摘要： A probing device includes a minute probe in which at least an end portion is formed by conductive material, a cantilever having one end to which the probe is attached, and another end fixed to a moving member movable relatively to a sample in each direction of X, Y and Z, a unit for moving the moving member relatively to the sample, a transducing unit for generating information of voltage or current by means of light, a connecting unit having a low electric resistance, for connecting the transducing unit and the end portion of the probe, a detecting unit for detecting a change in a physical amount occurring in the cantilever by a force caused between the probe and the sample by a relative proximity of the moving member to the sample, and a voltage measuring unit for measuring a voltage at a measurement point on the sample, which is determined based on an output of the detecting unit, by way of the transducing unit when the probe is contacted with the measurement point. By the constitution, it is possible to realize a voltage measurement with both an enhanced space resolution and an enhanced time resolution. Also, by using the probing device in an integrated circuit testing apparatus or system, it is possible to realize a stable probing to a minute wiring without increasing an electrical load with respect to the minute wiring and thus contribute to an improvement in the precision of a voltage measurement.

摘要： Disclosed is an authentication apparatus easily achieving convenience and high accuracy in authentication. The authentication apparatus has an authentication accuracy simulation section that simulates authentication accuracy and also has a registration information setting section that sets an ID and biometric information input as registration information. The authentication accuracy simulation section uses an ID and biometric information that has been input as registration information by a user at the time of registration and the registered registration information to simulate authentication accuracy with which the user is authenticated. When the authentication accuracy simulated by the authentication accuracy simulation section does not satisfy a predetermined condition, the registration information setting section rejects registration of the ID input as the registration information.

摘要： An image forming apparatus causes an illuminating unit and an imaging unit to equally split a predetermined exposure time into a plurality of split exposure times, and acquire an image with illumination and an image without illumination in each of the split exposure time. A luminance difference image for a particular split exposure time is calculated by subtracting the image without illumination from the image with illumination of the exposure time. The luminance difference images of all the split exposure times are integrated.
