Abstract: 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.

Abstract: The invention relates to a device for inspecting eggs for the presence of blood. The device comprises a light source in order to pass light at a first wavelength which is not selectively absorbed by blood and light at a second wavelength which is selectively absorbed by blood through an egg to be inspected. Furthermore, the device comprises detection means for converting the light transmission through the egg to be inspected for each of the two wavelengths into corresponding signals, each of the said signals being representative of the light transmission at the relevant wavelength. The device also comprises signal-processing means which are transmission associated with the first wavelength and the light transmission associated with the second wavelength based on the signals emanating from the detection means and to emit a decision signal which is representative of the decision whether or not an egg contains blood on the basis of this ratio. According to the invention, the light source comprises one or more identical LED's (Light Emitting Diode) for generating light which passes through the egg. In use the one or more LED's emit light within a certain narrow spectrum, which spectrum comprises both the first and the second wavelength.

Abstract: A defect inspecting apparatus of the invention solves a problem that in a defect inspecting apparatus, because of improving detection sensitivity of a microscopic defect by reducing a detection pixel size, a focal depth becomes shallow, a height of imaging is varied due to environmental change and the detection sensitivity of a defect becomes unstable. This apparatus comprises an XY stage, which carries a substrate to be inspected and scans in a predetermined direction, and a mechanism having a system of irradiating a defect on the inspected substrate at a slant and detecting the defect by a detection optical system disposed on the upper side, which corrects a height of imaging in real time for change in temperature and barometric pressure in order to keep the imaging in a best condition.

Abstract: A thermoelectrically cooled surface-enhanced Raman spectrometer sensor system and method for monitoring of volatile organic compounds in gas, liquid, and soil environments. The sensor system comprises a means for providing an inert gas, a thermal desorption tube containing an adsorbate, and a sample chamber with a SERS structure. For liquid and soil environments, the sensor system also comprises a manifold having a semipermeable membrane for separating moisture from an analyte. An optical module mounted to the sample chamber directs an optical excitation signal for irradiating the SERS structure and receives a SERS optical emissions signal. Such optical emissions signal may be detected by a spectroanalysis system and correlated to a particular analyte by a control processor, which generates an alert signal containing a message that the presence of analyte has been detected. The control processor may also activate warning device, such as an audible siren or a visual alarm.
