Dynamic holographic optical bottles for selective manipulation and merging of multiple absorbing particles
Fig. 1. Schematic implementation of dynamic holographic OBs. (a) Schematic experimental setup for generating versatile OBs. GP, Glan-Taylor prism; BE, beam expander; SLM, spatial light modulator; L1–L5, lenses; CA, circle aperture; M, mirror; C, cuvette; MO, microscope objective; CMOS, complementary metal oxide semiconductor. (b1), (b2) Schematic diagrams of selective switching and moving of two OBs.
Fig. 2. Numerical side views of OBs of dynamic manipulation steps. (a) Two steps of a single OB “on/off” operation. (b) Two steps of selectively turning off one of two OBs. (c) Five steps of selectively moving and turning off one of two OBs. (d) Four steps of merging two OBs into one and then moving it. See Appendix
Fig. 3. The trapping performance of OBs and the switching of OBs to release MCMBs. (a) Vibrational positions of the trapped MCMBs. Red dots mark the positions of the MCMBs in 2000 frames of
Fig. 4. Experimental results of selective moving of OBs to selectively transport and merge targeted MCMB clusters. (a1)–(a5) Experimental photographs of selectively moving and turning off one of two OBs. (b) Position trace of the moving particle cluster. (c) Instantaneous velocity of MCMBs transport and the corresponding polynomial fit (red line) during selective OB movement. (d1)–(d4) Experimental photographs of merging two OBs into one.
Fig. 5. The interference behavior of different focus positions. (a)–(d)
Fig. 6. Comparative analysis between a single OB and two OBs. (a) Side views of a single OB and two OBs. (b1), (b2) Trapping stiffness in
