case"? How is it immune to vibration found in strident scientific structures? The fundamental issue is not shutter vibration or any fixture construction; it is about the very ground upon which the instrument stands. Or are you just relying on impressionistic metrics?Originally Posted by Pere Casals
It is based in the DSLR shots I took while projecting the 1951 slide on the sensor
No problem with vibrations...
Again, Jac is right. There's a definite difference from having a structure setting on a concrete slab floor versus a standard wooden over joist structure. Tether. Max view. Walk around.... Alignment and focus are also critical, as is uniformity of sharpness across the entire field, and there's more, of course.

It's these factors that really define the optical limitations in most scanners - & why most high end scanners are heavy bits of kit built like machine tools. The sensor & optics are relatively the cheaper parts compared to the rest of the engineering that went into them.
Ok, but the camera won't move with a suitable fixture, and the xy table will be pretty steady 2 seconds after steppers stop.
Anyway it would be about delaying the trigger time enough, IMHO.
I've taken high dpi shots yet... sure that a fine mechanics is required, but IMHO that would not be difficult.
I think this has already more or less been established, but you guys do realize you are essentially designing film scanner backwards?
