crystaloptimizationss="para">— An achromatic quarter-wave film using one twisted-nematic liquid-crystal (TNLC) cell, a chromatic half-wave plate, and a chromatic quarter-wave plate is presented. The Jones matrix is used to calculate the optical properties of the system. An optimal algorithm ...
in refs19,20,22,23,24. A close inspection reveals that for arbitrary values of the achromatic phase shift θ, (33) is strictly positive, see Fig. 3. The only exception occurs when we set the achromatic phase shift into the quarter-wave plate configuration (θ = π/2), which ...
The H- and V-polarized photons, after impinging on the polarizing beamsplitter (PBS), propagated along the long and short arms of the interferometer, respectively, and were then retroreflected at the end mirrors, double passing the quarter-wave plates (QWPs) for the purpose of swapping their...
I’d be staying at their new home in Algiers Point—a free ferry ride across the river from the French Quarter. Before I even settled myself in the front seat of the faithful ole red truck she said, “Promise me you will not walk by yourself everywhere at all hours like you usually ...
Their effectiveness is related to ambient illumination; at least a quarter moon is required for older models, although current models are effective in overcast starlight (Tucker, 1984). Areas with low visual contrast are difficult to discriminate and, if ambient light goes below the goggle's ...
[1,2]. If the same load is applied during a hard impact, the period for stress wave prorogation becomes too short, and the response of the slab under the load is influenced by its local failure [2]. The probability of the punching or flexure-shear increases and there may be a ...
Because timing is the essence of comedy, that would be when it started to rain on the quarter million dollar laser system, destroying it. Bob no longer worked at $LASER_COMPANY two weeks later. MORAL: Of all the bystanders you could injure, DO NOT HURT THE SAFETY PERSON. ~fin~ Posted ...
A homemade fiber-based confocal microscope is used for performing the polarization-resolved PL spectroscopy. Polarizers and quarter wave plates are installed on the excitation and detection arms of the confocal microscope for polarization-selective excitation and PL detection. The PL emission is directed...
yielding reproductive output orders of magnitude lower and reproductive synchrony levels less than a quarter than that ofM. capitata. While mature oocytes were still present, the absence of mature sperm in the winter months suggests a possible cessation of spawning activity after October or early Nove...
(AQWP), which provides quarterwave retardance at more than one wavelength band and/or over a relatively broad wavelength band. Conventionally, AQWPs are fabricated by laminating two or more different waveplates together, e.g. a half-waveplate layer and a quarter-waveplate layer, of two ...
