专利汇可以提供Image correlator tube with secondary transmission of collimated rays专利检索,专利查询,专利分析的服务。并且An image orthicon type device is disclosed for electrooptical integration and correlation systems. A photoemissive cathode and a dynode electrode of an electron conductive dielectric material provide for direct emission of secondary electrons from collimated light input signals to impinge on an insulated target member. The normal photoelectric emission current is multiplied by a factor inherent in direct secondary electron emission by the dynode electrode and becomes a linear function of the accelerating potential between the photocathode and dynode for processing time variable modulating signals. An axial focusing magnetic field is utilized. The dynode electrode arrangement may be constructed as a separate sealed compartment in the overall device.,下面是Image correlator tube with secondary transmission of collimated rays专利的具体信息内容。

1. An electrooptical correlation system comprising: means to collimate and direct radiant energy signals in a beam to traverse an acoustic optical delay line modulator; said modulator having means for providing a first input electrical corrElation signal to modulate the emergent signal beam pattern; photoelectric conversion and translation means for correlating said beam signals comprising: an image correlator tube having an electron image section disposed at one end; a photoemissive cathode for emitting photoelectrons disposed at one end of said section; a target member disposed at the opposing end of said section; a dynode electrode member of an electron conductive material disposed between said photocathode and said target member; means for biasing said dynode electrode member with a second input electrical correlation signal; and means for electronically scanning the reverse side of said target member, collecting and integrating the product of all said electrical signals to derive a correlated electrical output signal.
2. An electrooptical correlator system according to claim 1 wherein said dynode electrode member is selected of a material from the group consisting of magnesium oxide, aluminum chloride and potassium chloride.
