Time-resolved wavelet- based acquisitions using a single pixel camera
Résumé
We propose to couple a single-pixel camera with a unique photon counting board in order to obtain an inexpensive time-resolved imaging system having a high spatial and temporal resolution. As an alternative to compressive sensing, a wavelet-based adaptive acquisition strategy is employed that allows high compression rates with little degradation of the image quality. The applicability of our approach is demonstrated for fluorescence lifetime imaging with experimental results obtained by imaging samples embedding several fluorophores. The proposed imaging system with the wavelet-based strategy can be transposable on a microscope in order to perform fluorescence lifetime imaging microscopy measurements.
