Achromatic design in the illumination system for a mini projector with LED light source.
We provide a novel achromatic design in the illumination system for a mini projector with an LED light source. The lateral color aberration at the corners of the DMD active area can be reduced to 0.48 μm by our compact ATIR prism. The total prism size is 4091 mm(3). The spot sizes at the corner and the edge are also controlled under 198 μm. Moreover, we use a light pipe for color uniformity at ...
متن کاملDesign of axisymmetrical tailored concentrators for LED light source applications
In our contribution we present a solution to an important question in the design of a LED-based illumination engine for projection systems: the collimation of the LED light. We tested the principle in the modification of a common device in non-imaging optics, the compound Parabolic Concentrator. This CPC-like achieves a collection of 72% (ideal reflective coating presumed). This CPC-like was ta...
متن کاملMini N2-Raman Lidar Onboard Ultra-Light Aircraft for Aerosol Measurements: Demonstration and Extrapolation
Few airborne aerosol research experiments have deployed N2-Raman Lidar despite its capability to retrieve aerosol optical properties without ambiguity. Here, we show the high scientific potential of this instrument when used with specific flight plans. Our demonstration is based on (i) a field-experiment conducted in June 2015 in southern France, involving a N2-Raman Lidar embedded on an ultra-...
متن کاملHydrogen Peroxide Photolysis with Different Uv Light Sources including a New Uv-led Light Source
Hydrogen peroxide 0.1% was photolyzed using 17W low pressure mercury arc lamp and 125 W high pressure mercury arc lamp. The decomposition kinetics was followed through the pseudofirst order kinetics and different conditions of temperature and pH were explored. H2O2 0.1% was also photolyzed at 360 nm through a new UV-LED 3W light source using a flow reactor. The kinetics rate constant achieved w...
