According to the result of examination , when using this spatial light modulator steer under a driving voltage of 2100 volt , and made the write light ’ s intensity in 4 . 3 w , the exposure time was 4 sec , in this case , the image can be clearly readout by the he - ne laser in intensity of 1 . 24 w 实验表明,该空间光调制器可以在2100v的电压下,使写入光强为4 . 3 w图像,经过4s的曝光写入器件,并由光强为1 . 24 w氦氖激光读出清晰的图像。
《 observation and nursing care during treatment of headache with hene laser intravascular radiation 》 abstract 48 patient with hypertensive or vascular headache were theated with low energy hene laser intravascular radiation . the result showed that ilib could relieve symptoms greatly , two courses of treatment would be more effective , and no obvious adverse reaction occurred 提要低能量氦氖激光血管内照射治疗高血压病头痛及血管神经性头痛48例，结果显示此法能较好地缓解症状，并且以治疗两个疗程( 10次)为佳，治疗过程中无明显不良反应。
Firstly , optical trigonometry measurement principle and wok principle of linear ccd are introduced , which are based on to design optical focusing and imagery system with he - ne laser instrument as illuminant . secondly , peripheral circuit of linear ccd is designed in theory and experiment . finally non - contact thickness measurement instrument is constructed , using ccd as photoelectric transformation element and microprocessor as the controller 本文首先介绍了光学三角法测量原理，并对线阵ccd的工作原理进行了研究，以此为基础采用氦氖激光器为光源，设计了光学聚焦及成像系统，对线阵ccd外围电路的设计进行了理论设计和实验研究，最后设计了以ccd为光电转换元件，以微处理器为控制核心的非接触式厚度测量仪及其系统。
It can also cure all sorts of gathering and no gathering inflammation , such as eyelid edge inflammation , seeping otitis media , central retina inflammation , gathering otitis media , chronic pharyngitis , oral ulcer , tongue pain , perleche , facial nerve palsy , bronchitis , rheumatoid arthritis , shoulder - joint - around inflammation , spot baldhead , belt sore , outside pudenda scratch and itch disease , foetus position abnormal etc . , all about 100 diseases Jh30型氦氖激光治疗仪，还可配合光导纤维输出激光，除作体表照射外，可用于腔洞组织及穴位的照射治疗。常规配置有一进一出光纤或一进二出光纤输出激光。专用与穴位照射的光纤有一进四出光纤，光纤输出端可配接穴位固定盘。
