Electron detection characteristics of slow-scan CCD camera
The characteristics of two single-crystal YAG-based slow-scan CCD (SK) cameras are measured and analyzed for various electron accelerating voltages. A stream-lined procedure for characterizing electron cameras is described, especially, the procedures for the measurement of modulation transfer function (MTF) and detector quantum efficiency (DQE). The limiting factors on the DQE of the SSC camera...
متن کاملCCD Camera Gain Measurement
The gain of a CCD camera is the conversion between the number of electrons ("e-") recorded by the CCD and the number of digital units ("counts") contained in the CCD image. It is useful to know this conversion for evaluating the performance of the CCD camera. Since quantities in the CCD image can only be measured in units of counts, knowing the gain permits the calculation of quantities such as...
متن کاملMethods for CCD Camera Characterization
In this paper we present methods for characterizing CCD cameras. Interesting properties are linearity of photometric response, signal-to-noise ratio (SNR), sensitivity, dark current and spatial frequency response (SFR). The techniques to characterize CCD cameras are carefully designed to assist one in selecting a camera to solve a certain problem. The methods described were applied to a variety...
متن کاملDigital Fluorescence Imaging Using Cooled CCD Array Cameras invisible
The progress in solid state technologies has led to a range of CCD cameras from inexpensive video cameras to expensive scientific digital camera systems. The best choice (best value for money) depends heavily on the application. A state-ofthe-art camera’s performance is limited by the fundamental laws of nature. The various noise sources (photon statistics, thermal, readout and quantization) ar...
متن کاملCCD camera full range pH sensor array.
Changes in colors of an array of optical sensors that responds in full pH range were recorded using a CCD camera. The data of the camera were transferred to the computer through a capture card. Simple software was written to read the specific color of each sensor. In order to associate sensor array responses with pH values, a number of different mathematics and chemometrics methods were investi...
