Abstract:The subpixel dynamic imaging technique of a beam splitter is one of the most effective super-resolution imaging methods. Aiming to create a linear time delay integration charge coupled device (TDI-CCD) subpixel imaging system based on the optical assembly method, its modulation transfer function (MTF) is analyzed based on the spatial over-sampling theory. Firstly, Fourier transformation of the sampling point is used to describe the frequency domain characteristics of TDI-CCD, which transform a unit cell of the spatial sampling lattice into a bandwidth cell in the spatial-frequency domain. Considering the effects of velocity mismatch and misalignment, the best subpixel staggering position of the linear TDI-CCD pair is given. Moreover, according to the analysis of the MTF of super-resolution reconstruction results from multiple subpixel images with random spatial offsets, the condition of sampling in the limitation of the enhancement of MTF is obtained. The numerical simulation and real experimental analysis reveal results that are consistent with the theoretical model.
Conventional surface-enhanced Raman scattering (SERS) has a poor surface reproducibility, which led to measurement repeatability becoming unreliable, therefore, it is not suitable for quantitative analysis. With the rapid development of nanotechnology in recent years, highly ordered and controllable SERS substrates have been realised, so as to ensure the accuracy of measurements, and SERS signal enhancement factor has also greatly increased. In this research we have undertaken two step innovative research on Nano structured arrays for Raman signal enhancement; and channel waveguide evanescent field emission Raman signal, followed by further exploring and developing in to a high-sensitivity integrated optical SERS sensing device with practical value, which can be used in the fields of detecting contaminants, medical diagnostics, gene research and rapid identification applications.
Optofluidics is increasingly gaining impact in a number of different fields of research, namely biology and medicine, environmental monitoring and green energy. However, the market for optofluidic products is still in the early development phase. In this manuscript, we discuss modular platforms as a potential concept to facilitate the transfer of optofluidic sensing systems to an industrial implementation. We present microfluidic and optical networks as a basis for the interconnection of optofluidic sensor modules. Finally, we show the potential for entire optofluidic networks.
