Abstract: An off-axis optical system having a rectangular aperture stop to control rays of incident electromagnetic radiation passing through the optical system along an optical path is provided. The optical system includes one or more optical surfaces along the optical path, each surface being configured to change a direction of each ray on the surface based on a location of the ray relative to the surface. At least one of the surfaces is conjugate to and has the same shape as the rectangular aperture stop. In one embodiment, each optical surface is shaped to avoid vignetting the rays. In one embodiment, the optical system is a three-mirror anastigmat (TMA) and includes a concave primary mirror to collect and focus the electromagnetic radiation; a curved secondary mirror to reflect the electromagnetic radiation focused by the primary mirror; and a concave tertiary mirror to focus the electromagnetic radiation reflected by the secondary mirror.

Abstract: A measurement system includes a light source having semiconductor sources, a multiplexer, and one or more fused silica fibers configured to form an output optical beam having one or more optical wavelengths modulated at a modulation frequency. A light beam set-up includes a monochromator forming a filtered optical beam. A measurement apparatus delivers the filtered optical beam to a sample. A receiver receives a spectroscopy output beam generated from the sample by the filtered optical beam. The receiver is configured to use a lock-in technique that detects the modulation frequency, and to generate first and second signals responsive to light received while the light source is off and on, respectively. The measurement system improves a signal-to-noise ratio of the spectroscopy output beam by differencing the first and second signals. The receiver processes the spectroscopy output beam using chemometrics or multivariate analysis to permit identification of materials within the sample.

Abstract: A total reflection spectroscopic measurement device includes a terahertz wave generation unit, an internal total reflection prism, a detection unit configured to detect the terahertz wave, an electric field vector measurement unit configured to measure an electric field vector of the terahertz wave, and an analysis unit configured to acquire information about an optical constant of the object to be measured. Proportions of S polarization component and P polarization component of the terahertz wave are constant. The analysis unit acquires the information about the optical constant on the basis of a ratio between S polarization component and P polarization component of the measured electric field vector when the object is not arranged on the total reflection surface and a ratio between S polarization component and P polarization component of the measured electric field vector when the object is arranged on the total reflection surface.
