DYNAMIC CONTRAST RATIO
Maximum modulation bandwidth (50MHz) dynamic contrast ratio (CR) is obtained with a focussed beam diameter of 31mm. The typical MTF (depth of modulation) curve for the M1067 is shown at left. For larger beam diameters, the abscissa scales linearly. The value of M from the curve may be used to determine the sine wave contrast ratio at a particular modulating frequency according to the relation:
CR = 1+M/1-M
For digital, on-off modulation, the CR will be greater than the value calculated from the above equation.
