The surface roughness of mirrors determine the quality of imaging in an optical system
and it depends on the optical processes and the characteristics of material itself
for example
the grain size
flaws
porosity and pore size of materials have great effect on the surface roughness. Therefore
a model was built by geometry method for the relationship between porosity
ρ
and pore size
d
the function relationships among number of pores
N
V
or
N
S
are described. Another model used to simulate the effect of porosity and pore size on surface roughness
R
A
was constructed by mathematical method. The dependence of
R
A
on
ρ
and
d
is given.
