The traditional magnifying and microscopic observation is realized by means of a magnifying glass and a microscope, if an image is to be acquired, the image is generally required to be acquired by connecting a camera, and along with the digital development of the image and the popularization of a computer, the electronic microscope can observe by using a display and acquire the image by means of connection with the computer. The magnifier has the characteristics of low cost and portability, but has limited magnification, and the image is difficult to collect. The microscope has high precision, but is heavy, complex and expensive, and the image acquired by the computer is very tedious and subject to a lot of restrictions. The image acquisition, arrangement, storage and transmission links are obviously important as the observation purpose and achievement, and are focuses of attention, and the workload of the image acquisition, arrangement, storage and transmission links also occupies a very large specific gravity in the whole amplifying or microscopic activity.
Smart phones and mobile interconnect technologies bring new solutions to this, creating a subversion impact. The main current smart phones mostly have very powerful functions of shooting, storing, transmitting and managing images and images, but the lens focus Duan Hennan of the smart phones takes account of shooting of micro-distance or close-distance objects. Due to the limitations of imaging principles and the size of the mobile phone, the requirement for macro shooting cannot be met even if the zoom capability of the mobile phone is improved in future without an auxiliary device. Although various mobile phone accessories with micro lenses for macro shooting appear on the market, most of the mobile phone accessories are connected with a mobile phone in a clamping mode, and the mobile phone has the advantages of small size and portability, but the mobile phone accessories have obvious defects. Firstly, when the existing mobile phone accessory with the microlens is clamped on a mobile phone to shoot, a handheld method is generally adopted to shoot, absolute stability cannot be kept, imaging cannot be kept parallel to a shot object, and the situation can cause image blurring and distortion due to any tiny shake and skew, so that the quality of an observed and collected image is difficult to guarantee, and the mobile phone accessory with the microlens can be used as a general interesting experience, but cannot be applied to formal and professional work and research. Secondly, the small advantage brings the defect of small field of view simultaneously, and the requirements for identification, quality control, scientific observation and the like can not be met. In addition, the clamping type accessory is required to be held for shooting, so that the display screen is necessarily shielded, observation is prevented, and the operation is inconvenient. The clamped micro-imaging assembly generally has other disadvantages such as blurring around the image because of pursuit of small portability.
