Abstract: There is provided a spectroscopy apparatus for measuring fluorescence signals from a photosynthetic object. The spectroscopy apparatus comprises:



one or more light excitation sources (26,28) operable to carry out time-varying excitation of the fluorescence from the photosynthetic object; and
one or more fluorescence-sensitive detection channels (36,38,44,46) configured to simultaneously record the fluorescence as a function of time with a microsecond to millisecond time resolution and as a function of wavelength with a wavelength resolution of 10 nm or better, responsive to the excitation of the fluorescence from the photosynthetic object by the or each light excitation source (26,28).
