The scheimpflug principle

Scheimpflugs princip är en optisk regel som beskriver i vilken riktning ett objektivs skärpeplan (objektplan) avbildas på bildplanet (fokalplanet), när objektivet inte är parallellt med detsamma. Detta tillämpas regelmässigt i en storformatskamera, eller med s.k. tilt-and-shift-objektiv i systemkameror (särskilt då tilt-funktionen). Webb6 dec. 2024 · They use a CMOS image sensor, FPGAs, and integrated 3D evaluation algorithms. C5-CS sensors also reach profile speeds of up to 200 kHz, a profile resolution of up to 4096 points/profile, and they provide the same 3D scan features as C5 sensors. The detector and optics are arranged according to the Scheimpflug principle.
