In an optical system measuring sample characteristics, by reducing the amount of ambient absorbing gas or gases and moisture present in at least a portion of the illumination and detection paths experienced by vacuum ultraviolet (VUV) radiation used in the measurement process, the attenuation of such wavelength components can be reduced. Such reduction can be accomplished by a process without requiring the evacuation of all gases and moisture from the measurement system. In one embodiment, the reduction can be accomplished by displacing at least some of the absorbing gas(es) and moisture present in at least a portion of the measuring paths so as to reduce the attenuation of VUV radiation.

Radiation measurement system and method with synchronous high speed tracking laser based position measurement
ActiveUS20150116164A1Improve performanceMeasurement leads/probesMeasuring interference from external sourcesRF probeMeasurement point
An Antenna measurement system incorporating high speed tracking laser-based global positioning capture synchronized with radio frequency (RF) measurements. A high speed tracking laser is used for collecting RF probe position data synchronously with corresponding near-field RF measurements. The probe may be moved across an arbitrary surface surrounding or adjacent to a device under test (DUT); however, it is not necessary for the probe position to be perfectly coincident with the surface, or any of the discrete points which make up the surface. Here, the probe position is determined relative to a global positioning coordinate system which is defined by a set of monuments which are in known positions relative to the global positioning coordinate system, and not the DUT. Any difference between the actual position of the probe, in the global position coordinate system, and a given one of the discrete measuring points, in the global position coordinate system, on the surface surrounding or adjacent to the DUT can be accounted for during post processing, thus eliminating the need for advanced or intermittent calibration to achieve precise near-field measurements.

An analytical model simulates the propagation of radiation through a coated continuous web where layer thickness and refractive index, as variables, determine the speed and direction of transmitted radiation. The model predicts characteristics of transmitted radiation based on characteristics of incident radiation and initially assigned values for layer thicknesses. Coating thickness(s) are ascertained in a process whereby incident radiation of known characteristics is directed onto a coated web and thereafter, actual measurements of transmitted radiation are compared to predicted characteristics. Using a fitting algorithm, the assigned thickness(es) of the layer(s) of the model are adjusted and the process repeated until the actual and predicted values are within desired limits at which time, the assigned thickness(es) represent the measured calipers. Radiation measurements are obtained using terahertz time-domain spectroscopy apparatus that creates a continuous reference whereby a sample pulses' phase and amplitude can be tracked and corrected.
