Figure I-4-3 (b) shows the working principle of the cable. When a beam of light enters at one end of the transparent fiber, the light is totally reflected internally and is trapped within the rod. (b) (a) Figure I-4-3: (a) Fiber-optic cable, used to transmit a modulated laser...
the recent advances of short-pulse laser–induced breakdown effects on CCDs are reviewed. The basic structure and working principle of a CCD are introduced. The damage phenomenon and mechanism of different types of lasers on CCDs are clarified. The relationship between laser parameters (i.e., ...
As with any laser, a fiber laser uses the principle of stimulated emission. The majority of fiber lasers are made from a concatenation of fiber-coupled components. The fibers associated with the various components are called “passive fibers”. Passive fibers have no amplification properties. The ...
Micro-structures are widely utilized in various fields such as optical, medical, defense, and aerospace. The accuracy and performance of micro-structures d
(a) Structure diagram; (b) schematic diagram of the working principle 中国科学院西安光学精密机械研究所于2016年采用长磁聚焦系统提高漂移管动态空间分辨率, 解决了阴极电压和漂移距离等对系统时间放大倍数的影响等技术问题, 并于2018年研制了多碱阴极可见光响应的长磁聚焦漂移管分幅相机, 其静态空间分辨率为20...
Characteristic grating (line separation and depth) must be in the submicron scale, since the basic underlying physical principle is the reduction of vortex-line energy, being their typical dimensions in the range of tens or few hundreds of nanometers. More recently, the advent of powerful ...
In principle, a great variety of mechanisms in the adapter are suitable to transmit to the output side the radiation supplied to the input side. For ophthalmic procedures, the adapter will be conveniently designed in the manner of a contact glass, so that the beam path comprises, at least in...
The "Normin" reading display menu 43 choice of the full spindle check menu shown in FIG. 6 results in the display of FIG. 9. The word "Normin" refers to the Normin principle of taking two reading of "NORMal reading" at 0° and an "INverted reading" at 180°. The two readings of...
Principle of operation First, the light enters into the 50/50 coupler from Port 1 before being split equally via Port 2 and 3. These two counterpropagating beams recombine in the loop, with PMF causes the light travels at both fast and slow axis to create a phase difference. Hence, when...
In principle, the laser welding takes advantage of conversion of light energy of the laser to thermal energy. So the welding property is influenced by condition of the laser welding strikingly. Generally, quantity of surface heat energy that the laser-absorptive workpiece accepts from the laser ...
