Figure 2
Schematic of a parallel-hole collimator (square hole size s, pitch p). Rays produced by a single point source illuminate only certain areas of the sensor (black). The resulting integrated intensity as measured with a pixellated detector is shown as open circles. The dashed line indicates the expected intensity distribution with a full width at half-maximum of R if the collimator is moved in the horizontal plane during the measurement.
