Due to the different calorie distribution and release process of the lesion cells and normal cells, heat sensing diagnosis and treatment has become a new and effective diagnostic method in recent years. Lesion cells because of its offensive, more than normal cells stronger, more concentrated heat radiation. Through the use of high-resolution thermal imager to scan the body, especially the imaging of the fundus, can effectively achieve the early screening of the disease, greatly improve the chances of cure and enhance the quality of human life.
The existing thermal imager due to the need for infrared light with high transmittance of special materials, the general price is expensive, cannot achieve the daily equipment of the family. In addition, due to the high complexity of processing and the need for traditional lens focusing geometric curvature characteristics, generally portable miniature infrared imager resolution cannot effectively identify the accuracy of the lesion.
Swinburne University of Technology recently developed fumed graphene film lens (http://www.nature.com/ncomms/2015/150922/ncomms9433/full/ncomms9433.html) for the ultra-small high-resolution mobile phone integrated infrared thermal imaging. The technical revolution of the instrument provided the possibility. The graphene film is subjected to laser pattern processing on a very thin (~ several tens to several hundred nanometers) graphene oxide film to achieve lens function. The grained graphene lenses can be ultra-thin, ultra-compact, and easy to integrate due to the need for traditional lens-free geometrical curvatures for wave front shaping. More importantly, graphene oxide has excellent infrared transmittance, is integrated infrared components processing of high-quality materials. Therefore, it is expected that the use of an oxide graphene material is achieved by using a single material lens to cover the imaging function from visible light (current mobile phone lens) to mid-infrared (thermal sensing detection).
Project features: to achieve ultra-thin graphene lens and mobile phone combination. For the first time to expand the infrared imaging function to each mobile phone, in order to achieve high resolution thermal imaging for home treatment, housing maintenance detection, troubleshooting, night vision imaging and other functions
