A problem in modular shipbuilding is the lack of a reliable, low-cost method of obtaining and utilizing dimensional control in 3D. Photogrammetry has been successfully used as a tool for this application, but because of the large number of systematic errors associated with film-based cameras, only very large shipyards are using it. Recently, developments in Charge Coupled Device (CCD) imaging arrays for cameras have allowed some success in applying photogrammetric techniques dimensional control Mainstream photogrammetric software and hardware configurations have been expensive and complicated. Digital camera systems and computers were purchased and programmed to tie existing inexpensive software packages with Geometric Dilution of Control (GDOP) error propagation analysis, originally designed for topographic mapping, into a tool for production shipyard fabrication dimensional control.

An ultra-high-speed and high-accuracy charge-coupled device (CCD) laser displacement sensor is used to track and measure the ultrasonic vibration in real time. A series of Matlab programs are developed to filter noise from original data. The ultrasonic vibration frequency and period are evaluated and the ultrasonic amplitude is measured within accuracy ±0.1 μm. Effect of the ultrasonic power on the ultrasonic amplitude is also studied.

A new method to rapidly produce and screen biodegradable polymer- and xerogel-based formulations is described. The approach is based on a high-speed pin printer and imaging with an epi-fluorescence microscope/charge-coupled device detector. By using this approach we can produce and screen over 600 formulations/h and rapidly identify lead formulations and/or compositions that are the most useful for the development of biodegradable devices or (bio)sensors.

The present work aims to investigate the interaction between a plasma jet and targets with different physical properties. Electrical, morphological and fluid-dynamic characterizations were performed on a plasma jet impinging on metal, dielectric and liquid substrates by means of Intensified Charge-Coupled Device (ICCD) and high-speed Schlieren imaging techniques. The results highlight how the light emission of the discharge, its time behavior and morphology, and the plasma-induced turbulence in the flow are affected by the nature of the target. Surprisingly, the liquid target induces the formation of turbulent fronts in the gas flow similar to the metal target, although the dissipated power in the former case is lower than in the latter. On the other hand, the propagation velocity of the turbulent front is independent of the target nature and it is affected only by the working gas flow rate.

The electron microscope is becoming a link in a highly sophisticated data processing system. The acquisition of image data supplied as a spatial distribution of current density requires a position sensitive electron detector which converts the current into digital information to be processed by image storages and computers to retrieve the information in which the user is interested. The ultimate goal of this interface is a lossless conversion with respect to both the number of pixels and the detection quantum efficiency (DQE) as well as high speed, minimum distortion, and linearity. I shall try to outline the present state of image read-out using both the conventional photoplate with spatial digitizing equipment and conventional TV sets. Subsequently it will be discussed how the future CCD technology (charge coupled device) may overcome some restrictions of present solutions.Every spatial recording device combines a conversion with a storage function in order to build up a signal-to-noise ratio (SNR) sufficient for detection. The following characteristics describe their performance:
