Class SinglePulseExtraction

java.lang.Object

fact.photonstream.SinglePulseExtraction

All Implemented Interfaces:

stream.Processor

public class SinglePulseExtraction
extends Object
implements stream.Processor

Extracts a list of arrival slice positions of photons for each pixel time line.

Only a fraction of the whole time series is analysed, this is called extraction window. Artifacts of the *extraction window* borders are removed from the lists of found single pulses. This is implemented by introducing the *output window*.

slices: whole time series |.......................................................................| | | | |................ extraction window .................| | | | <---------- length = 225 ------------------------> | | | | | | | | |.. output window ..| | | 0 20 | <- length=100 -> | 245 300 30 130
