    Abstract: Provided is an optical analyzer for performing a feedback control on the amount of light emitted from an LED as a light source, in which the configuration of an optical system is made simple and the degree of freedom in optical system arrangement is secured. An optical member 2 for focusing most of light while discharging part of the light as unfocused light is provided on an optical path from a light casting unit 1 to a sample cell 3. The optical member 2 can be achieved with a simple configuration, for example, two ball lenses spaced apart by a predetermined distance from each other. The light focused by the optical member 2 is cast as measurement light into the sample cell 3. Meanwhile, a second photodetector 5 is arranged at a position where the unfocused light reaches. The second photodetector 5 generates a detection signal in accordance with the amount of light that has entered the second photodetector 5 as monitored light, and a drive current to be supplied to an LED is controlled through a drive current controlling unit 6 and a current source 7 such that the amount of light is maintained at a fixed level.

    Abstract: A method of determining material properties for an object under test is disclosed. The method comprises determining a thickness at a point on the object under test in a non-invasive manner. It also comprises obtaining a terahertz measurement by passing terahertz radiation through the object under test using a terahertz emitter and detecting the terahertz radiation using a terahertz detector. Finally, it comprises determining an optical property at the point on the object under test using a measurement value from the terahertz emitter and the terahertz detector and a measured value for the thickness at the point.

    Abstract: An apparatus and method for detecting at least one component gas in a sample includes a radiation source for providing radiation along an optical path in a pre-selected spectral band having at least one absorption line of the component gas to be detected and an optical detector for detecting radiation at the optical path. A sample chamber is positioned in the optical path between the source and the optical detector to contain a quantity of a sample gas. At least one gas cell enclosing an amount of the gas to be detected is fixedly positioned in the optical path in series with the gas chamber. A mathematical relationship is determined between the detected radiation and the concentration of a sample gas filling the sample chamber.
