The feedback of respective planet carrier angle-position encoder is set, controls two sets of respective planet carriers of non-axis transmission scanning means relative to rack
Corner keep size identical, make between fixed projector and scan screen for the non-axis transmission scanning means of projection imaging
Light path remains unchanged.
3. a kind of non-axis transmission scanning means shown for reflective projection imaging volume, comprising: fixed projector, first solid
Determine reflective mirror, second fixed counter-mirror, fixed barn door and two nested structures it is similar, by multiple scan screens and scan screen
The non-axis transmission scanning means that the equal double output shaft electric machines of quantity, two single output shaft electric machines and two planet carriers are constituted；Wherein one
Set is used for reflective projection, another set of to be used for projection imaging；Two sets of non-axis transmission scanning means scan screen quantity having the same；With
It is the non-axis transmission scanning means for projection imaging in the circular translational radius of the non-axis transmission scanning means of reflective projection
The half of circular translational radius；
Double output shaft electric machines are powered using wireless power source, and the winding of double output shaft electric machines is mounted on stator, each scan screen and respectively
The stators of double output shaft electric machines be connected, the two ends of rotor of respective double output shaft electric machines is connected in two rows by round uniformly distributed mode
Between carrier；In one end in the stator of each double output shaft electric machines and between a planet carrier, scan screen corner coding is installed
Device, the corner for feedback scan screen relative to planet carrier；A single shaft electricity is respectively fixedly connected on the outside of the center of two planet carriers
The stator of the rotor of machine, two single output shaft electric machines is connected with rack；Between the stator and planet carrier of a single output shaft electric machine
Planet carrier angle-position encoder is installed, for feeding back corner of the planet carrier relative to rack；According to scan screen angle-position encoder with
The feedback of planet carrier angle-position encoder controls corner and planet carrier corner relative to rack of each scan screen relative to planet carrier
Keep size identical, contrary, to realize the circular translational scanning of each scan screen；
Non-axis transmission scanning means for reflective projection is mounted on from fixed projector to the non-axis transmission for projection imaging
In projecting light path between scanning means；First fixed counter-mirror and second fixed counter-mirror are also equipped in projecting light path
To fold and adjust projecting light path, it is located at projecting light path opposite side and fixed barn door is housed；According to two sets of non-axis transmission scanning dresses
The feedback of respective planet carrier angle-position encoder is set, controls two sets of respective planet carriers of non-axis transmission scanning means relative to rack
Corner keep size identical, make between fixed projector and scan screen for the non-axis transmission scanning means of projection imaging
Light path remains unchanged.
