Interline CCD Images in TDI Scanning Mode

The existing TDI techniques have been limited to line-scan like imagers, but it is possible to use the ordinary area scan interline transfer CCD imaging devices in TDI scanning mode, which allows the user to obtain a high resolution area-scan image with very high sensitivity from any conventional interline transfer CCD imager.

Wide Dynamic Range Imaging

One way to increase dynamic range is to take several images at different exposures and then combine them to achieve a net higher dynamic range. This approach works well, if there is no motion in the scene, and there are extended periods of time available to process the image, but dynamic imaging applications involve motion of either the camera or the object being observed and taking multiple sequential exposures causes image blur. The Cheetah camera, however, has been optimized for high speed surveillance and tracking applications by employing a proprietary method to extend the sensors dynamic range using multiple-slope exposures within a single frame time eliminating motion blurring effects.

UAV - Demand Driving Innovation in Surveillance Technologies

The rapidly growing demand for unmanned vehicles for surveillance is likewise driving demand for-and innovation in-sophisticated persistent-surveillance sensors. Satellites, unmanned aircraft, unmanned surface vessels, unmanned land vehices, and even tethered aerostats are bringing the latest surveillance sensor technologies to bear. Sensor payloads involve electro-optical sensors, acoustic sensors, motion sensors, and combinations of all the above bring military situational awareness to levels never seen before.

Vision Systems – Smart Camera or PC-based

The question often comes up as to what is the most appropriate approach to take in implementing a machine vision system - using a Smart Camera or using some sort of PC-based approach. There is no question that as the microprocessor, DSPs and FPGAs are getting faster and, therefore, more capable, Smart Cameras are getting smarter. Hence, they are a challenge to more ''traditional'' approaches to machine vision. Significantly, however, ''traditional'' approaches are also taking advantage of the advances and so, too, are faster and smarter.
