Abstract
A flash detection device comprises at least a first and a second sensor module, wherein each of the sensor modules comprises at least a photodiode for detecting an irradiance emitted by a source, and the first sensor module comprises at least an angular efficiency attenuator configured for attenuating the irradiance received by the photodiode according to a predetermined angular efficiency profile, wherein the at least first and second sensor modules are configured for collecting light from substantially the same field of view, and the angular efficiency attenuator of the first sensor module causes the first and second sensor modules to have complementary predetermined angular efficiency profiles, so that, for angles of view within a common field of view of the first and second sensor modules, a combination of irradiance measurements of the first and second sensor modules enables to derive an irradiance source angle of the source.
