The mechanisms of image recording with coherent and partially coherent light are well understood and many examples are to be found in the rather extensive literature. The deleterious effects in the recordings of coherent images arise from the specific functional form of the amplitude impulse response and the non-linearity of the coherent image forming and recording process. Several groups of workers have used apodisation of diffraction limited optical systems to produce acceptable amplitude impulse response functions. Satisfactory results have been obtained. Current progress in this important aspect of coherent image recording will be reviewed.
