Figure S9. Depth resolution of NIR-LFC. As the position and
orientation of microlens arrays (MLAs) is fixed at B , a simple
triangulation and thin lens equation from MLAs and objective lens can
estimate the depth resolution of LFC without the need of a 3D
calibration of the system. We considered the depth resolution along a
line parallel to the optical axis and halfway between the two
microlenses, apart from κ D. Note that a κ is a measure of
the distance between the microlenses centers that are used for
triangulation. An image point at distance x from the micro image
center intersects the central bisecting line at point z (x )
is defined as \(\frac{1}{x}\bullet\frac{\text{κBD}}{2}\). A simple
thin lens equation of z (x ), BL ,B , and fL calculate the depth resolution
in each a) Keplerian configuration and b) Galilean configuration. c)
Depth resolution of NIR-LFC is determined by the pre-determinedBL , B , and fL from
Supplementary text and Fig. S6, and calculated as 1.7 mm. The κis set to 2 assuming that the nearest distance between microlenses
generate the highest depth resolution.
