Photonic sensors, signal processors and communication technologies have emerged as viable alternatives to electronics. Fiber optic sensors which can readily be integrated with smart materials and structures offer an immense potential in the realization of intelligent systems. This paper presents an overview of different types of fiber optic sensors and their application to smart structures.

The propagation of the soliton pattern through optical fiber with weakly disordered dispersion coefficient is considered. Solitons perturbed by this disorder radiate and, as a consequence, decay. The average radiation profile is found. Emergence of a long-range intrachannel interaction between the solitons (mediated by this radiation) is reported. We show that soliton in a multisoliton pattern ...

The current paper describes the design of Fiber Optics Links for BTeV’s Pixel Detector readout. BTeV pixel detectors chips will be located as close as 6mm from the accelerator’s beam into the vacuum pipe. The readout electronics will be located at about 6cm from the beam, imposing strong constrains regarding radiation, mass, power dissipation, and size. The current development is the first prot...

Since their invention in the thirteenth century, Fibonacci sequences have intrigued mathematicians. As well as modeling the population patterns of overly energetic rabbits, however, they have sparked developments in more serious mathematics. For example, generalized Fibonacci sequences crop up in all manner of situations, from fiber optic networks [3] to computer algorithms [1] to probability t...

Free-Space Optics (FSO), also known as fiber-free or fiberless optics, is an emerging technology that transports data via laser technology. It is a line-of-sight technology that currently enables optical transmission up to 2.5 Gbps of data, voice and video though the air, allowing optical connectivity without deploying fiber-optic cable or securing spectrum licenses. It is moving closer to bein...

A fiber-optic based flow cytometry platform was designed to build a portable and robust instrument for space applications. At the core of the Microflow1 is a unique fiber-optic flow cell fitted to a fluidic system and fiber coupled to the source and detection channels. A Microflow1 engineering unit was first tested and benchmarked against a commercial flow cytometer as a reference in a standard...

Fiber optic assemblies have been used on spaceflight missions for many years as an enabling technology for routing, transmitting, and detecting optical signals. Due to the overwhelming success of NASA in implementing fiber optic assemblies on spaceflight science-based instruments, system scientists increasingly request fibers that perform in extreme environments while still maintaining very hig...
