In the mean-field approximation, the equations of OB system are solved numerically. It is shown that the dispersion has remarkable influence on the output intensity and the risetime of switching. In the \"bad cavity case', it is more striking. Under the different cavity conditions, the dispersive spectra of switching output are given.","PeriodicalId":322470,"journal":{"name":"Marketplace for Industrial Lasers","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126966395","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}

In principle, the system can be used for performing an arbitrary linear transform and multiplication of matrices, as well as extracting the features of a pattern. In this system all the spacings between the input, lens, mask and output planes are equal to the focal length of the Fourier lens, The point-spread function is represented by the process of lightwave propagating through the optical system and modulating in the mask. The mask is produced by using computer-generated-hologram techniques. In experimental research, the system is tested by Walsh-Hadamard transform, matrix multiplication and geometric moment integral. The experimental results show that, the measured values of the above integrals are in agreement with the theoretical calculations.","PeriodicalId":322470,"journal":{"name":"Marketplace for Industrial Lasers","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126658897","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}
