Payload I |
High resolution imaging applications:
- high resolution aerial photography
- can generate stereo imagery, using adjacent aerial photographs
- can generate additional information, by using orthogonal polarisations
- can use a computer to subtract images taken at different times, to spot differences
- can detect the presence of something that should not be there
- can estimate the number of people in a crowd, or, the number of items in a collection
Visual imaging systems:
By way of example, we consider the Kodak KAF - 10500 CCD device. The following information is from the Kodak web site at http://wwwuk.kodak.com/ezpres/business/ccd/global/plugins/acrobat/en/datasheet/fullframe/KAF-10500LongSpec.pdf
The cover glass over the CCD also acts as an infra-red filter, as shown above, with specifications shown below.
The typical spectral performance with the cover glass in place is shown above. One can clearly see that the spectral performance of the CCD extends from 400 nm to 700 nm.
This interesting system from TX IMMERSIVE Limited ( www.tx-i.eu ) enables the viewer to look in almost any direction without the need for any mechanical movement of the system. Software and electronic hardware simply stitches together the required image from one or more of the 640 x 480 pixel imagers in the sphere. Neat. Photograph taken at DSEi 2007.
