This work presents the first demonstration of a plasmonic hyperspectral camera using an active plasmonic tunable filter, showing continuous peak shifting depending on voltages. The compact plasmonic hyperspectral camera, combined with a B/W camera, was fully packaged with a total size of 16 x 16 x 28 mm. Hyperspectral imaging was successfully demonstrated using this camera, reconstructing the featured spectrum of fruits and hand vein.
This work reports the first demonstration of plasmonic hyperspectral camera by using an active plasmonic tunable filter (APTF) consisting of ultrathin angle-sensitive nanostructures and compact bimorph actuator. APTF clearly exhibits continuous peak shifting from 800 nm to 1000 nm depending on voltages with 1.0 - 3.0 V. Then, fully packaged with compact B/W camera which accomplished the compact plasmonic hyperspectral camera (PHC) with total size of 16 x 16 x 28 mm. Finally, hyperspectral imaging was demonstrated using the PHC so that the featured spectrum of fruits and hand vein was successfully reconstructed.
