    摘要: An object of the present invention is to provide a scanning electron microscope including decelerating-electric-field forming means for decreasing the energy of a beam of electrons reaching a sample, and being capable of selectively detecting BSEs with high efficiency. To this end, the scanning electron microscope including the decelerating-electric-field forming means has a detector for detecting electrons. The detector includes a part for receiving the electrons at a position which is positioned outside trajectories of SEs accelerated by the decelerating-electric-field forming means, and which is further away from the optical axis of the beam of electrons than the trajectories of the SEs.

    摘要: A non-destructive inspection apparatus has a radiation source, a radiation detector, a radiation source diver, a detector driver, a drive controller, a delay circuit, a radiation signal processing circuit, a memory, a computer, a display device, and an input device. The radiation detector consists of one-dimensional or two-dimensional array of detectors having a long collimator whose pores are in parallel with the radiation angle of the radiation emitted in an angular pattern from the radiation source, whereby a transmission image of a large size structure can be obtained at high speed and with a high resolution. Furthermore, the detect position in an inspection object can be specified by analyzing a plurality of specified transmission images using the inspection apparatus.
