Neither van Heel nor Hopkins and Kapany made bundles that could carry light far, but their reports began the fiber optics revolution. The crucial innova- tion was made by van Heel, stimulated by a conversation with the American opti- cal physicist Brian O’Brien (Figure 1-5). All earlier fibers were bare, with total internal reflection at a glass-air interface. Van Heel covered a bare fiber of glass or plastic with a transparent cladding of lower refractive index. This protected the total-reflection surface from contamination and greatly reduced crosstalk between fibers. The next key step was development of glass-clad fibers by Lawrence Curtiss (Figure 1-6), then an undergraduate at the University of Michi- gan working part-time on a project with physician Basil Hirschowitz (Figure 1-7) and physicist C. Wilbur Peters to develop an endoscope to examine the inside of the stomach (Figure 1-8). Will Hicks, then working at the American Optical Co., 4 CHAPTER 1 — THE ORIGINS OF FIBER OPTIC COMMUNICATIONS

keberadaan tangga pada saat kita melihat, belum tentu tangga tersebut berada pada posisi sebenarnya. Hal ini terjadi karena adanya pembiasaan cahaya, dimana menurut ilmu fisika tentang cahaya, jika cahaya jatuh pada medium yang berbeda indeks biasnya, cahaya tersebut akan dibiaskan dan sudut datang dari sinar laser yang dikirimkan pada serat optik dapat memungkinkan untuk mengatur seberapa efisiensi sinar laser tersebut sampai pada tujuan. Gelombang cahaya di arahkan melalui inti dari fiber optic tersebut, sama seperti gelombang radio yang diarahkan melalui kabel koaksial. Sinar laser pada serat optik di arahkan hingga ke ujung dari fiber optic tersebut dengan memanfaatkan prinsip dari pemantulan cahaya di dalam inti serat optik.

Development Of Fiber Optic Sensor For Water Level Measurement Using Fiber Optic Application.

Development Of Fiber Optic Sensor For Water Level Measurement Using Fiber Optic Application.

There are three main parts in a model of simple fiber optic which are known as source-user pair, transmitter and receiver. In fiber optics, a source of light is used to emit electromagnetic radiation in order to perform a specific task, whether detecting faults, breaks or characterizing link-loss. While, the transmitter is transmitted the source to the receiver as well.

Application Of Microfiber Sensor For Determining Olive Oil Concentration.

Application Of Microfiber Sensor For Determining Olive Oil Concentration.

In the past 50 years, fiber-optical sensing has been one of the most successful and powerful applications of both fiber optics and sensing technology. Recently, along with the rapid progress in micro/nanotechnology and increasing demands on optical sensors with higher performances and versatilities, spatial miniaturization has been one of the current trends of fiber-optic sensors. It is obvious that, reducing the size of a sensing structure is usually an essential step to bestow the sensor with faster response, higher sensitivity, low power consumption and better spatial resolution, and an optical microfiber is one of the best candidates for this purpose.

Effect Of Nanoclay Loading On Natural Fiber Composite.

Effect Of Nanoclay Loading On Natural Fiber Composite.

Kenaf fiber reinforced composite is prepared using the internal mixing technique in order to analyse the effect of nanoclay loading in the composite and improve the tensile properties of the conventional kenaf fiber reinforced. Composite is prepared by mixing constant composition of matrices PP/PLA and kenaf fibers at 97 wt%, 3 wt% and 40 wt% respectively but with different percentage of 0 wt%, 1 wt%, 3 wt% and 5 wt% nanoclay loading. Then, the hot press is done to produce the composite that undergoes tensile test. Result for tensile test shows increasing of nanoclay loading in the composite cause the decreasing tensile properties. However, 1 wt% nanoclay in the composite increases the Young Modulus of the composite. This is supported by the liquid immersion test results where the specimen with 1 wt% nanoclay has better result compared to other specimen that does not have nanoclay and specimens with 3 wt% and 5 wt% nanoclay. Based on the result, specimen KeN 1%-PP/PLA is the best specimen with average tensile strength of 30.59 MPa, average Young Modulus of 2.32 GPa while the average value liquid immersion is 1.78%.

Effect of Compatibilizer and Bamboo Fibe

Effect of Compatibilizer and Bamboo Fibe

An investigation was carried out regarding the effect of compatibilizer (maleic anhydride grafted PP) and bamboo fiber content on the mechanical properties of polypropylene/bamboo fiber composites according to a two-level factorial central composite design. Composites were prepared in a co-rotating twin-screw extruder and specimens were injection molded. Effect of the variables on mechanical properties has been assessed through flexural modulus and strength, tensile strength, elongation at break and impact strength. With the exception of impact strength, all properties assessed showed to be significantly affected by the variable bamboo fiber content: positively in the case of tensile strength, flexural strength and modulus; and negatively in the case of elongation and energy at break. Compatibilizer content showed significant positive effect on all properties, except impact strength and flexural modulus. The only variable that seemed to affect impact strength was the interaction between bamboo fiber and compatibilizer content. This interaction effect also seemed to be significant for the tensile, but not for the flexural properties. Scanning electron microscopy revealed the adhesion achieved between the nonpolar hydrophobic polymer matrix and the polar hydrophilic bamboo fibers when using the compatibilizer PPgMA.

PENGARUH APLIKASI FIBER BRAIDED POLYETHYLENE TERHADAP KEKUATAN TEKAN RESIN KOMPOSIT NANOFIL Pengaruh Aplikasi Fiber Braided Polyethylene Terhadap Kekuatan Tekan Resin Komposit Nanofil.

Nanofilled composite resin is known has lower compressive strength than microhybrid and microfilled composite resin. The compressive strength has an important role for mastication process. Fatigue fracture is a factor which ha s been considered the cause of restoration failure. An altenative material to strengthen dental resins is fiber. Braided polyethylene fiber has been commonly used in dentistry because it has good aesthethic, strengthen composite restorative materials, increases strength and modulus of elasticity. The purpose of this research is to understand the effect of placing braided polyethylene fiber on compressive strength of nanofilled composite resin. The research finding wa s initiated by making samples for control and experimental group. It was then be mea sured for compressive strength. Samples were prepared in a costumized cylinder acrylic mould of 4 mm diameter and 8 mm height. Control group were made of nanofilled composite resin without braided polyethylene fiber, and experimental group were made of nanofilled composite resin with braided polyethylene fiber as reinforcing material. Samples were exposed by light curing unit for 20 seconds. All specimens were immersed in aquades and incubated at 37°C for 24 hours. The compressive strength test wa s determined by using Universal Testing Machine at 1 mm/min crosshead speed. The results were statistically analyzed by using independent sample t-test. The statistic results showed p= 0.504 (p> 0.05). The conclusion of the research showed that braided polyethylene fiber has no effect on compressive strength of nanofilled composite resin.
