1949 C-R-TuBE APPLICATIONS 85
CONCLUSION
While it has not been possible to give here a complete description of all cathode-ray tube applications considered in optics and photography, it should now be obvious that cathode-ray tubes and oscillographs are valuable tools for solving many technical problems. Because of lack of space, we have not been able to consider many of these in the detail they deserve or to include many which have been developed outside of our Laboratories.
It is hoped that this brief consideration of some applications will stimulate the use of these oscillographic techniques in as wide a range of problems as possible.
