The following are key elements of a frequency domain fluorescence lifetime imaging system: (1) a standing wave acousto-optic modulator (SW-AOM) that modulates the intensity of the excitation light source at high frequency and (2) a frequency mixing device, such as an image intensifier, to perform phase-sensitive detection of the fluorescence emission. Figure 1
shows a single-frequency FLIM configuration. The instrument is based around a vibrationally isolated, inverted microscope (e.g., Zeiss Axiovert 135 TV). The basic light source requirement is an argon laser with sufficient output power (>100 mW per line). The 457-nm, 488.0-nm, and 514.5-nm lines are ideal for excitation
