Laser: In simple words, the Laser is a kind of light source that generally generates a very narrow and focused light beam. It generally produces a kind of radiation. The Laser is also known as light amplification by stimulated emission of radiation. ...
so the designer should perform a reality check with the lens manufacturer to ensure that there are no misunderstandings. It is better to have the customer specifically state whether the curve is convex or concave, rather than simply rely on the sign of the curvature term in the ...

What is gravitational waves (引力波)?Scientists have for the first time observed ripples in the fabric of space time (时空涟漪) called gravitational waves,arriving at the earth from a severely destructive event in the distant universe.It confirms a major prediction of Albert Einstein's 1915...

aA laser interferometer measurement system and an electronic differential level were used to measure machine linkage errors. Those errors include linear errors of feed mechanisms, straightness errors of guideways, angular errors of machine slides, out-of-squareness errors among machine axes, thermal expan...
aIn the system calibration the rod is set on the vertical conveyor controlled by laser interferometer and the digital level at a certain distance from the rod as illustrated in Fig. 3. The rod is moved step by step in vertical direction and the rod readings are observed with the instrument ...
