An Anti-Reflection Coating for Silicon Optics at Terahertz Frequencies
A method for reducing the reflections from silicon optics at terahertz frequencies has been investigated. In this study, we used thin films of parylene as an anti-reflection (AR) layer for silicon optics and show low-loss behavior well above 1 THz. Transmittance spectra are acquired on double-sided-parylene-coated, high-resistivity, single-crystal silicon etalons between 0.45 THz and 2.8 THz. M...
متن کاملReturn-path, multiple-principal-angle, internal-reflection ellipsometer for measuring IR optical properties of aqueous solutions.
A retroreflection (return-path) spectroscopic ellipsometer without a wave plate is described that uses an IR-transparent high-refractive-index hemicylindrical semiconductor substrate to measure the optical properties of aqueous solutions from multiple principal angles and multiple principal azimuths of attenuated internal reflection (AIR) at the semiconductor-solution interface. The pseudo-Brew...
متن کاملNoncontact Terahertz Paintmeter for Real-Time Two-Dimensional Cross-Section Imaging of Paint Film Thickness
Non-contact, remote monitoring of thickness and drying progress of a paint film is required in fields of non-destructive testing and evaluation. For rapid image acquisition of 2D cross-section in paint film, we propose a terahertz (THz) paintmeter based on real-time 2D THz tomography, which is achieved by a combination of electro-optical time-to-space conversion and line focusing of a THz beam ...
متن کاملTerahertz paintmeter for noncontact monitoring of thickness and drying progress in paint film.
We propose a paintmeter for noncontact and remote monitoring of the thickness and drying progress of a paint film based on the time-of-flight measurement of the echo signal of a terahertz (THz) electromagnetic pulse. The proposed method is effectively applied to two-dimensional mapping of the painting thickness distribution for single-layer and multilayer paint films. Furthermore, adequate para...
