Aspherical Lens. A type of optical lens in which the surface curves are not portions of a sphere. Compared to a traditional non-aspheric lens, the more complex shape of aspherical lenses allows light rays to more precisely converge onto a single focal point, reducing various types of optical ...
In his discussion of Leonardo da Vinci’s unpublished journals that grapple with the notion of the possible inversion of the image within the eye, Lindberg says with subtle sarcasm, “one of Leonardo’s major preoccupations was with the actual path of rays through the eye. His chief concern ...
Designing a lens can be compared to playing chess. In chess a player tries to trap his opponent’s king in a series of moves. In creating a lens a lens designer attempts to “trap” light by forcing all the rays arising from a single point in the subject to focus on a single point ...
The designer translated Liu Yong's "angry waves rolling frost and snow" into the "image" of space, and used two curved waves in the reception area to create an exhilarating feeling for guests who first entered the space, elevating the tone of this cloud space. 门廊的尽头正对着远处的钱塘江...
As the earth proceeds in its orbit from this point, the inclination of the north pole toward the sun becomes less and less, until on the 23d of September the sun is directly over the equator. The north pole now begins to point away from the sun. On December 21 the direct rays of th...
These then, limiting ourselves to select specimens, are the principal participants in this musical evening: the Scops-owl, with his languorous solos; the Toad, that tinkler of sonatas; the Italian Cricket, who scrapes the first string of a violin; and the Green Grasshopper, who seems to bea...
After all, GR explains how objects cause curvature to the fabric of space. If our two superimposed states cause this to be curved in different ways, couldn’t we measure that and the sudden effects that would have on space-time? The issue here is scale. Small objects are easy to superimp...
01、Bad luck refers to things happening in ways you do not want. An event in itself is not bad luck, but it could be bad luckto someone. My losing money is bad luck for me, but it may be someone else's good luck (if they dishonestly keep the money). ...
Another pair, known as the first and second principal points, will now be defined. Fig. 11. Principal planes of a complex lens system, a. Paths of paraxial rays from infinity to F′ and F. b. Lens system is replaced by a black box in which two planes, found by the intersection of...
Interaction of neutrons and gamma rays in the multi-layer material [94]. Polyimide resin (PI) has a very stable aromatic heterocyclic structure, which made it exhibit incomparable thermal (decomposition temperature 600 °C, long-term use at 330 °C) and low-temperature resistance that other po...
