Describes the diverse techniques used in telescopes for the very wide range of the electromagnetic spectrum covered by pulsar observations. Conventional telescopes for the visible range can be used with suitable high time resolution, while only the lowest energy x-rays can be focussed to form images. Higher x-ray and gamma-ray energies require individual photons to be detected and tracked. The highest energy gamma-rays are detected in Cerenkov air-shower arrays. In contrast to the photon detection of all high-energy radiation, radio telescopes and receivers treat radiation as waves with measurable amplitude and phase, allowing multiple beams to be formed in large phased arrays of radio telescopes.
