| Title | Dyson, James: certificate of election to the Royal Society |
| Description | Citation typed |
| Citation | Distinguished for his contributions to optics, which include the first long working distance high N.A. micro-objective without aspheric surfaces; two new forms of interference microscope for transparent and two for opaque objects; the first direct observation (by phase-contrast microscopy) of the true contact area between solids; methods of photographing, via their diffraction spectra, the individual defects in bubble rafts; a discussion of the aberrations of the focussing X-ray microscope; methods of reducing these aberrations; catiotropic UV cameras for spark photography; an image-splitting microscope for precise diameter determinations; and methods of defining a straight line interferometrically and also by circular and even spiral diffraction gratings. He is introducing these methods of great precision into engineering practice. |
