Optical fiber process tomography ( ofpt ) is a new technology in the field of optical fiber sensor ( ofs ). the probe of ofpt is small, safe, free of electromagnetic interference and has high sensitivity in low - density medium case same as ofs, more important and different is that it can detect the medium distribution and contents of the cross - section to be investigated simultaneously, which makes ofpt show potential and extensive applications in petroleum, chemical, energy, medicine, food and sanitation fields to control product quality, realize safe production and reduce the cost
光纖過程層析成像是光纖傳感領域的一門新型技術,具有光纖傳感器的測量低濃度物質解析度高、體積小、抗電磁干擾以及可以進行分散式測量的共同優點和可以同時測量物質截面內部結構的獨特優點,在多相流動廣泛存在的石油、化工、能源等工業部門和醫療、衛生、食品等領域具有廣泛的應用前景,對監控產品質量、降低成本以及保證生產安全具有非常重要的意義。 -
Chapter 3 : we find a family of solutions of the paraxial wave equation that represents ultrashort pulsed light beams propagation in free space. these pulsed beams have an arbitrary temporal form and a nearly elegant hermite - gaussian cross section, which pulsed beams we call the ultralshort pulsed elegant hermite - gaussian beams
