Definition von foto multiplikatör im Türkisch Englisch wörterbuch

photomultiplier

A device, normally in the form of a tube, that uses a photocathode to convert photons into photoelectrons which are then amplified

Commonly used device for detecting photons by converting them to an electrical signal

(CT) An instrument containing a photoelectric cell and a series of electrodes, used to detect and amplify the X-ray signal that penetrates the body

(PM): A photo cathode having extremely high stability and capable of reading low level light measurements in the entire part of the visible spectrum (as well as some non-visible radiation) PM's are capable of reacting to extremely short duration exposures of light as well as continuously changing conditions of light values These PM's can read, disseminate, boost up signal and pass the information along (in microseconds) to the color computer where these signals are adjusted to conform and create the necessary color balance and depth of color to make the final separation The photomultiplier is located in a group of four in the scanners head and measures the light transmitted through or reflected from the original copy and through corresponding color filters to create the color printers

a device which detects dim light by producing a cascade of electrons

A photodetector, with adjustable voltage, that translates optical tube (PMT) signals into electrical current PMT detectors are used for SSC and fluorescence parameters Increasing the PMT voltage, increases the output signal for a given amount of light

A photomultiplier is a device in which incident photons create measurable electrical pulses The device is based on the photoelectric effect It uses large electric fields to accelerate electrons and, through a cascade sequence, amplify the signal When it is large enough it can be sent to electronic circuitry for analysis and display

A detector that is similar is design to the electron multiplier In the photomultiplier, an ion hits the surface of the dynode, which then emits electrons These electrons strike a phosphorous plate, which then releases photons The signal from the photons are then detected by a photomultiplier
