  • Measuring device for measuring the intensity and/or polarization of electromagnetic radiation, for determining physical properties of a preparation, and for reading information from a storage medium
    Patent number: 5796102
    Abstract: A measuring device for measuring the intensity and/or polarization of electromagnetic radiation, more in particular of light. The measuring device is provided with a tunnel tip arranged facing a body at some distance, which tunnel tip at least partly consists of a semiconductor material. The measuring device further comprises a control unit for obtaining information about the intensity and/or polarization of the radiation by means of a tunnel current, generated under the influence of the radiation in the tunnel tip, between the tunnel tip and the body and/or a surface photovoltage of the tunnel tip, generated under the influence of the radiation.
