hi,

don't know if this has been posted yet: http://www.imagesensors.org/Past%20W...ens_596cm2.pdf

May as well go ULF at 17x17".

Fuji on the hunt.

do you think, this is the same technology that Largesense is using?

Probably not. There may be similarities, but the fuji contraption is an xray detector. It doesn't see visible light.

In the above mentioned document, it is stated that they use a cmos sensor that is being used in x-ray detectors. Don't know about the fuji, but there are digital x-ray detectors consisting of a combination of a light sensitive sensor plus a scintillator that converts x-ray to visible light. You can read about it here

Further reading reveals they can auto stitch the imagery.

I wish they mad a FF 6mp 6 x 6 back for the Hassy and brought it in at $2500

I suspect it's Mitchell Feinberg's custom back: http://aphotoeditor.com/2011/08/23/m...-capture-back/

Compare figure 6 in the PDF to the photo of the back in this link.

Yes it's the back he is using. But my question was, if they are using the x-ray detector's cmos too.

They might, but the question is to what extent the similarities are relevant. The largesense would have a bayer array attached to it, making the entire subassembly a custom piece. That the actual photodetector itself is a cmos array is quite likely. That it originates from DALSA is also quite likely, as they're one of the few (or perhaps the only one) in the world who manufacture image sensors at this size. There are bound to be many technical similarities, but there are nearly just as many technical similarities between the CMOS sensor in a consumer-grade Canon camera and the 8x10 sensor(s) discussed here. What does the phrase 'same technology' mean? The same fundamental physics concepts? The same manufacturing technology? Identical parts used? How similar must it be to be the 'same' to you? If you look into it deeply enough, it becomes a moot point given the structure of the semiconductor industry and the state of technology regarding cmos sensors.
