Considering the problem of color distortion caused by the defogging algorithm based on dark channel prior, an improved algorithm was proposed to calculate the transmittance of all channels respectively. First, incident light frequency’s effect on the transmittance of various color channels was analyzed according to the Beer-Lambert’s Law, from which a proportion among various channel transmitta...

Instrumentation is described that has been constructed at the National Institute of Standards and Technology (NIST) for the measurement of regular re ̄ectance and transmittance over the 2±25 mm wavelength region. This includes both specialized accessories used with Fourier-transform infrared (FT-IR) spectrometers and laser-based systems for high optical density transmittance measurements. The FT...

Conclusion: This work has found that AU films have better transmittance than Ag and AI. The 120 , & Au films have -60% transmittance compared to 70% for ITO. Au films with transmittances reaching 80% were also obtained with a corresponding degradation in resistance. The most important aspect to note is that Au films may have promise as transparent contacts. The resistance and transmittance did ...

Transmittance of electromagnetic waves with normal incidence in one-dimensional plasma photonic crystals is studied numerically based on the invariant imbedding method. Wave transmittance as a function of wave frequency shows the appearance of forbidden band gaps, which are conspicuous in photonic crystals. We also demonstrate that the small modification of plasma photonic crystal leads to diff...

background: optical coherence tomography (oct) is a simple, high-resolution technique to quantify the thickness of retinal nerve fiber layer (rnfl) and macula volume, which provide an indirect measurement of axonal damage in multiple sclerosis (ms). this study aimed to evaluate oct finding in relapsing-remitting ms patients of the northwest of iran and compare them with a normal control group. ...

A multimode microcavity sensor based on a self-interference microring resonator is demonstrated experimentally. The proposed sensing method implemented by recording wide band transmission spectra that consist of multiple resonant modes. It different from previous dissipative scheme, which aims at measuring the depth changes single mode in microcavity. Here, combining mechanism and machine learn...

For the first time Rigorous Coupled Wave Analysis (RCWA) has been applied to the analysis of the transmittance spectra for the determination of critical dimension (CD) of phase-shift photomasks. The use of transmittance spectra proved to be instrumental in improving the sensitivity of the measurement to minor (sub-nanometer) changes in the width of the trench. We present a novel unique metrolog...

A series of experiments was performed to determine how the visual system computes the transmittance of inhomogeneous surfaces and media. Previous work (Anderson, B. L. (1999) Stereoscopic surface perception. Neuron, 26, 919-928; Anderson, B. L. (2003) The role of occlusion in the perception of depth, lightness, and opacity. Psychological Review, 110, 762-784) has suggested that the visual syste...

This paper reports a new type of transmitting mode electrochromic device that uses the high-contrast electrochromism of poly(3,4-ethylenedioxythiophene) (PEDOT) and operates at long-wavelength infrared (8-12 μm) . To maximize the transmittance contrast and transmittance contrast ratio of the device for thermal camouflage, we control the thickness of the thin PEDOT layer from 25 nm to 400 nm and...

We succeeded in causing transmittance self-oscillations of a novel self-oscillating polymer chain induced by the Belouzov-Zhabotinsky (BZ) reaction under constant conditions. The novel polymer chain was composed of a biocompatible and non-thermoresponsive poly-vinylpyrrolidone (PVP) main-chain, covalently-bonded to the ruthenium catalyst (Ru(bpy)3) of the BZ reaction. We investigated the influe...
