A 1 cm long, low-finesse fiber-optic cavity was used as a transducer for the vibrations of the soundboard of an acoustic guitar and of a violin. The reflected light is detected and then amplified and recorded using conventional audio instrumentation. The fiber-optic pickup is found to have a high response range in both amplitude (up to 100 microm displacement) and audio frequency (DC to 20 kHz)...

In this paper, three ring networks made up of fiberribbon point-to-point links are presented. The first network is a control-channel based network in which one fiber in each link joins with others to form a controlchannel ring. This ring improves performance of the network by sending medium access control information immediately before the data transmissions. High throughputs can be achieved in...

Fiber-optic links are attractive for transmitting microwave/millimeter wave signals for applications such as radar, imaging and astronomy. However, current fiber-optic links that employs intensity modulation and direct detection suffer from limited spurious free dynamic range (SFDR). For solution, a new coherent fiber-optic link using linear phase modulation/demodulation has been proposed. The ...

The retinofugal pathway is a useful model for axon guidance because fibers from each eye project to targets on both sides of the brain. Studies using static and real time analyses in mice at E15-17 demonstrated that uncrossed axons from ventrotemporal retina diverge from crossed axons in the optic chiasm, where specialized resident cells may direct divergence. Other studies, however, suggest th...

Fiber-optic technology can be considered our savior for meeting our ever increasing needs because of it’s potentially limitless capabilities like huge bandwidth, low signal attenuation, minimal power requirement and low cost. DWDM is a technology that enables multiple wavelengths to be multiplexed onto one single fiber thereby creating many virtual fibers each capable of carrying a different si...

In this paper, we introduced a new fiber-optic temperature sensor with white light interferometric principle based on Fabry-Perot, which is capable of providing measurement for the temperature of greenhouse. The signal processing of system is that the optical signal wavelength is modulated in the Fabry-Perot cavity and is demodulated during the optical-electricity transform. Compared with a com...
