Interpretation of reflection and transmission spectra for thin films: transmission

Applied Optics, 1995
The optical behavior of a thin film, that is, peak positions and intensities, is discussed for transmission under a thin-film approximation. The infrared transmission spectra of thin films, both standing films and those on dielectric substrates, are simulated for s and p polarization at various angles of incidence.

Transmission Spectra of Light to the Mammalian Retina

Photochemistry and Photobiology, 2000
A simple method has been developed to determine the optical properties of the anterior segment of the intact eye. This consists of a probe that is inserted into the posterior sclera and detects light passing through the anterior segment. The probe is connected to a charge-coupled device spectrophotometer via a fiber optic bundle. It was determined that

Submillimeter transmission spectra of Sr2Ca2Cu4Oy

International Journal of Infrared and Millimeter Waves, 1991
Abstract Transmission spectra of Sr 2 Ca 2 Cu 4 O y which is a part of high T c superconducting system Bi 2 Sr 2 Ca n−1 Cu n O z , and their temperature evolutions were investigated by monochromatic quasioptical submillimeter spectroscopy. Strong increase of high frequency conductivity in the range 80 to 350K was revealed.

Transmission spectra of artificial opals

Inorganic Materials, 2009
Transmission spectra of globular photon crystals with various globule diameters filled with ethyl alcohol and free of any filler are studied. It is found that, with the increase in the globule diameter, the spectral position of the stop band is displaced into the long-wave area of the spectrum.

Simplified interpretation of Martian transmission spectra

Journal of Quantitative Spectroscopy and Radiative Transfer, 1968
Abstract A highly simplified procedure for the interpretation of Kuiper's Martian and telluric transmission measurements in the 2 μ region is shown to lead to a Martian surface pressure estimate of about 5 ± 1 mbar.

Measurement of neutron spectra by the transmission method

Nuclear Instruments and Methods, 1968
Abstract Burke and Lowe2) described a method for the measurement of neutron spectrum and temperature of a beam of neutrons based on transmission through various thicknesses of 1/v absorbers. The analysis was done considering single collision phenomena.

Fast neutron spectra and transmission measurements

Acta Physica Hungarica, 1986
This article briefly describes a method of evaluating the neutron spectra from measured pulse-height distribution produced by recoil protons in scintillation detector and an algorithm for shielding calculation in subgroup approximation by Monte Carlo method.

Modeling the Transmission Spectra of WASP-31b

Proceedings of the International Astronomical Union, 2018
AbstractWasp-31b is a planet of 0.48 Jupiter masses and 1.55 Jupiter radii, with orbital period of 3.4-days around a metal-poor, late-F-type, V = 11.7 dwarf star. The planet has a large atmospheric scale height that makes it a good target for transmission spectroscopy.

The mid‐infrared transmission spectra of Antarctic ureilites

Meteoritics, 1993
Abstract— The mid‐infrared (4000–450 cm−1; 2.5–22.2 μm) transmission spectra of seven Antarctic ureilites and 10 Antarctic H‐5 ordinary chondrites are presented. The ureilite spectra show a number of absorption bands, the strongest of which is a wide, complex feature centered near 1000 cm−1 (10 μm) due to Si‐O stretching vibrations in silicates.

Correcting Infrared Spectra for Atmospheric Transmission

Publications of the Astronomical Society of the Pacific, 2007
Astronomical spectra taken with ground-based telescopes in the near-IR spectral region are affected by strong absorptions due to molecules in the Earth's atmosphere, particularly CO2 and H2O. These features need to be removed in order to reveal the true spectrum of the object being observed.
