Using Biological nanostructures and holography we are trying to demonstrate of a novel multispectral imaging camera. We use insect (butterfly) wings as a biological nanostructure for sensing with possibility to use artificial structure in a future. These butterfly wings in combination with thermophoretic effect can be used for optical reading. Structures in wings absorb some portion of light, which results in slightly higher temperature of the surrounding gas on the irradiated side (compare with opposite side). This temperature difference creates a mechanical pressure acting on one side. Very small pressure creates very small mechanical deflection, but at the end it can be detected with sensitive holographic technique. Experimental setup is configured as a Twyman – Green interferometer for holographic microscope, and He- Ne laser as a light source. We use additional laser to heat just a part of the wing. Afterwards, thermal response can be reconstructed from the recorded hologram. In collaboration with ORQA, company from Osijek, we are in procedure of development a standalone device for real time reconstruction. This device is equipped with state of the art nVidia graphic processor for fast image reconstruction. We aim to achieve real time thermal imaging camera as a standalone device with artificial sensing component. |
