During the last few years, the significance of optical astronomy has again increased as a result of an employment of novel detectors which can improve the efficiency of a telescope considerably. The principles of operation involved in the new methods of optical astronomy are examined. A certain spectral range is selected from the 'white light' received from a star. A detecting device is used to transform the light into an electrical signal. A flow of electrons emitted by a photocathode is amplified with the aid of a photomultiplier. Silicon diodes can also be used to transform the received light into an electric current. The use of multichannel devices using a one or two-dimensional array of detectors makes it possible to enhance the detection efficiency considerably. Attention is given to the Digicon, charge-coupled devices, microchannel plates, image enhancers, an electronographic camera, and TV systems.
