    Abstract: A spectrometric system has a primary channel with a signal waveform and a reference channel with a signal waveform. A digital representation of the primary signal waveform and a digital representation of the reference signal waveform to provide a digital output representing the primary signal at datum points synchronized with the reference signal are processed by computing the Fourier transform of the primary signal waveform and using a fast reverse non-uniform discrete Fourier Transform technique to compute the reverse non-uniform discrete Fourier transform of the Fourier transform of the primary signal waveform to provide the digital output representing the primary signal at datum points synchronized with the reference signal.

    Abstract: A surface inspection of the system applies a first oblique illumination beam and may also apply a second illumination beam to illuminate a surface either sequentially or simultaneously. Radiation reflected or scattered is collected by preferably three collection channels and detected by three corresponding detector arrays, although a different number of channels and detector arrays may be used. One or both illumination beams are focused to a line on the surface to be inspected and each line is imaged onto one or more detector arrays in the up to three or more detection and collection channels. Relative motion is caused between the lines and the surface inspected in a direction perpendicular to the lines, thereby increasing throughput while retaining high resolution and sensitivity. The same detection channels may be employed by detecting scattered or reflected radiation from both illumination beams. Fourier filters may be employed to filter out diffraction at one or more different spatial frequencies.

    Abstract: A detection apparatus includes a sample holding section, an irradiation means, a detection means, a calculation means, and an evaluation means. The irradiation means irradiates a substance held in the sample holding section with a THz wave. The detection unit detects a THz wave passed through or reflected from the substance. The calculation unit determines a frequency dependence of a property of the substance with respect to the irradiated THz wave and then calculates a slope of a straight line or a slope of a straight line obtained by straight-line approximation of the frequency dependence of the property of the substance. The evaluation unit evaluates the state change of the substance by comparing a previously-obtained slope of a straight line of the frequency dependence of the property of the substance in a standard state and the slope of the straight line of the substance calculated.
