Fraunhofer diffraction has been the leading form used in space spectroscopy research thus far. However, Fresnel diffraction occurs when the detector is relatively close to the diffracting object ...

Point out the Fraunhofer diffraction pattern. Increase the aperture size by turning the two knobs of the variable aperture. Point out the Fresnel diffraction pattern. Turn off the laser. Additional ...

IN a recent letter by J. Dyson concerning an optical analogue of X-ray and electron diffraction patterns1, no reference is made to the previous experiments made with other models for exhibiting ...
