Future of hyperspectral imaging

For a large part of the last three decades since its development, a hyperspectral imaging (HSI) system was assembled from assorted bulky components. The past few years has seen HSI reducing in size and weight, such that smaller hand-held portable and lightweight cameras for unmanned aerial vehicles are commonplace.

Owing to the decreasing size and cost over the last decade, HSI technology has been making its way into the mainstream consumer market. Based on the investments in 2017, the global HSI market size is forecast to increase to 21 billion USD, according to Frost and Sullivan.

Different optical arrangements for miniaturizing HSI cameras are currently being investigated. It is expected that the miniaturization of HSI to monolithic integrated circuits and the development of dedicated MEMS technology will allow mass manufacturing of HSI systems, hence driving down the price of HSI. These ongoing evolutions will enable the expansion of HSI application domains both in the industry and the consumer market.
