ABSTRACT:
An optical sampling apparatus has an electron beam generating apparatus which generates an electron beam by irradiating a cathode with an optical signal, a deflection electrode which deflects the generated electron beam, a sampling slit which transmits a part of the deflected electron beam, and a charge detection section which detects the quantity of charges or accumulated current of the transmitted electron beam. It is possible to perform accurate sampling in a high band.
