In recent years there is an increasing demand for imaging systems with high
end specifications on image quality along with the need to extend the depth
of field. Digital cameras and imaging devices are nowadays integral parts of
communication systems such as closed-circuit television (CCTV) surveillance
systems and cell-phones, barcode readers, iris recognition devices, etc.
Typically imaging systems design targets aberration correction and image
resolution over required field of view whereas an issue of depth of image
field remains unattended. However there are a lot of imaging applications
where the extended depth of field in object and image space is strongly
required.
The main part of the seminar deals with theoretical
considerations and engineering methods for substantial increasing the depth
of field of incoherent broad spectrum imaging systems, while keeping quite
high resolution, contrast and light throughput. Results on combination of
image fusion and extension of the depth of field are presented. It is shown
that achieved extension of the field of view substantially releases
tolerances for longitudinal positioning of the object, lenses and image
sensor without a substantial reduction of the image quality and resolution.
The novel approaches presented cover theoretical considerations, computer
simulations as well as experimental results
