Print display – small pcb - dynamic interlaced composite video is digitised at 25 fps and each field is interpolated in x and y in real time to produce two non interlaced frames which are displayed on a non interlaced monitor at 75 fps. Up to four images may be stored and the dynamic display halted and portions of images displayed for comparison. Graphical information may be overlayed on the images.
Glass print inspection – hardware and software – two linescan cameras are synchronised and images of windscreens are taken at six second intervals. The images are joined to produce one 15,000 by 10,000 pixel image. The screen edges and all ink mark edges are detected. Based on the screen edges the screens are zoned and the number, sizes, and positions of the ink marks in each zone are tested against the required standards. Any errors above specified limits are highlighted on a monitor and the screen rejected.
Protein folding – high speed – two synchronised 200 MHz 10 bit ADCs digitise the outputs from two photo diodes. Analog programmable gain amplifiers condition the signals. The light is plane polarised and different wavelengths can be used. The data is collected and analysed to provide information on the dynamic mixing of proteins.
Web server – compact pcb – data is collected remotely and processed. The system is connected to an Ethernet network. It has a TCP/IP stack and a web server. It is controlled from a web browser (Internet Explorer or other browser) and results collected through Java programs.
Photon detector – solid state – images are focussed onto a ½ inch solid state detector. Photon rates may be from several hundred thousand per second down to one every few seconds. The charge generated by each photon is collected at the four corners of the detector. The charges are amplified, converted to voltages and digitised. When a photon hits the detector the position can be calculated by comparing the peak voltages from the four corners. These photon events are logged and an image is built up by integrating the photons arrivals over a time. Image resolutions of 512x512 may be readily achieved.
