Abstract: The discovery of pulsars in 1968 heralded an era where the temporalcharacteristics of detectors had to be reassessed. Up to this point detectorintegration times would normally be measured in minutes rather seconds anddefinitely not on sub-second time scales. At the start of the 21st centurypulsar observations are still pushing the limits of detector telescopecapabilities. Flux variations on times scales less than 1 nsec have beenobserved during giant radio pulses. Pulsar studies over the next 10 to 20 yearswill require instruments with time resolutions down to microseconds and below,high-quantum quantum efficiency, reasonable energy resolution and sensitive tocircular and linear polarisation of stochastic signals. This chapter is reviewof temporally resolved optical observations of pulsars. It concludes withestimates of the observability of pulsars with both existing telescopes andinto the ELT era.
