🔦 iMarker Variants
iMarkers offer production flexibility, enabling design and detection across the entire light spectrum. These variants include UV-range (entirely transparent and invisible to the naked eye), IR-range (similarly discreet), and visible-range iMarkers designed to blend with patterned backgrounds or camouflage against similarly colored surfaces.

📷 iMarker Detector Sensors
Due to the versatility of iMarkers, various sensors can be designed and employed to detect and recognize them. So far, three primary solutions are proposed, including “dual-vision,” “dynamic single-vision,” and “static single-vision.” You can see some implemented setups below.
-
Dual-vision setup, containing to cameras facing a cube beamsplitter
-
Dual-vision setup, containing to cameras facing a plate beamsplitter
-
Single-vision setup with a fixed plarizer attached to the camera's RGB lens
-
Single-vision setup with a circular polarizer switching between left- and right-handed modes, driven by a function generator
