Now TFM; I have a few data when I tried a large pitch probe, fewer # of active elements, and it still comparable to high number of elements, lower pitch. 🙃 Effective aperture area is the key in that case! Especially for TFM.

64e and an X3! Go TFM!! I kidding 😄 very good video. Thanks!
It's just what most people do. For the longest time, focusing at a true depth was all you *could do* on the most popular instruments. For the most part with general probes and common inspections it will work fine. Nowadays there are much more options.
And that is the big problem with focusing isn't it? Ooooh we have all these elements let's just shoot a shitload of sound all at once that will capture everything!!!!!!...........yeahhhhhh
Very easy to over-focus with large aperture/thickness ratios especially at high frequencies. Admittedly, this comparison is extreme. I'm using 64-elements at 10MHz.
Really nice video with great visuals to compare apples to apples :)
Great Paul, very clare.

Thank you for your video
Excellent once again, thank you for this. Jim H. Portland, Or
oh...pual...i miss you'r hair texture...
Hey Paul, is focussing at t x 1.5 written in a spec somewhere or is it just common knowledge amongst experienced phased array techs? Regards
