Dmac ... the amount of energy that is transferred to the film or sensor is responsible for the conversion of light energy into either the electrical signal or chemical change in the emulsion.
This is a vector force. Vector forces are subject to trigonometric functions. Diffraction changes the angle of impingment. Angle changes are trig changes and correspondingly reduce the force applied @ AI. This is the reason that sensor technology incoporates microlenses, in an effort to refract the oblique light to a more direct impingement of the sensor. More direct vs. more oblique is preferrable for the greatest transmission of force. Ideally, a sensor would not lie in a flat plane, but be curved in order to receive the maximum energy from a perpendicular impingement at all points ... but I digress.
BTW ... no references ... I just made it up.
You know, that whole vector quantity thing.
Wikipedia shows a couple of formulas @ diffaction. One is relative to the airy disc computation, the other @ sin of theta. Deeper research on the matter will reveal the continued trig function ... but you\'ll have to do that on your own. This is why sharpness (airy disc overlap) and contrast (applied energy @ vector force) are related by the effects of diffraction. Two different issues.
