“…In this work, the refractive indices of water (1.330), ethanol (1.362) and IPA (1.377) are taken from Palik, 9 and those of glucose solutions are calculated by the equality n = 1.33 + 0.0014x, where x stands for the concentration of the solution. 10 The relationship between the valley position and liquid refractive index was shown in Fig. 8, from which the sensitivities of the refractive index by the gold lamellae layers can be worked out as 575 and 561 nm/RIU.…”

Local plasmatic resonance existing around nanoscale metallic structures is closely related to the refractive index of the surrounding media. Gold Lamellae layers embedded in gratings are ideal to populate the plasmatic resonances locally with much higher concentration than the simple gratings, leading to enhanced sensitivity to the testing materials. Based on our earlier success in replicating dielectric lamellae layers, this paper reports our further work in converting the dielectric lamellae layers into gold ones and the study of their optical property as refractive index sensors. To prove the local surface plasmatic resonance be responsible for absorbing the light, the gratings without the lamellae layer were also tested for comparison. Both numerical simulation using the finite difference time domain method and optical measurements have demonstrated the enhanced sensitivity by the gratings with lamellae layers, although structural optimization is still needed. With the further improvement in both structural configuration, material and nanofabrication technique, it is believed that the proposed lamellae layers should be a promising candidate for highly sensitive environmental sensors.

We propose a laser heterodyne digital holography microscopy system based on a moving grating, which uses the Doppler principle between a moving grating and beam to achieve a low‐frequency bias between the diffracted beams, abandoning traditional heterodyne digital holography that requires multiple acousto‐optic modulators. The dynamic phase distribution obtained using the laser heterodyne digital holography phase‐reconstruction algorithm was more realistic and analyzable than the results of the angular spectrum algorithm. The structure and algorithm were used to capture the shape characteristics of mouse fibroblasts after ~2 h of incubation (37°C, 5% CO2), and the dynamic phase distribution of the cells was monitored in real‐time during the attachment process. The system proposed in this study, with its high spatial resolution and high‐precision phase measurement capability, is suitable for both static and live cells.
