Depth of view increases PRF decreases
Refraction if only two oblique incidence
conditions are satisfied different propagation speeds of two media
change in direction of wave propagation when
refraction traveling from one medium to another
transmission with a bend
small diameter high frequency crystals
higher frequency creates deeper focus
-Larger diameter PZT
deep focus
-Higher frequency
-Smaller diameter PZT
shallow focus
-Lower frequency
transducer diameter goes up
focal depth and xducer
focal depth goes up
diameter
directly related
focal zone half located in near zone half located in far field
, -Far field
far zone -Fraunhofer zone
starts at focus and extends deeper
focal depth
focal length near zone length
distance from transducer to the focus
intensity of the portion of the incident beam that after
transmitted intensity
striking a boundary continues forward
the intensity of the proportion of the incident sound
reflected intensity
beam that after striking a boundary returns back
sound waves intensity immediately before it strikes a
incident intensity
boundary
near zone
near zone fresnel zone
region from the xducer to the focus
occurs when the incident sound beam strikes the
oblique incidence
boundary at any angle other than 90 degrees
oblique incidence -Not right angle
synonyms -Non-perpendicular
the incident sound beam strikes the boundary at
normal incidence
exactly 90 degrees
normal incidence perpendicular, orthogonal, right angle, 90 degrees
synonyms
oblique angles angles with a measure other than 90 degrees
obtuse angle more than 90 degrees
right angle 90 degree angle
acute less than 90 degrees
incidence the angle at which the wave strikes the boundary
