acousto optic develop

Acousto-optic imaging (AOI) is a non-invasive method that uses acoustic modulation to map the light fluence inside biological tissue. In many AOI implementations, ultrasound pulses are used in a time-gated measurement to perform depth-resolved imaging without the need for mechanical scanning. However, to achieve high axial resolution, it is required that ultrasound pulses with few cycles are This report contains all findings of the acousto-optic technology study for feature extraction conducted by Deft Laboratories Inc. for the U.S. Army Engineer Topographic Laboratories. The objective of this program was to develop, analyze and evaluate theoretical concepts and strategies for topographic feature extraction and image analysis using acousto-optic (A-O) technology.

New Method to Calculate Spatial Distribution of Acousto

Acousto-optic (AO) devices are widely used in image processing, laser spectroscop,y optoelectronics, medicine, etc. [1 3]. of AO interaction, it is necessary to develop an e ective method of precise and fast calculation of M 2 coe cient for arbitrary directions of

Acousto‐optic images provide complementary information to ultrasound images, though they are not easy to interpret alone. The acousto‐optic imaging technique was able to locate regions that were not ultrasonically detected so that it may offer a complementary

In this paper, we introduce an acousto-optic finite-difference frequency-domain (FDFD) technique in order to perform first-principles calculations of the photon-phonon interactions in acousto-optic devices. In the frequency domain, the physics of the acousto-optic system can be rigorously formulated as a system of coupled nonlinear equations, whose solution provides the steady-state dynamics
