There are two types of the acoustooptic filters – collinear and non-collinear filters – depending on geometry of acoustooptic interaction. Here we consider only non-collinear filters based on the TeO2 single crystal.

    Due to advantages such as a large angular aperture, high diffraction efficiency, as well as it having a fast, electronically-tuning property with a wide spectral range, the acousto-optic tunable filter (AOTF) has been widely used in biomedical, hyperspectral imaging and spectrum analysis [1–8].The AOTF is mainly composed of an acousto-optic medium and piezoelectric transducer. 36 works Search for books with subject Acoustooptical devices.

Uniform response high resolution tunable optical filtering using a grating-assisted acousto-optic device David Bitauld, Isabelle Zaquine, Alain Maruani. In an acousto-optic tunable filter, a piezoelectric transducer bonded to a crystal of tellurium dioxide or quartz generates high-frequency acoustical compression waves that alter the refractive index of the crystal in a periodic pattern.

Author. This article describes an imaging spectrometer developed for remote sensing applications. The instrument consists of an acousto-optic tunable filter (AOTF), a high sensitive charged coupled device camera and optic lens.

The selected AOTF was designed to have a large entrance aperture and to diffract light between and nm with a high spectral by: The peak transmission is a function of the center wavelength of the pass band as well as the number of optics in the Tunable Filter.

This means that the peak transmission is highly dependent on the optical finesse, since higher finesses have more optics and hence more absorptive elements. Optical spectral filters are based on interference, diffraction, or ab-sorption, and they are used in fixed and in tunable filters.

In this chapter, we examine the following filters: • The Fabry-Perot interferometer • The Bragg reflector • Dielectric thin-film interference • The acousto-optic tunable filter • The absorption filter.

An acousto-optic tunable filter designed for microscopy typically consists of a tellurium dioxide or quartz anisotropic crystal to which a piezoelectric transducer is bonded. In response to the application of an oscillating radio frequency (RF) electrical signal, the transducer generates a high-frequency.

acousto-optic physical principles - main equations An RF signal applied to a piezo-electric transducer, bonded to a suitable crystal, will generate an acoustic wave.

This acts like a “phase grating”, traveling through the crystal at the acoustic velocity of the material and with an acoustic wavelength dependent on the frequency of the RF. This paper reviews the theory, techniques, and applications of acousto-optic tunable filters (AOTF). Two basic types of AOTF are described, i.e., the collinear and the noncollinear configurations.

The diversity of applications demands a wide range. An acousto-optic tunable filter is used to capture individual spectral band images at a nm resolution. All spectral band images are spatially registered with the reference band image at nm to obtain exact pixel correspondences by compensating the offsets caused during the image capture procedure.Compact high-resolution spaceborne echelle grating spectrometer with acousto-optical tunable filter based order sorting for the infrared domain from to m Dennis Nevejans, Eddy Neefs, Emiel Van Ransbeeck, Sophie Berkenbosch, Roland Clairquin, Lieve De Vos, Wouter Moelans, Stijn Glorieux, Ann Baeke, Oleg Korablev, Imant Vinogradov,Cited by: A compact, solid-state, high-resolution spectrometer consisting of an acousto-optic tunable filter (AOTF) and a fiber-optic Fabry{endash}Perot (FFP) interferometer has been developed.
