kensho BSED

See the true nature of things.

The kensho versus a standard BSED

Mouse skin, imaged under identical high-speed, low-dose conditions on each detector.

Standard BSED — noisy, low contrast image
Kensho BSED — crisp, high signal-to-noise image

Equalised. Still different.

Histogram equalisation on both frames — this is not a contrast trick. The standard detector is noise. The kensho still has signal.

Push in and the standard BSED is static. The kensho still resolves a real feature — same speed, same dose.

Everything on this page comes down to one idea: collect more of the signal the sample already emits. The rest — the speed, the contrast at low kV — follows.
