Terahertz imaging technology is one of the candidate technologies for medical imaging. In particular, continuous terahertz reflection and attenuated total are expected to achieve rapid intraoperative imaging, which hot research topic at present. order realize multi-dimensional high-quality detection sample, it necessary study common optical path reflection/attenuated dual-mode system based on p...

acetylation is a chemical modification of wood to enhance its properties. ir-spectroscopy is a useful technique for proofing chemical bondings in wood and the at-tenuated total reflection (atr) infrared spectroscopy technique was applied as an eas-ier technique over other ir-spectroscopies. in this research, different degrees of acetyla-tion, weight percentage gains (wpgs) in beech and pine min...

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...

Capabilities of the attenuated total reflection (ATR) at THz wavelengths for increased sub-surface depth characterisation (bio-)materials are presented. The penetration a evanescent wave in biological samples is dependent on wavelength and temperature can reach 0.1–0.5 mm depth, due to strong refractive index change ∼0.4 ice-water transition; this quite significant important when studying sampl...
