High-Speed Focus Inspection System Using a Position-Sensitive Detector
Precise and rapid focus detection is an essential operation in several manufacturing processes employing high-intensity lasers. However, the detection resolution of existing methods is notably low. This paper proposes a technique that provides a rapid-response, high-precision, and high-resolution focus inspection system on the basis of geometrical optics and advanced optical instruments. An ult...
متن کاملGamma Ray Imaging of Small Animals Using Position-Sensitive Photomultiplier Tubes
This thesis is an interdisciplinary investigation of small animals consisting of two parts. First, a comparison of NaI(Tl) and CsI(Tl) pixilated scintillating crystals will be presented based on results of resolution tests performed using 5 " diameter Hamamatsu 5800 PSPMTs. Second, application of the gamma ray detectors will be assessed using a biological model. The biological model chosen to a...
متن کاملA Proposed Wattmeter Using Multielectrode Tubes
FrOR direct measurement of small amounts of power, or for measurement of power over a wide range of frequencies, dynamometer wattmeters are unsatisfactory, and vacuum tube wattmeters are often resorted to. Hitherto vacuum tube wattmeters have depended for their operation on the use of tubes having a square-law characteristic, connected in a push-pull circuit so as to avoid indications caused by...
متن کاملPerformance improvement of small gamma camera using NaI(Tl) plate and position sensitive photo-multiplier tubes.
The purpose of this study was to improve the performance of a small gamma camera, utilizing a NaI(Tl) plate and a 5" position sensitive PMT. We attempted to build a NaI(Tl) plate crystal system which retained all its advantages, while at the same time integrating some of the advantages inherent in an array-type scintillation crystal system. Flood images were obtained with a lead hole mask, and ...
متن کاملOPTIMA: A Photon Counting High-Speed Photometer
OPTIMA is a small, versatile high-speed photometer which is primarily intended for time resolved observations of young high energy pulsars at optical wavelengths. The detector system consists of eight fiber fed photon counters based on avalanche photodiodes, a GPS timing receiver, an integrating CCD camera to ensure the correct pointing of the telescope and a computerized control unit. Since Ja...
