Luminescent optical fibers in sensing, Snitzer in the early 1960s of the use of an optical fiber geometry for lasers and optical amplification, employing 300 μm core diameter neodymium doped fiber. Subsequent development of this concept has been the major reason for the production of a range of different types of optical fiber, dopebotany 发表于 2025-3-25 12:56:41
Liquid crystals in optical fiber sensors,n these exciting areas. Although the primary applications for each of these technologies are rather disparate, with liquid crystals used primarily for display devices and optical fibers for telecommunications purposes, they have in common one aspect — light. Optical fibers serve to transport light fMOAN 发表于 2025-3-25 16:49:29

M. R. Shahriariway of the index or the lists of diseases given under the different hosts in Chapter 4. On page 533 you will find a list of headings under which diseases are grouped and described, from Anthracnose to Wilts. In the Host section the key word, for example, rot or blight, is given in capital and small突变 发表于 2025-3-26 12:19:02
