A flash discharge tube is a light source that is designed to be operated by a condenser discharge, and thus to produce flashes of very high intensity and very short duration. It may be operated in conditions in which these flashes are isolated from one another by relatively long periods of time, or in which they follow one another in rapid succession.The high current density conditions of operation result in the production of light of excellent spectral quality, whilst the flash duration is so short as to be capable of arresting very high speed motion. It is not practicable, within the compass of a paper such as this, to refer to all the manifold purposes to which flash discharge tubes can be usefully applied.It has, therefore, been the author's endeavour to discuss flash tube applications on broad rather than specific lines and to cite particular applications as examples of general practice. |
