Service can be offered free of charge and the cost of a skin condition measuring device can be reduced by effectively using data on the occasion of obtaining an analysis result by transmitting measurement data by the skin condition measuring device to a server of a company providing a service of analyzing the measurement data. When a request is made from a contractor client to acquire data registered in a measurement data database, authentication is executed based on a contractor ID input from the contractor client. Additionally, when the measurement data database is searched from a contractor database based on the contractor ID, a search level and an access level are obtained. The contractor client is permitted to search the measurement data database within a range of the search level and the access level.

An observation apparatus includes a laser light source, a scanning optical system irradiating a semiconductor device with laser light output from the laser light source, a bias power supply applying a reverse bias voltage of a predetermined voltage between electrodes of the semiconductor device, a sensor detecting an electrical property occurring in the semiconductor device in response to the laser light, and a control system generating an electrical property image of the semiconductor device based on a detection signal from the sensor. The bias power supply gradually increases a magnitude of the predetermined voltage until the predetermined voltage reaches a voltage at which avalanche amplification occurs in the semiconductor device. When the predetermined voltage is increased, the scanning optical system irradiates with the laser light, the sensor detects the electrical property, and the control system generates the electrical property image.

The methods herein utilize polarized light for detecting through holes in substrates. A light source directs light through a first polarization filter having a first polarization axis, wherein polarized light travels from the first polarization filter and toward a substrate. The orientation of the polarized light is changed while traveling through substrate material, and is scattered. However, polarized light traveling through a hole in the substrate remains unscattered. A second polarization filter receives unscattered light and scattered light traveling away from the substrate. The second polarization filter includes a second polarization axis angularly offset from and not parallel with the first polarization axis. As such, the second polarization filter blocks the advancement of unscattered light while the scattered light is not blocked by the second polarization filter. The hole is detected based on an absence of unscattered light surrounded by light traveling from the second polarization filter.
