(4.7)
When the central maximum of one image falls on the first minimum of another image, the images are said to be just resolved. This limiting condition of resolution is known as Rayleigh’s criterion.

The Diffraction Grating
The diffraction grating, a useful device for analyzing light sources, consists of a large number of equally spaced
parallel slits. |

The Diffraction Grating
Intensity versus sinθ for a diffraction grating. The zeroth-, first-, and second- order maxima are shown.

The Diffraction Grating
A small portion of a grating light valve. The alternating reflective ribbons at different levels act as a diffraction grating, offering veryhigh-speed control of the direction of light toward a digital display device.
