Contamination of such sensors in space is a critical issue because it degrades the capability to detect or identify objects of interest through stray light scatter into the field-of-view (FOV), signal attenuation, false targeting, defocussing of the target image, etc. The magnitude and structure of the noise contribution from contamination must be weighed against the magnitude and structure of other noise components in order to determine its importance. Clearly, the problem is system design dependent and a flexible means of simulation is required to address the issue. Many previous models have dealt only with pieces of the problem; PEARLSS (Particulate Effects Analysis on Response Levels of Space-borne Sensors) is a model which deals with contamination generation, migration, deposition, and resulting optical degradation in a single 'end-to-end' code.","PeriodicalId":184695,"journal":{"name":"Space Optics for Astrophysics and Earth and Planetary Remote Sensing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130841514","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}

We assume that an incoherent light source (object) illuminates an observing site and that the optical wave field around this site consists of an ensemble of plane waves with uncorrelated amplitudes. This is a reasonable assumption when the observation volume is small or an appropriate transform lens is placed between the object and observation area. The theory predicts that three-dimensional (3-D) Fourier transformation of the 3-D spatial coherence function of the optical wave field gives the 3-D energy density function, a function of a 3-D spatial frequency or a wave vector, associated with the object[1]. Under the assumption stated above, the wave vectors assign particular directions of propagation and wavelengths of the plane waves that emanate from the particular positions in the object. Thus, the density function fully specifies the spectral image information of the object, i.e. the spatial distribution of radiation and the spectral contents comprising the radiation. Since the present method is an extension of Fourier spectroscopy to imaging spectroscopy[1], it inherits the desirable properties of the multiplex and throughput advantages.","PeriodicalId":184695,"journal":{"name":"Space Optics for Astrophysics and Earth and Planetary Remote Sensing","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126542167","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}

For the former operation, the masks may be rotated (1) to correct axisymmetric errors or remain stationery to provide discrete area removal.

In addition to increased accuracy, the metrology is required to keep pace with the shorter fabrication cycles of advanced figuring techniques such as computer-controlled polishing. As a result, there is an emphasis on:\u0000 1) Integrated testing approaches. Instruments such as interferometers must be interfaced with the polishing machine and the performance prediction software in order to minimize the time required to perform a full metrology cycle.\u0000 2) Redundancy in testing. Each surface parameter is measured in two independent, complementary test methods using unique test equipment. This minimizes the risk of systematic errors and reduces measurement uncertainty.\u0000 3) Overlapping measurement bandwidths. Test methods used to evaluate the surface errors are selected to ensure all spatial periods are adequately sampled and a complete characterization of the mirror surface is obtained.","PeriodicalId":184695,"journal":{"name":"Space Optics for Astrophysics and Earth and Planetary Remote Sensing","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129107293","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}
