Abstract

Abstract The MIC photon counting detector developed at UCL has been upgraded to allow time resolved spectroscopic optical data to be acquired on periodical sources such as pulsars. First observing trials have been carried out on the Crab pulsar. The detector was phase locked to the pulsar period and a temporal resolution of 41.4μs employed. The phase locking allowed the co-addition of time slices over a large number of pulsar periods building up quantifiable spectroscopic data when observing in a flux limited regime.
