Fig. 2.

Axial response of the video-rate LS-DAC microscope to a flat reflective mirror in 5% Intralipid (or water) over a range of optical lengths ($L_P$) plotted with: (a) a linear scale and (b) a logarithmic scale. The measured half width at half maximum is $1.10\mu \mathrm{m}$. (c) Reflectance image of a 1951 USAF bar target. (d) Zoomed-in view of groups 8 and 9 of the USAF bar target. The video-rate LS-DAC microscope has the ability to resolve group 8, element 5 ($\text{line width}=1.23\mu \mathrm{m}$) of the bar target.
