Abstract

A method and apparatus are provided for generating a thermal image of a target. The method comprises: at one or more electro-magnetic transducers, receiving long wave infra-red (LWIR) radiation emitted from the target; illuminating the electro-magnetic transducers with radiation being transmitted wavelengths that belong to Near Infra-Red (NIR) band and/or that belong to the visible (VIS) band; converting at least part of the radiation received as LWIR radiation to energy at the NIR band and/or at the VIS band; and generating a thermal image based on the energy retrieved after converting at least part of the LWIR radiation received, to energy at the NIR band and/or at the VIS band, and wherein receiving the LWIR radiation and illuminating the electro-magnetic transducers, are carried out simultaneously.
