There are high expectations for the applications of multispectral camera systems in a wide range of industries. In response, Fujifilm has developed a multispectral camera system based on a polarization system, tapping into its optical technology, nurtured through the development of 4K/8K broadcast lenses and a wide range of other lens products, as well as the cutting-edge image processing technology nurtured through the development of the GFX/X Series of digital cameras. The high-performance multispectral camera system is equipped with a lens fitted with newly-developed filters, a polarization image sensor that can capture specific directional polarization image, and a cutting-edge image processing function. The camera system can simultaneously record images of different wavelength ranges in high definition and presenting them in real time. The newly-developed filters serve as polarizer that lets light in a specific direction of polarization pass through as well as optical bandpass filter that passes light of a specific wavelength range. The system uses three filters to split light into up to nine wavelength bands, while also polarizing the light of each wavelength band into a specific oscillation direction. The polarization information of light in each wavelength band that has passed through the filters is recorded by the polarization image sensor and applied with the cutting-edge image processing function for visual presentation in high resolution and at a high frame rate. The system also allows users to choose an optical bandpass filter of the optimum wavelength band for their monitoring object. The camera system is currently just a prototype and not yet a finished product ready for the market.
