Quantum Dot Film Imaging Research Based On MEMS Micromirror

People have always been concerned about human health.Scientific research on human disease detection and diagnosis has never stopped.In recent years,the key technologies such as nano and biological imaging have developed rapidly.At the same time,nanoimaging probes have been used more and more in the field of biological imaging.This will promote the development of biomedicine,chemistry and materials science if the technology can be used to improve the resolution of imaging and to extract the image information of the larger quantum dots of the field of view.This is also the significance of many experts and scholars to conduct in-depth research on it.MEMS micromirror as an adjustable reflector can be applied to miniaturization system to achieve real-time and fast high-resolution imaging.Imaging spectroscopy is a new technology combining imaging technology with spectroscopy.This technology can achieve the synchronous acquisition of spatial information,radiation information and spectral information of the target.In this paper,we have carried out experiments on a small-scale detection prototype system of the nano quantum dots protein chip.The experiment has completed the research of high resolution and wide field microscopy imaging technology.The main research work has the following aspects:1.design of microimaging system.Based on the basic theory of microscopic imaging and the needs of the detection of nano quantum dots biochips,a miniaturized quantum dots biochip detection prototype was built.On this system platform,C and C++ language are used to compile the control software of the slave computer and the host computer respectively.And then the specific functional requirements of the test experiment are realized.2.improvement of image stitching algorithm.In order to obtain large field of view imaging,image mosaic is needed for the collected microscopic images.However,considering the low precision of the traditional BRISK image stitching algorithm,this paper makes a corresponding improvement in this paper,so that the algorithm can achieve fast and accurate image stitching.3.a multidimensional imaging scheme is proposed.In view of the application requirement of obtaining spectral information of every point in microscopic images.In this paper,a new image and spectral information acquisition scheme is developed.On the basis of this,the integration of one-dimensional spectral information and twodimensional image information is realized.The performance of the designed technology is verified by corresponding experiments.The final implementation of the system has good innovation and application value.Some limitations of the thesis are summarized.Aiming at these shortcomings,the next research direction has been worked out.Then some suggestions for further development of related technologies are put forward.
