In face of setting；
Control device 13, control device 13 are connected with movable-component 12, for controlling movable-component 12 removable
It is moved in face where component 12, and the overlapping area of the first opening portion 111 and the second opening portion 121 is in moving direction
The distance moved on (101 direction i.e. shown in FIG. 1) is in nonlinear change.
As shown in figure 3, first opening portion 111 and the second opening portion 121 are completely wrong if movable-component 12 is in position 1
It opens, the overlapping area of the first opening portion 111 and the second opening portion 121 is zero at this time, i.e. the light transmission capacity of the light valve is zero.If removable
Component 12 is moved in position 2, then the first opening portion 111 and 121 part of the second opening portion are staggered, at this time the first opening portion 111 and the
The part of two opening portions 121 is overlapping, then the partial light permeability of the light valve.
It should be noted that in order to realize the overlapping area of the first opening portion and the second opening portion in the direction of movement
The distance moved is in nonlinear change, and the shape of the first opening portion and the second opening portion is not limited to rectangular aperture shown in FIG. 1
It is open with zigzag.Such as second opening portion can also be arc-shaped opening, trapezoid-shaped openings etc..
It should be noted that fixation kit only the first opening portion light transmission, the second opening portion light transmission of movable-component, other
Part is opaque.Then fixation kit and movable-component can be is formed by lighttight material, first opening portion
It is the part of cutting removal with the second opening portion.
