θ1=θ2=θ3=60 °>θC (9)
Wherein, arc point a, b, c position, it is to be symmetrical with center of circle d and be distributed with 60 ° of angles, i.e. Δ abd, Δ bcd are all
For equilateral triangle.θ 1 is for a points, the incident angle of incident light 171；θ 2 is for the b points, the incidence of incident light 172
Angle；θ 3 is the incident angle for the c points incident light 173；θ C are the angle of total reflection.Certainly, according to the reversible phenomenon of light, for
The above-mentioned parallel input light 171 from the base 161 and total reflection light 174, it is reversible for optical propagation direction, and complies fully with formula
(8) relation.In addition, θC, R, with H there is following relation：
θC=sin-1(n2/n1) (10)
H=R (1-cos α) (11)
P=2R sin α (12)
Wherein, α is half angle of the circular arc 154 to center of circle d, and with relation once：
α>θC (13)
It is somebody's turn to do to meet the relation of formula (8), i.e. θ C<60 °, n1With n2Between, there is following relation：
n2/n1<sin(60°) (14)
Sin (60 °)=0.866 is made, then can obtain following relation：
n1>n2/0.866 (15)
Make Δ n=n1–n2, then following relation can be obtained：
Δn>0.1547n2 (16)
R, α, H, become in volume to volume ultraviolet curing moulding process, the parameter needed for cutter carved corresponding to mould,
Wherein, R is radius of edge, α is cutting edge half angle degree and H be then align target be carved into depth.Therefore above-mentioned carving can be generally called
Icking tool tool is " round contraposition target graver tool " (not shown), and make the basic design parameters that R, α, H are the engraving cutter.Separately
Outside, final round contraposition target graver tool, the image line width of the tool light total reflection contraposition target presented, is decided by P.Also
That is, R, α determine the image line width of final contraposition target.Typically, had using the round contraposition target graver, in being done on mould pair
During the engraving of position target, in fact, contraposition target can be engraved as into crosswise, after volume to volume ultraviolet curing shaping, this ten
Shape aligns the 3D geometries of target, i.e., as shown in Figure 10.
