Rayleigh criterion |

criterion, Rayleigh Observation first made by Rayleigh that the images of two point objects will be resolved when the central maximum in the diffraction pattern of one image coincides with the first minimum of the diffraction pattern of the other image. For a perfect eye, with a 2 mm pupil, this criterion corresponds to a theoretical tolerance in focusing equal to about 0.075 D. See Airy's disc; diffraction; limit of resolution.

| This provides considerably higher angular resolution and
dispersion for the MDCS. To answer these questions MAP will produce an accurate full-sky map
of the cosmic microwave background temperature fluctuations with high
sensitivity and angular resolution. Both horizontal [1] and vertical focusing lead to a
loss of angular resolution via peak broadening, for they increase the
vertical divergence of the beam incident on the sample. |
