Question | Answer |
---|---|
Period | 1/frequency |
Frequency | 1/period |
Intensity | power (watts)/beam area (cm2) |
Beam Uniformity Coefficient (BUC) | spatial peak intensity (w/cm2)/spatial average intensity (w/cm2) |
wavelength | propagation speed/frequency |
Duty Factor | pulse duration (sec)/pulse repetition period (sec) x 100 |
Spatial Pulse Length | # of cycles in pulse x wave length (mm) |
go-return-time | depth of sample volume x 2/propgation speed (mm/us) |
Nyquist limit | PRF/2 |
LARRD = | spatial pulse length (mm)/2 |
