CONSIDERATIONS ON THE OPTICS OF THE INTEGRATING SCHLIEREN INSTRUMENT.
Abstract
An analysis is presented of the optics encountered in the integrating schlieren arrangement as first described by Resler and Scheibe. Expressions were developed for the signal which will be received on the photomultiplier, both for the instrumentation using an inclined knife edgeAND FOR THAT WHICH USES A VERTICAL KNIFE EDGE. Attention is given to the conditions which must be satisfied to guarantee that the response of the photomultiplier shall be proportional to the difference in refractive index at the beginning and the end of the test section. The signal to be expected in the case of a sudden discontinuity in refractive index, which is partly reflecting, partly transmitting, was calculated and is compared with the signal obtained with a continuous change of refractive index. Throughout the analysis it is supposed that lens aberrations can be neglected and that diffraction phenomena may be left out of account. (Author)
