It is also compensated for white light illumination working with large apertures. Unfortunately a half-wave plate assuming the compensation is not achromatic. Moreover a calcite crystal used in this interferometer is breakable. It will be shown that an association of two crystal plates whose birefringences have opposite sign offers an alternative solution. These crystal plates can't be either optically active nor too fragile and their birefringences ratio should not be too large. In addition the crystal placed in front of the objective must be more birefringent then the second one. Authors propose a combination of KDP and F2Mg crystals and have tried to achieve the best possible compensation. It is not however possible to fully compensate such a system to second order. This particular crystal association can not be either zero and second or first and second orders compensated. It has been shown that the best solution consists of a partial compensation of the second order assumed either in the direction of the shear or in the direction perpendicular to the shear. Using the crystal materials chosen as above a nearly optimized interferometer was realized without being entirely zero order compensated.","PeriodicalId":286899,"journal":{"name":"Nouvelle Revue D'optique","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131461345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lyot: the coronagraph, the birefringent filter and the polarimeter. However it differs completely from the coronameter. It is possible to study many emission lines by tuning the birefringent filter.

In 10 s of time, the polarimeter measures in a 5\" diameter spot three quantities: monochromatic intensity, polarization ratio p, angular deviation from the limb: e. The instrument gives a polarimetric map of the prominence. Owing to its performances, it is possible to study fast moving objects such as active prominences.","PeriodicalId":286899,"journal":{"name":"Nouvelle Revue D'optique","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128103604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hologram of a plane wave recorded with a parallel reference beam is a set of equidistant layers inside the emulsion. When reconstructing this hologram, each layer acts as a narrow mirror, with a broad diffraction lobe. However, the large number of layers produces a «grating effect» and constructive interference occurs in only one direction, that corresponding to the reconstructed image. When the reconstruction beam has a different direction or wavelength than that of the reference beam, the angular or chromatic selectivity has been worked out taking into account the different rotations undergone by the diffraction direction and grating effect direction. The influence of emulsion shrinkage and absorption is also studied. It is shown that absorption has a great importance for back carrier holograms, but is negligible for transmission hologram.","PeriodicalId":286899,"journal":{"name":"Nouvelle Revue D'optique","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125539628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

U. V. spectral range. They are working generally at normal incidence, the angle between the two fixed beams being chosen less than 70° in order to reduce the amount of astigmatism (ASM 50 [2] or H 20 monochromators manufactured by Jobin-Yvon). However such type of mountings are presently limited at wavelengths longer than 800 A by the low efficiency of the reflecting power of the coatings generally used. At high incidence angle, we find low efficiency caused by astigmatism, accompanied by an equivalent reduction in energy throughput. Efforts have been made to correct this astigmatism in part by using a holographic grating. However, for short wavelengths at grazing incidence, a spherical concave holographic grating cannot have much effect on the astigmatism. This has led us to using toroidal blanks.","PeriodicalId":286899,"journal":{"name":"Nouvelle Revue D'optique","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130247060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This instrument, based on the atomic ionluminescence phenomenon, gives, like a cine-camera, a characteristic picture of each sputtered layer, a few angstroms thick. Moreover, when several elements are present in the target, it is possible to obtain, almost at the same time, the characteristic pictures of two different elements that we want to locate at the surface. So as to show the possibilities of this apparatus, we present some photographs taken from a film which correspond to the superficial concentration of the two elements of a Al/NaCl target.
