As telescopes used ingravitational wave detectors have to be designed for imaging truncated Gaussian beams in contrast to the more usual incoherent light sources concepts derived from geometrical optics might have to be modified and cannot necessarily be used for trading-off telescope architectures.
In FDTD simulations the incorporation of an incoherent light source for different electromagnetic applications is possible [16,17] however the simulations of solar cells/opto-electronic devices in the time domain may not be as accurate as in the frequency domain.
What we have shown is that you don't need lasers - everybody else was doing this with lasers, and we showed you can do it with incoherent light from a lamp or the Sun - natural light," Prof Silberberg told BBC News.
By combining light from the incoherent light source with the light from the coherent light source, the overall power level of the coherent light source in the combined light beam may be reduced while still perceiving a crisp, clear image," writes the inventor, Brett Bilbrey.
It will only require laser exposure followed by curing with incoherent light.
The Crystalsizer uses incoherent light diffraction and is designed to measure both free flowing and cohesive dry powders over a range of 0.
In a standard reflection optical microscope, the sample is uniformly illuminated through the objective lens by an incoherent light source such as a filament lamp.
Photodynamic therapy of acne vulgaris with topical d-aminolevulinic acid and incoherent light in Japanese patients.
Under the program, any physician who has previously purchased an ESC Photoderm-VL device can now trade in this nonselective, incoherent light source device and receive a substantial discount on the latest, most effective system for the treatment of leg veins.
Here I propose new thermodynamic concepts for frequency conversion of partially incoherent light aiming to overcome the SQ limit for single junction PVs.
