Abstract
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.
