VTT creates world’s first hyperspectral iPhone camera
VTT Technical Research Centre of Finland has converted an iPhone camera into a new kind of optical sensor.
By thus creating the world’s first hyperspectral mobile device, VTT’s research is set to open new possibilities of low-cost spectral imaging to consumer applications.
The cost-effective optical MEMS (Micro Opto Electro Mechanical Systems) spectral technology enables the development of new mobile applications for environmental sensing and observation from vehicles and drones. All of this forms part of an environment combining smart sensors with the Internet.
“Consumer benefits could appear in health applications, such as mobile phones that are able to check whether moles are malignant or food is edible,” explains Anna Rissanen, head of the VTT research team, in a release. “They could also verify product authenticity or identify users based on biometric data. On the other hand, driverless cars could sense and identify environmental features based on the representation of the full optical spectrum at each point of an image.”
Hyperspectral cameras have been used for demanding medical and industrial, space and environmental sensing, and are traditionally expensive.
