Optical Transient Recorder
To meet the demanding requirements of optical signal detection, the OTR was developed to reach the best dynamic range together with high temporal resolution at fast signal repetition rates. For the first time, analog detection of the photomultiplier current and single photon counting is combined in one acquisition system.
Usually the detection systems are optimised for measuring low level light intensities using the single photon counting technique, but at higher light levels this approach gives a nonlinear signal response. An analog measurement of the photomultiplier current is therefore necessary to increase the dynamic range.
The Licel transient recorder comprises a fast transient digitiser with on board signal averaging, a discriminator for single photon detection and a multichannel scaler together with preamplifiers for both systems.
