Laser induced fluorescence has been used for decades to classify and identify a variety of materials. The traditional fluorescence detection method involves the use of narrow band filters or a spectrometer combined with a telescope. We propose using a multi-aperture telescope operated in Fizeau imaging mode for the projection of a pump wavelength and the collection of the fluorescence photons. The phased array is operated such that the array is optically phased for the pump wavelength and de-phased at the fluorescent wavelength thereby spatially distributing the two wavelengths in the image plane. This allows single shot identification of fluorescent modes.
