Method of measuring and evaluating characteristic of explosion-generated sequential optical signals

摘要

The method of measuring and evaluating characteristic of explosion-generated sequential optical signals according to the present invention is based on measuring conducting by a set of optical fibers, the signals of which (at least some; in the optical, electrical or digital regions) of individual measuring points are merged and subsequently processed by making use of minimization of scattering of detonation velocities computed from side-by-side lying measuring points. In order to increase reliability of evaluation, reference-measuring points are used by interleaving of several merged blocks. According to a known sequence of location of the reference measuring points, it is possible to detect optional drop-out of the optical fiber signals applied to that points (caused for instance by breakage of the fiber). The reference measuring point signals are also not encumbered with parasite pulses of other measuring points.
