Multiband flash detection system |
摘要 |
A multiband imaging system comprising: an optical module configured for acquiring simultaneously images from a common field-of-view (FOV) scene in a short wavelength spectral band and in a long wavelength spectral band, the optical module comprising a polarizer configured for applying polarization filtering to electromagnetic radiation of the long wavelength spectral band; and a processing module configured to analyze data indicative of received irradiance distribution between the short and long wavelength spectral bands. |

1. A multiband imaging system for detecting muzzle flashes, comprising:
a short wavelength imaging module configured for acquiring an image in a short wavelength; a long wavelength imaging module configured for acquiring an image in a long wavelength, where the short wavelength and long wavelength imaging modules simultaneously acquire images from a common field-of-view (FOV) scene in a short wavelength spectral band and in the long wavelength spectral band, respectively; a polarizer configured for applying polarization filtering to electromagnetic radiation of a long wavelength spectral band entering the long wavelength imaging module to filter out specular reflections from surfaces having roughness close to the short wavelength and smaller than the long wavelength; and a processing module configured to analyze data indicative of received irradiance distribution between the short and long wavelength spectral bands for determining the muzzle flashes. |
