IIT Indore’s photogenic triumph

IIT Indore has developed an innovative low-cost camera set up in collaboration with NASA-Caltech, US, and the University of Gothenburg, Sweden. Using a single DSLR camera, it can simultaneously capture multiple spectral three-dimensional images of four chemical species in a flame; previously scientific imaging required a complex system with four cameras.

The innovation will expedite the study of fuel combustion which in turn can make combustion engines more efficient and environment-friendly. A careful study of the elements released from the combustion of fuel in industrial burners and engines, including vehicles, airplanes, and spacecraft, will lead to needful improvements, thereby reducing carbon and greenhouse gas emissions.

• The cost of making the DSLR camera device is only Rs 50,000, the outcome of an intensive five-member research spanning three years
• The researchers employed the method of Structured illumination, which enables imaging of low-intensity species using a DSLR camera which otherwise requires intensified CCD cameras
• The research team now intends to explore the applications of this radical approach in biomedical imaging, ultrafast imaging, multidimensional, and other advanced studies in combustion
