A Method of Estimating the Scatter of Red Cell Populations from Their Diffraction Patterns
Eric Ponder · Journal of Experimental Biology · 1929
ABSTRACT All the existing methods for determining the diameter of red cells by the observation of the diffraction patterns which they produce are concerned with the determination of mean diameter only, and rest upon expressions which relate the position of the various maxima and minima to the diameter of a number of circular disks of uniform size (Pijper, 1919, 1923, 1925; Millar, 1926; Allen and Ponder, 1928). As is well known, the red cells which produce the diffraction patterns are not of uniform diameter, but it is assumed in the use of these methods that the diameter given by the formulae is the mean diameter of the red cell population.
