Caption
(a) Sketch of the optical system. (b) CGH displayed on the SLM for the generation of a 9×9 foci array. (c) The foci array on the focal plane of Lens 1 (P plane). (d) Phase distribution and (e) intensity distribution on the entrance pupil of the objective (E plane). (f) Simulated and (g) measured multi-foci array generated on the focal plane of the objective (F plane). (h) Enlarged intensity profile of a single focal spot in the array. The arrows indicate the polarization directions. (i) Longitudinal intensity profile and corresponding line plot of the foci array. (j) Simulated and (k) measured intensity distribution on the F plane when the CGH for the generation of the pattern "E" is encoded on the SLM. (l-m) Enlarged intensity profiles of the pattern corresponding to (j) and (k) with the same sampling points as in (i).
