Experimental setup for the generation of the ST light sheet and SH ST-like light sheet (a). Schematic of the imaging system post-diffuser using fluorescent beads and tendon as samples (b). Generation of the BG beam via an axicon lens (c). Insets show the intensity distributions of the Gaussian beam, ST light sheet, and the BG beam. For the optical components: G1 and G2: diffraction grating with 1200 grooves/mm (G1 is used in reflection mode but is depicted here in transmission mode for simplicity), BS: Beam splitter, SLM: spatial light modulator, L1, L3, and L4: Cylindrical lens, D: holographic diffuser 0.78 mm thickness, Obj: objective, S: sample, BBO: nonlinear crystals β-barium borate 1 mm thickness. F: second-harmonic generation filter and sCMOS, camera, L2, L5, and L6: spherical lens. The red arrows indicate the beam propagation direction.
