Through a set of flat mirrors to replace the parabolic trough system of curved mirrors focus, adjust the tilt angle of the control plane mirror, reflect sunlight into the tube, in order to simplify the system, generally use water or steam as the heat-absorbing medium. Relatively low cost, ...

By way of example, the following procedure can be followed in order to determine the input mode base of the MPLC, when the assumed input beam is single-mode: define an assumed input mode, the closest possible mode to the input beam mode that will actually be used, construct a family ...
The numerical results show that the wavefront of the reflected wave can be manipulated over a wide frequency range; and the gradient design of the unit cells can suppress the parasitic reflection. The present work is relevant to the practical design of novel acoustic devices....
light beam with the first polygon mirror across a first set of pattern mirrors, producing a second light beam from a second laser and directing the second light beam onto a second polygon mirror, scanning the second light beam with the second polygon across a second set of pattern mirrors. ...

which combines the effects of contaminants (mainly Zn according to this study) and potential stressful air microclimatic conditions (e.g., low relative air humidity, high temperature, and UV level). Microbial activity and taxonomic diversity of the phylloplane could be considered as an additional ...
Filippo Brunelleschi, considered the founding father of Renaissance architecture, used mirrors and geometry to generate 3D drawings with perfect linear perspective. Leonardo da Vinci meticulously studied physics to create modern technical drawings of complex systems. Frank Gehry, dubbed by Vanity Fair...

However, practical lenses, mirrors, and camera systems introduce aberrations that cause the image resolution to vary over the image plane. One such well known aberration is astigmatism. Astigmatism is defined as the presence of separate focal lengths, along the principal axis, for rays of light ...
