PCT No. PCT/GB91/00046 Sec. 371 Date Sep. 11, 1992 Sec. 102(e) Date Sep. 11, 1992 PCT Filed Jan. 14, 1991 PCT Pub. No. WO91/10897 PCT Pub. Date Jul. 25, 1991.Apparatus for producing decay time weighted information (e.g. a decay time weighted image) of a luminescent sample, comprises an excitation light source arranged to illuminate the sample, means for modulating or pulsing the intensity of the excitation light in a predetermined cyclical manner, detector means for detecting photons emitted by the sample as a result of luminescence, means for storing data representative of detected photons, the stored data being weighted as a function of phase difference between detection of photons and the cyclically varying modulation, and means for producing decay time weighted information from the stored data.
