针对现有的反射式或衍射式光学读出系统的复杂性和体积庞大性，提出了一种基于热光腔耦合等离子体散射的红外成像传感器光学读出新方案。这种新的方案读出大角度暗场照明下的金属纳米结构的热调制后向散射可见光信号。通过数值模拟，揭示了金属纳米结构产生的法布里-珀罗（F-P）微腔与局域表面等离子体共振（LSPR）耦合的热光效应导致的高温度灵敏度和低角度灵敏度的散射机理。初步的实验和光学测量结果证明了该方案的可行性。在3.39 μm红外波段获得了热光调制散射谱，在605 ~ 640 nm波段温度灵敏度达到0.24 nm/℃。该方案为研制小型化、低成本的红外成像系统提供了一种新的途径。
A novel scheme of optical readout based on thermo-optic cavity coupled plasmonic scattering for infrared imaging sensor is proposed to lessen the complex and bulky of existed systems using reflective or diffractive optical readout schemes. This new scheme readouts thermally-modulated back-scattering visible light signals of metallic nanostructures under large-angle dark field illumination. Numerical simulation is employed to reveal the mechanisms of large temperature sensitivity and low angular sensitivity of scattering, which is attributed to the thermal-optic effects of Fabry–Perot (F-P) microcavity coupled with local surface plasmon resonance (LSPR) generated from metallic nanostructures. The feasibility of the proposed scheme is demonstrated by preliminary experiments and optical measurements. Thermal-optic modulated scattering spectra have been obtained for 3.39 μm infrared illumination and a temperature sensitivity of 0.24 nm/℃ for 605 ~ 640 nm band has been reached. This scheme provides a new approach to develop compact and low cost infrared imaging systems.
