In addition to protecting vehicle occupants, POF is being used for pedestrian-protection systems. Since the bandwidth-distance product required is smaller, one can use large core fibers such as the plastic optical fiber (POF) and polymer cladded silica (PCS) fiber. The transmission signal changes when a surface- treated zone on the fiber is bent. If you look closely at a single optical fiber, you will see that it has the following parts: Advertisement . [6]International Journal of Scientific & Engineering Research, Volume 4, Issue 7, July-2013 209From this study on use of optical fibers in automobiles we conclude that Photonic technologies are superior to electronic solutions in terms of data rates, bandwidth, reliability, and robustness. Since the bandwidth-distance product required is smaller, one can use large core fibers such as the plastic optical fiber (POF) and polymer cladded silica (PCS) fiber. Far too many people to mention individually have assisted in so many ways. The major application areas of optical sensors are driver assistance systems and traffic monitoring systems. in Communication Systems from Guru Nanak Dev University, Amritsar in 2011.
Since the bandwidth-distance product required is smaller, one can use large core fibers such as the plastic optical fiber (POF) and polymer cladded silica (PCS) fiber. The spatial resolution is achieved by incorporating several fiber strands in parallel and using numerical signal analysis of the treated zones.
Far too many people to mention individually have assisted in so many ways.
Increasing demands regarding temperature performance, transmission losses, and bandwidth have pushed the current limits of the POF fiber, and the automotive industry is now moving towards an optical domain.of the cost of their pure silica counterparts .And it's not just navigation and entertainment functions that can exploit POF.Fiber optic transceivers (FOT) based on lead frame and plastic molding technologies for large core plastic optical fiber (POF) and polymer clad silica (PCS) fiber systems. Many manufacturers use fiber optics to connect all these devices.
This is ironic, seeing fiber offers end users access to data at the speed of light.
Seat- occupancy recognition could also be used to lower theFIG: 5 the well-known phenomenon of the "evanescent field" within an optical fiber can be used as a tactile sensor. They decay instead, exponentially within the cladding.
1).Plastic optical fiber can also be used for seat-occupancy recognition, resulting in cost reduction as well as increased safety. The transmitter module contains a VCSEL light source, an electronic driver chip, and passive electronic components.
For higher data rates up to the Gb/s range, a GaAs metal-semiconductor-metal (MSM) photo detector is used in the receiver module. This shift can be detected with very high sensitivity, allowing the motion of a window to be stopped if an object is in its path. Eye diagrams are wide open for all ambient conditions. It has taken many years for fiber optics to be used to their full potential for telecommunication services.
Fiber optics are also used to connect airbags and other safety devices. A sensor in the seat identifies whether the seat is occupied. [3]International Journal of Scientific & Engineering Research, Volume 4, Issue 7, July-2013 207FIG: 2 Transmitter and receiver components for the infotainment system in automobiles. In every sense, none of this work would have been possible without him. For my Fiber Optic Fairy Wings, I used a much simpler, and slightly jankier, method. Many European car manufacturers have already adopted the MOST system. Polymer cladded silica (PCS) fiber is under consideration to overcome the current operating temperature limitations.
The standard values of these parameters are given in Table 1.FIG: 3 Sensors using plastic optical fiber embedded within the framework of an automobile can be used to provide pedestrian protection.
Optical fiber transmission has revolutionized networking and communication systems. Some fiber optics make use of this light degradation, allowing a little light to escape through the cladding along the length of the fibers, thus creating an even glow that looks a bit like a neon tube. Well, it is a simple task once you’ve done it several times!! The core diameters of these fibers are normally 0.2mm to 1mm [3]. They all have sincere gratitude and thanks to several anonymous publishers of various journals and research papers for their help .I also owe a huge debt of gratitude to our friends who were instrumental in the success. The MOST and IDB1394 standards are an example for automotive infotainment systems. BMW has developed a POF optical network for internal use operating at 10 Mbit/s-a star network that is used to communicate with the air-bag sensors. He has been instrumental in ensuring academic, and moral well being ever since.
The basic principle behind the active pedestrian protection systems is a cladding surface treatment of the fiber at discrete zones along the fiber. Polymer optical fibers consist of a polymer core and a lower index polymer cladding. Add Tip Ask Question Comment Download. European Union directive 2003/102 mandates pedestrian protection in every new car manufactured from 2005 on, either by passive or active methods.
