Fig. 1.

Simplified schematic diagram of the combined TPM-SDCM system. The TPM beams appear in dark red; the fluorescent excitation beams appear in green and the fluorescent emission beams appear in blue. The LC-SICA module is placed at the output of an IX83 microscope for low-coherence phase imaging. The scanning confocal unit is for 3D fluorescent imaging. AOTF, acousto-optic tunable filter; M₁, M₂, M₃, mirrors; S, sample; MO, microscope objective; TL, tube lens; BS, beam splitter; IP, image plane; G, grating; L₁, L₂, lenses with focal lengths f₁=150 mm and f₂=300 mm. z, distance of G from IP; M, mask that selects only two diffraction orders; C, compensating plate; SD, spinning disk; DM, dichroic mirror; L₃, relay lens; LMS, laser merging module.
