Abstract
An apparatus comprising a spectral filter () with a variable spectral filter transmission (FT(λ)); an event-based imaging sensor () configured to produce measurement events (y, y, . . . , y) which correspond to a change in a filter response (Y(t)) that is generated by an observed spectrum (X(λ)), and a processor () configured to control the filter transmission (FT(λ)) of the spectral filter () so that it sweeps over wavelength (λ) with time (t), and to generate an estimation (X*(λ)) of the observed spectrum (X(λ)) based on the measurement events (y, y, . . . , y) that correspond to the filter response (Y(t)) and based on the filter transmission (FT(λ)).
