Sentence examples for minimum Fresnel losses from inspiring English sources

The simulation and calculation results indicated that the present freeform lens could enhance the illumination uniformity greatly and realize minimum Fresnel losses as low as 7.67%.

In this study, we demonstrated a double freeform-surface lens to realize uniform illumination and minimum Fresnel losses for light-emitting diode (LED).

Monte Carlo ray-tracing simulation and Fresnel losses calculation were conducted to validate the present freeform lens.

Diffraction efficiency of holographic gratings, taking Fresnel losses into account, can be calculated accordingly, which is defined as the ratio between intensities of the first-order diffracted beam and the incident beam after passing through the sample.

The total injection losses plus Fresnel losses are thus estimated to be 29% and 33% for the two fiber lengths L = 0.5 mand L = 1.5 m.

We thus estimated the injected energy by assuming, at low power and before the appearance of the nonlinear effects, that the only losses are the injection losses and the Fresnel losses onto the glass windows.

Fresnel losses limit the transmission efficiency of the silicon filter to approximately 50%.

The current efficiency of these glass arrays does not leave much room for improvement, except to possibly modify the tip shape and apply an anti-reflection layer to the tip surfaces to reduce Fresnel losses.

Antireflective coatings will eliminate the input and output Fresnel losses, while better in-coupling via lenses to collimate or focus the light into the effective aperture of the shank will reduce the backplane and base losses; note that the use of single-mode coupling fibers would in principle allow better control over the input beam properties.

Earthquake related material loss was divided into three levels of none to minimum loss, moderate loss, and severe loss.

This paper presents a novel hybrid Fresnel-based concentrator with improved uniformity irradiance distribution on the solar cell without using secondary optical element (SOE) in the concentrator photovoltaic (CPV) system to overcome the Fresnel loss and to increase the solar cell conversion efficiency.
