Abstract
Applications of digital imaging with extreme zoom
are traditionally found in astronomy and wild life
monitoring. More recently, the need for such
capabilities has extended to wide area monitoring such
as forest fires, harbors, and waterways. This paper
presents a number of sensor arrangements for the
acquisition of high magnification images. It also
describes user interfaces developed for the system's
remote control and data acquisition and processing.
Hardware and software considerations are addressed,
focusing on optical setups and image de-blurring
techniques. An image restoration algorithm tailored to
such systems is developed, where an adaptive
sharpness measure is employed as a cost function to
guide the search for an optimal point spread function
