We also propose incoherent light treatment after the hologram is recorded in order to evaluate if the phase separation evolved correctly during hologram recording.
In this situation polymerization by incoherent light in the dark zones notably decreases the index modulation.
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 standard film will be produced in 10-100 [mu]m gauge, but BMS is aiming to be able to produce 5-7 [mu]m films (although this will have a reduced performance because of the limited depth of material
The Crystalsizer uses incoherent light
diffraction and is designed to measure both free flowing and cohesive dry powders over a range of 0.7 to 2,500 microns.
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.
Standard microscopes illuminate an entire sample at once from an incoherent light source, making the illumination spatially incoherent.
