Illustrate that the concrete four-dimension of the four-dimensional debugging device of extreme ultraviolet reflecting optics of the present invention regulates referring to Figure 11 to analyze.Figure 11 is the kinematic sketch of the four-dimensional debugging device of extreme ultraviolet reflecting optics of the present invention.As shown in figure 11, the first regulating system 6 mounting points on vacuum chamber 1 is respectively D1 (a1, b1, c1), D2 (a2, b2, c2), D3 (a3, b3, c3); Second regulating system 7 mounting points on vacuum chamber is D4 (a4, b4, c4); On lens support frame, regulating system mounting hole is A1 (x1, y1, z1), A2 (x2, y2, z2), A3 (x3, y3, z3); Sliding ball sphere center position (i.e. the intersection point of each turning axle of lens support frame) is A4 (x4, y4, z4); At grade, A1, A2, A3, A4 4 at grade for D1, D2, D3, D4 4; Bar A1B1, A2B2, A3B3 are all vertical with plane A1A2A3A4, and bar D1C1, D2C2, D3C3, A4D4 are all vertical with plane D1D2D3D4.
To arbitrary system, in four-dimensional adjustment process, D1, D2, D3, D4 4 then volume coordinate that immobilizes is known; The distance of B1C1, B2C2, B3C3, A1B1, A2B2, A3B3 is the length of bar, remains unchanged and known; The distance of D1C1, D2C2, D3C3, A4D4 is determined by the first regulating system and the second regulating system, can be considered known input quantity.
Every root bar and plane orthogonal, namely with two linear vertical that plane does not overlap arbitrarily, can list two separate equations.Vertical with plane A1A2A3A4 for bar A1B1, if

Like this, vertical with plane D1D2D3D4 by bar D1C1, D2C2, D3C3, A4D4,8 separate equations can be listed; The distance of D1C1, D2C2, D3C3, A4D4 is known input quantity, can list 4 separate equations; These 12 equations of simultaneous, can solve the volume coordinate of C1, C2, C3, A4 4.
In like manner, all vertical with plane A1A2A3A4 by bar A1B1, A2B2, A3B3,6 separate equations can be listed; The distance of B1C1, B2C2, B3C3, A1B1, A2B2, A3B3 is known quantity, can list 6 separate equations; In plane A1A2A3A4, the distance of A1, A2, A3, A4 4 middle any two points is known quantity, can list 6 separate equations; These 18 equations of simultaneous, can solve the volume coordinate of A1, A2, A3, B1, B2, B3 6.
So, by three the first regulating systems and second regulating system, uniquely can determine the locus of lens support frame (containing reflecting optics), thus uniquely can determine that lens support frame (containing reflecting optics) is relative to the one-dimensional translation of vacuum chamber and Three dimensional rotation.
But, it should be noted that A1, A2, A3 and A4 should not on the same line, if because they are on same straight line, just uniquely can not determine plane A1A2A3A4, then
with
equivalence, can not list separate
with
two equations, just can not solve the locus that thus whole unknown volume coordinate uniquely can not determine lens support frame (containing reflecting optics).In like manner, D1, D2, D3 and D4 should be not on the same line yet.
More directly, as shown in Figure 11, with D4 be initial point,
for x-axis forward,
setting up coordinate system XYZ for z-axis forward is bundled on vacuum chamber; With A4 be initial point,
for x ' axle forward,
setting up coordinate system X ' Y ' Z ' for z ' axle forward is bundled on lens support frame; Can mutually change between these two rectangular coordinate system in space, conversion relational expression is the function of one-dimensional translation displacement and Three dimensional rotation displacement, is specially:
Δ Z is translation displacements parameter, R (ε
