Attenuated internal reflection terahertz imaging.

We present a terahertz (THz) imaging technique based on attenuated internal reflection, which is ideally suited for the analysis of liquid and biological samples. Inserted in a THz time-domain system, and using a high-resistivity low loss silicon prism to couple the THz wave into the sample, the detection scheme is based on the relative differential spectral phase of two orthogonal polarization...

Single-reflection attenuated total reflection of organic monolayers on silicon.

Attenuated total re ection (ATR) spectroscopy, a wellknown surface technique, is frequently used for examining very thin Ž lms on substrates. However, when it comes to examining thin Ž lms on silicon substrates, the high refractive index of the substrates seems to preclude ATR analysis. This paper demonstrates that extraordinary sensitivity can be achieved by using ATR to analyze monolayers on...

Detection of Ni2+ by a dimethylglyoxime probe using attenuated total-reflection infrared spectroscopy.

A new analytical approach for the detection of Ni2+ utilizing an attenuated total reflection (ATR) technique is discussed in this paper. Nickel detection was accomplished on a silicon ATR parallelogram crystal uniformly coated by a ca. 1.5-microm Nafion film embedded with dimethylglyoxime (DMG) probe molecules. The detection of Ni2+ is based on the appearance of a unique infrared absorption pea...

Blood glucose measurement by using hollow optical fiber-based attenuated total reflection probe.

A noninvasive glucose monitoring system based on mid-infrared, attenuated total reflection spectroscopy using a hollow optical fiber probe is developed. Owing to the flexible fiber probe, measurement of oral mucosa, where blood capillaries are near the skin surface, is possible. Blood glucose levels are measured by detecting the peak intensity of glucose absorption bands, and the experimental r...

Attenuated total reflection Fourier transform infrared spectra of faceted diamonds.

Attenuated total reflection Fourier transform infrared (ATR FT-IR) spectroscopy has been employed for characterization of faceted diamonds. ATR spectra of round brilliant cut natural diamonds of approximately 0.1 ct were observed with excellent spectral quality. The mirror-flat spectrum of the table facet enables a good contact to the ATR crystal with a minimal applied pressure. The observed AT...
