non-ideality. The error is at most half a pixel in situation that one edge of a LED's
image falls around the center of a pixel and two LEDs' images will form an error of
one pixel together at most.
Reviewing all the results, the experiment demonstrates nearly 98% images in favor
of the MDD prediction and strongly supports the formula for both of ARP and MDD
we achieve in chapter 3.

Conclusions
This paper abstracts two equivalent models of human eyes' imaging and photo-
sensing parts, and then constructs HIS, an innovative imaging system which integrates
main features of human eyes and many other practical imaging systems. We derive
criteria of point-distinguishability for HIS and define its resolving power by Ray-
leigh's law and theory of receptors, which restrict the resolving power of HIS. By
these criteria and definition, we propose two sets of formulas for ARP and MDD cal-
culation, involving feature parameters of HIS and object points' variables. The expe-
riment result shows that predictions of the resolving power calculation formulas for
HIS are congruous with reality, with nearly 98% correct ratio. We have successfully
simulated HIS and integrated the formulas of its resolving power in a multi-resolution
object 3D models recognition computer program. The results provide supports for
outstanding efficiency and applicability of HIS and relevant resolving power calcula-
tion in 3D mesh management. Future work includes evaluation of other factors related
to resolving power of HIS and further application in computer.
