Acoustooptic digital filter.

چکیده
Digital filters have three components: (1) unit delays, (2) multipliers, and (3) adders. These components can be implemented by using (1) a Bragg cell as a tapped delay line, (2) optical multiplication using the Bragg cell transmittance, and (3) photodetectors. Multiplexing techniques are shown to increase geometrically the data handling capacity of such filters. An architecture for a 2-D digital filter using such techniques is presented.

متن کاملWavelength-Swept Fiber Laser with Frequency Shifted Feedback and Resonantly Swept Intra-Cavity Acoustooptic Tunable Filter
This paper concerns a wavelength-swept fiber laser (WSFL) incorporating frequency shifted feedback and an intracavity passband filter, in which the wavelength of the modeless output is linearly, continuously and repeatedly tuned (in time) over a given range by modulation of the filter peak wavelength and filter strength. We show both numerically and experimentally that amplifier noise plays a k...
متن کاملAll-Fiber Wavelength-Tunable Acoustooptic Switches Based on Intermodal Coupling in Fibers
In this paper, we demonstrate a novel all-fiber wavelength-tunable acoustooptic switch utilizing intermodal coupling in a two-mode fiber (TMF). Its all-fiber configuration consisting of a fiber acoustooptic tunable filter and a mode-selective coupler results in the low loss ( 2 dB) operation. The operating bandwidth 50 nm, the switching time of 40 sec, and the crosstalk of 20 dB were achieved. ...
متن کاملLow latency IIR digital filter design by using metaheuristic optimization algorithms
Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...
متن کاملAdaptive acoustooptic filter.
The design of optimum systems, in the classical sense, requires a priori some knowledge of the signals to be encountered. As a result, such systems perform poorly when the appropriate characteristics of the input signals are not known a priori sufficiently well or are timevarying. An adaptive processor has the ability to selfoptimize by continually monitoring its performance and updating its pa...
