We propose to complete deep ISO integrations of CFRS fields which have already been widely studied by the largest spectroscopic survey of faint galaxies available up to date. Deep imagery/photometry are available in B, V, I and K bands while about 50% of the I=22.1 galaxies have been spectroscopically measured. Moreover a significant part (30%) of these fields have been covered by deep HST imagery. The ISO observations of two additional fields (CFRS2215+00 and CFRS2215+00) combined with the already planned observations of CFRS1414+52 and of CFRS0300+00 (PROPID: HIZ_GAL), would provide an unique sample of about 100 ISO sources with spectroscopy, deep imagery (including K-band) and detailed morphology from HST. This program will also be used as a template to the deep surveys on blank fields planned in the core program. Our aim is to investigate the infrared properties of field galaxies including (1) the evolution of the dust properties in field galaxies up to z=1 and the consequence on to the estimation of the global star formation rate and its evolution; (2) the faint population of AGNs which dominates the microJy radio counts and represents a significant fraction of the overabundant population of faint blue galaxies. We intend to carry out deep observations in 4 wavelength ranges, at 5-8/12-18 microns with ISOCAM and 60/90 microns with ISOPHOT. Our goal is to get a better understanding of the dust emission in distant normal galaxies as well as in AGNs and its link with optical and radio emission. Several broad band measurements are required to understand the relative influence of hot/cold dust in galaxies as well as to disentangle dust emission from non thermal emissions in AGNs. We believe that using fields where a considerable amount of work has already been done will put us in a good position to rapidly provide new and fascinating results just after the ISO observations.
