地面无栅栏个人或集体用游泳池的保护元件.报警系统.第2部分:光束扫描探测系统的安全要求和试验方法 - Abstract : during the measurement of optical nonlinearities of sample in the thin film by z - scan technique , ablating makes a hole in the thin film if the incidental laser power is too high , that will produce the error to measurement results
文摘:用单光束扫描法研究薄膜材料的非线性光学性质时，如果入射样品的激光功率过大，将会烧蚀薄膜而产生孔洞，虽然其归一化透过率曲线类似于没有烧蚀的情况，但与样品的非线性光学性质无关，因而造成测量结果错误。 - Lc apparatus almost meet all the needs of space optical communication such as weight , size , power consume , life , cost , driving voltage , intergration of optics and electricity , programe , optically take ? over aperture , beam scanning , deflexional range and so on . switches , deflexional facilities and scanning equipments which made with lc have been used in the system of labor in space communication . the only bug of lc apparatus is that their answer speed only get microsecond rate or submicrosecond rate . but it is practical for them to be used in special beam capture , scan , deflexion controling which don ’ t concerned with code rate and code type
液晶器件几乎满足空间光通信的所有大的指标要求如重量、尺寸、功耗、寿命、成本、驱动电压、光电集成、可编程性、光学接收孔径、光束扫描和偏转范围等等。液晶光开关、光偏转器、光扫描器已经开始应用于光纤通信的实验系统中。液晶类器件应用于光通信的唯一重大缺陷,是其响应速度目前只能达到微秒级或亚微秒级,不过,在不涉及到码型码率的空间光束捕获、扫描、偏转、控制方面,液晶器件完全可能进入实用化。 - The results showed that the processing parameters ( such as laser power , the diameter of laser , scanning speed of laser beam , ratio of overlapping ) are important to acquire a perfect component . furthermore , in order to assure geometric properties ( accuracy , surface finish ) , the structure of the off - axial powder nozzle was improved to avoid the oxidation of the molten pool . the density metal test sample of rene95 high - temperature alloy was made by lsf through optimizing the processing parameters
本文对激光立体成形的工艺特性进行了深入系统的研究，发现如果要获得理想的成形效果，就必须对成形过程中的工艺参数进行精密控制，例如激光功率、激光光斑大小、光束扫描速度、搭接率等；同时为了保证成形件有较高的尺寸精度和表面质量，必须对成形零件的氧化问题进行控制，通过改进侧向送粉喷嘴的结构设计，成形件的表面氧化问题得到适度控制。
