The influence of binocular vision on the visual Mach effect in microscopy

Chemical microscopy

“…Reynolds (11,166) has described a' microscope, fitted with a sensitive image intensifier unit, capable of observing directly t,he location of radioactive tracers in a specimen. A simple microfluorimeter is described by Stoward (187), aiid Barer (10) tells how t o obtain the maximum intensity of fluorescence by illuminating t,he specimen using both incident and transmitted illuminat'ors.…”

“…A table listing 93 radionuclides for which standard preparations are available was published; also included is information concerning sources of supply and use (166). The same author is now engaged in a Y R C sponsored project surveying the needs and interest in radioactivity standards, as well as …”

“…The Mach effect, as was noted earlier, was the subject of a review by Welford (11). Rowe has published two articles dealing with this effect (166,167). In one he finds that small focusing errors affect the position of the Mach bands, and in the other he shows that there is little difference in the Mach effect as observed using monocular or binocular microscopes.…”

“…In a method of absolute standardization using liquid scintillation counters, the observed output was compared with that produced theoretically from the beta ray spectrum for a number of nuclides; activities determined for three low energy emitters: tritium, carbon-14, and chlorine-36 agreed well with standards (84) . General information concerning standards, accuracy, certification, and types available are described in a publication from the Radiochemical Centre, Amersham (14®)• A table listing 93 radionuclides for which standard preparations are available was published; also included is information concerning sources of supply and use (166). The same author is now engaged in a NRC sponsored project surveying the needs and interest in radioactivity standards, as well as…”
