Figure 3. Optical focusing in 2-mm-deep chicken tissue.
Two pieces of 2-mm-thick chicken tissues were used as diffusers. (a) A microbubble in a tube before destruction. (b) After destruction. (c) A light focus was created at the position of the destroyed microbubble (PBR ∼23). (d) The optical focus vanished as the SLM shifts 10 pixels in both x and y directions. (e) 10X zoom-in image of the optical focus with quantified resolution. (f,g) Central part (200 pixels by 200 pixels) of the optical fields captured before (f) and after (g) the destruction of the microbubble. (h) Difference of the fields in f,g. Scale bar, 10 μm.
