Wechselblendenprinzip

Deutsch > Englisch Technik Architektur Building surveying
Context:

"Für die Auswertung müssen die Aufnahmen des Stereobildpaares den Augen des Operateurs getrennt zugeführt werden, damit die gleiche Situation wie beim natürlichen Sehen vorliegt.
Die Bildtrennung kann optisch erfolgen mit Stereoskopen oder – bei digitalen Aufnahmen heute meist üblich – mit Shutter-Brillen nach dem Wechselblendenprinzip."

I know the principle, but can't find the correct technical term inthe context of stereo photogrammetry. I am guessing at something like "alternating shutter principle", but can't find anything to confirm this.

* Sentence or paragraph where the term occurs: See above
* Document type: Book
* Target audience: Surveyors/architects
* Country and dialect (source): German
* Country and dialect (target): British English

Ich denke es heisst auch “Prinzip der zeitlichen Bildtrennung“, jetzt muss man nur den englischen Begriff dafür finden;-)

maybe this isn't that far off.
“Anaglyph images are used to provide a stereoscopic 3D effect, when viewed with glasses where the two lenses are different (usually chromatically opposite) colors, such as red and cyan. Images are made up of two color layers, superimposed, but offset with respect to each other to produce a depth effect“
“When viewed through the 'color coded' 'anaglyph glasses', they reveal an integrated stereoscopic image.“

https://www.stereoscopy.com/faq/anaglyphs.html
So, maybe “anaglyphs principle“, but would need to google more I guess
(I was just curious)
I googled “shutter“, “aperture“ “focal length“, all terms for “Blende“.

“The Glasses alternately darken over one eye, and then the other, in synchronization with the refresh rate of the screen, while the display alternately displays different perspectives for each eye, using a technique called Alternate-frame sequencing“

This might be the "active shutter" principle

Not my area of expertise, but I was curious ;-)
