A quantitative test of infrared optical constants

بررسی تاثیر شیوه خشک سازی بر خواص اپتیکی فیلم های نازک نانو ساختاری اکسید نیکل

The nanostructured nickel oxide thin films were prepared by dip coating sol – gel method. Three methods (drying with oven, IR and microwave) have used for drying the films. The effect of drying method on the optical, molecular, electrical, structural, and morphology properties of the films were studied by Uv-Visible spectrophotometry, Fourier Transform Infrared spectroscopy, Hall effect, X-ray ...

Gypsum Optical Constants in the Visible and Near-infrared: Real and Imagined

Introduction: Recent and on-going remote and in situ observations indicate that sulfates are present in significant abundances at various locations on Mars [1-5]. In addition, the scheduled Mars Reconnaissance Orbiter (MRO) will be equipped with an imaging spectrometer (CRISM) that will return hyperspectral data at higher spatial resolution [6] than the OMEGA instrument on the Mars Express Miss...

Evaluation of Reflection Optical Imaging Characteristics Using Fluorescence with Near Infrared Wavelength at Different Depths of Tissue Equivalent Phantom

Optical constants of crystalline WO3 deposited by magnetron sputtering

constants of crystalline WO 3 deposited by magnetron sputtering" (1999). Crystalline WO 3Ϫx is an infrared ͑IR͒ electrochromic material having possible applications in satellite thermal control and IR switches. Optical constants of electrochromic materials change upon ion intercalation, usually with H ϩ or Li ϩ. Of primary concern for device design are the optical constants in both the intercalat...

Estimating mineral abundances of clay and gypsum mixtures using radiative transfer models applied to visible-near infrared reflectance spectra

Quantitative mineral abundances of lab derived clay–gypsum mixtures were estimated using a revised Hapke VIS-NIR and Shkuratov radiative transfer model. Montmorillonite–gypsum mixtures were used to test the effectiveness of the model in distinguishing between subtle differences in minor absorption features that are diagnostic of mineralogy in the presence of strong H 2 O absorptions that are no...
