MCP
This abbreviation related to electro-optical detectors stands for micro-channel plate. It describes a thin plate having a huge number of tiny holes or channels. The distance between the holes might be in the 10 to 12 µm range and the hole diameter might be about 6 µm. The inner walls are covered with a high resistive layer. When a photoelectron hits this layer, secondary electrons are emitted. Due to the secondary electron emission characteristics, each channel operates as an electron multiplying device. MCPs are used in gen. 2 image intensifiers to obtain a high gain that can be controlled over a wide range by varying the MCP voltage.
Modulation
The term describes typically the variation of a carrier signal. Related to optical signals and streak cameras, modulation describes the image intensity variation as a function of time or space. If e.g. pulses with a given pulse-width are closely placed side by side, the resulting measurement signal looks like a continuous signal with remaining modulation on its top. The modulation (m) is calculated by measuring the maximum (Imax) and minimum (Imin) intensity.
MTF
The modulation transfer function is abbreviated by MTF. The spatial resolution of an electro-optical system can be described by this function. A spatially and sinusoidally modulated signal is applied on the input of the system. The modulation as function of the spatial frequency is measured.
MultiSegment
MultiSegment allows to take one sequence into the image memory of the camera. This single sequence can be segmented into small parts. With each trigger one part is used for aquisistion. After aquisition the sequence can be viewed or downloaded.
MultiSequence
MultiSequence allows to take several sequences into the image memory of the camera. The whole image memory is separated into several partitions. After the aquisition the single sequences can be viewed or downloaded independently.
