    摘要： A method of monitoring pressure of a gas species up to at most a predetermined maximum pressure value is disclosed. The method includes exposing the gas species to transmission of laser light, periodically modulating the wavelength of the laser light over a wavelength band including at least one absorption line of the gas species, optoelectrically converting the transmitted laser light, thereby generating an electric output signal, performing at least one of first filtering the electric output signal with a filter characteristic having a lower cut-off frequency not lower than a transition frequency and of second filtering the electric output signal with a bandpass filter characteristic having an upper cut-off frequency not higher than the transition frequency and a lower cut-off frequency above the modulation frequency of the periodic wavelength modulation. The output of at least one of the filterings is evaluated as a pressure indicative signal.

    摘要： An apparatus for detection of the existence of a film on a surface comprises a lens, a light emitter and a light sensor. The light emitter is preferably disposed in spaced relation to the lens and is configured to emit light toward the lens such that the light is incident thereupon. The light sensor is also preferably disposed in spaced relation to the lens and is mounted adjacent to the light emitter. The light sensor is configured to measure light reflected back from the lens. The presence or absence on the film on the surface is based upon the amount (i.e., intensity) of light that is reflected back from the lens. The apparatus may further comprise a temperature sensor or atmospheric sensor for measuring a temperature of the lens and atmospheric conditions in order to determine whether conditions are appropriate for the formation of ice, frost and other frozen contaminants.

    摘要： The present invention aims at reducing background noise derived from a substance that is present in the vicinity of a target substance such as a DNA and protein and attached to the surface of a substrate without an effect on a fluorescent dye labeling the target substance. The substrate that has a probe and is capable of interacting with the target substance is irradiated with noise removing light such that an evanescent field is generated on the surface of the substrate. A target substance and a foreign particle, which are non-specifically stuck to the surface of the substrate, are decomposed by the evanescent field generated by the irradiation with the noise removing light. The evanescent field present near the surface of the substrate has almost no effect on the probe. It is possible to reduce the background noise derived from the substance that is present in the vicinity of the target substance and attached to the surface of the substrate and suppress effects on the probe and the target substance interacting with the probe.
