LSM 510 ANNEXLSM 510 META Monitor Diode Carl Zeiss03/06 B 45-0021 e 8-21The following image is an example of the reduction of correlated noise. The low frequency noise hasbeen generated artificially.The image in the upper left corner shows the PMT image plus noise, the image beneath this (upper rightcorner) shows the signal of the diode expanded to 512 x 512 pixels (noise without object information).The two images below show the ratio of the PMT and diode signal (left) and the sum of all signals (right).The sum-image does not contain any information and can therefore be neglected.To get a ratio image like the one shown here, Detector Gain, Amplifier Gain, Amplifier Offset of the PMTchannel, Gain and Offset of the diode channel, Gain and Offset of the ratio channel must be set in thecorrect way.Each of the parameters summarized effects either the amplification of the ratio image, or the contrast ofthe ratio image, or the quality of the noise reduction.Fig. 8-8 Image Display window
