Abstract: A method for signal detection with a gas analysis system (1, 1′) includes a radiation source (3); a gas measuring section (9) containing gas to be measured; a Fabry-Perot interferometer (13); a thermal sensor (17) configured to cause a change in voltage between electrodes with electromagnetic radiation falling thereon and arranged such that radiation released by a second interferometer mirror falls on the thermal sensor. The method includes irradiating the gas measuring section with radiation source radiation, continuously increasing or decreasing a distance of interferometer mirrors during a generating of time signal pulses at a constant period of time from one another. After a predefined number of time signal pulses, the voltage generated between the electrodes is detected and stored as a measured signal value. After a further predefined number of time signal pulses, the voltage generated between the electrodes is detected again and stored as a measured signal value.

Abstract: A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.

Abstract: A light radiating portion radiates light with wavelength λ1 having predetermined absorptivity for an object and light with wavelength λ2 having smaller absorptivity for the object than the wavelength λ1, to a target, so as to scan in 2-dimensional directions. A light receiving portion receives scattered lights reflected by the target based on light with wavelength λ1 and light with wavelength λ2. A measuring portion generates information used for detection of the object at the target, based on difference between the two scattered lights with wavelength λ1 and wavelength λ2 received by the light receiving portion. An output portion outputs whether or not the object is present at the target, by 2-dimensional area information, based on scanning by the light radiating portion and information generated by the measuring portion.

Abstract: There are provided an atomic absorption photometer and an atomic absorption measurement method which can easily perform background correction in a short time period by using a plurality of types of methods while suppressing the amount of samples consumed. Background correction is performing by using each of the D2 lamp method, the Zeeman method, and a self-reversal method, according to measurement data in each of measurement periods T41 to T46 obtained in one data acquisition cycle. Background correction is performed on the common measurement data (atomic absorption data) obtained in the atomic absorption measurement period T41, by using the measurement data (background data) obtained in each of the first to third background measurement periods T44, T46, and T42.

Abstract: With a microspectroscopy device provided with an objective lens with a high numerical aperture, a defocus arises from thermal drift, etc., necessitating auto-focusing. Conventional auto-focus based on through-focus image acquisition takes time, and thus, it cannot be applied to continuous measurement over a long time wherein high-speed sampling is carried out. The present invention addresses this problem by having a defocus-sensing beam that has either defocus or astigmatism fall incident on the objective lens. Since how the image of the spot of the beam for defocus sensing blurs differs depending on the orientation of the defocus, real-time detection of the amount and orientation of defocus becomes possible, and high-speed realtime auto-focus becomes possible.
