DALSA Announces 140MP Custom Designed CCD

Marketwire: DALSA announce that it has designed a custom 140 megapixel CCD powering a new generation of Intergraph's Z/I Imaging Digital Mapping Camera. This new sensor has been designed exclusively for Intergraph and is not available to other aerial camera vendors. The 140MP CCD has 12240H x 11418V pixel format.

  1. how much time needed to read one frame out ??

  2. The PR says "fast CCD readout technology provides an extreme high frame rate". I would love to see the numbers instead.

  3. all is relative... numbers?

  4. Is this done by Dick Bredthauer ? He holds the title for largest CCD yet, thats in public domain.

  5. I agree with the blog host on wanting to see numbers. It's much more interesting to me as an engineer to be able to do at least some rough calculations myself rather than having to take the marketing claims at face value.

  6. Of course, I suppose most of the articles and news releases that become available simply aren't targeted at engineers.

  7. Dear CDM,

    You are right, engineer has no decision right. So these annoncements target only deciders .... :(

  8. No I did not design this CCD. The new Dalsa chip is now the highest resolution CCD. It has a smaller pixel ~7 microns vs our 9 micron pixel, but ours (STA1600) 10560H x 10560V is a larger area. The Dalsa chip uses a Vertical Overload Drain which is necessary for high brightness scenes. Ours uses thick bulk silicon for long wavelength sensitivity in astronomical applications. Both devices are fabricated at Dalsa Semiconductor in Bromont, Canada.

  9. Dick, what is the readout rate (per channel & number of channels) if you know?

  10. Unbelievable Dick,
    The new record holder is still is only 85mm along one edge. I wonder if the world realizes you were doing this in the early '90s while the kids were playing with megapixel toys??? bobwan (from the dark side now)
