The principle of work of a kind of object system motion state of the present invention analyzer:
During measurement, object system and geo-stationary of the present invention, first photographic layer 6 starts to move up or down, and then parallel light source 5 sends parallel beam 8, and center is incident upon in reflection circle cone 4, the photographic layer 6 in the folded light beam 9 horizontal sheaf motion of parallel beam 8.When object system direction of motion is parallel with parallel beam 8, the photon of folded light beam 9 evenly drops on photographic layer 6, and exposure obtains the consistent exposure bands of bandwidth 10; When object system direction of motion and parallel beam 8 in an angle time, the photon of folded light beam 9 exposes on photographic layer 6, make the bandwidth of exposure bands 10 inconsistent, there is narrow bandwidth and wide bandwidth, the side of exposure bands 10 object system direction of motion dorsad, the exposure area of photographic layer 6 is compressed, and occurs narrow bandwidth; Exposure bands 10 and object system direction of motion side in the same way, the exposure area of photographic layer 6 is then elongated, and occurs wide bandwidth.
When a kind of object system motion state of the present invention analyzer uses, as follows:
1, first object system motion state analyzer and object system keep geo-stationary, start jacking gear 7, make cylindrical drum 2 and photographic layer 6 uniform motion upwards or downwards;
2, parallel light source 5 is opened, parallel beam 8 is hit exactly and projects reflection circle cone 4 top, parallel beam 8 is by the conical surface horizontal reflection of reflection circle cone 4, on the photographic layer 6 of the even directive of folded light beam 9, the photon numbers of all directions reflection is identical, photographic layer 6, by the then corresponding exposure of folded light beam 9 projected area, forms exposure bands 10;
3, when cylindrical drum 2 and photographic layer 6 move to desired location, close parallel light source 5, after photon is all received by photographic layer 6, jacking gear 7 stops and resetting;
4, as shown in Figure 3, to determine in exposure bands 10 that bandwidth is the widest with the narrowest position, i.e. narrow bandwidth 12 and wide bandwidth 11 respectively, the mid point between line narrow bandwidth 12 and wide bandwidth 11, this line perpendicular to the axis of reflection circle cone 4, and is parallel to reflection circle cone 4 bottom surface; Record the link position of this narrow bandwidth 12 mid point and wide bandwidth 11 mid point.
5, object system motion state analyzer is rotated 45 ° to the widest or the narrowest direction of first time exposure bands, then the mid point direction to line described in step 4 rotates 45 °, repeat above-mentioned steps 1-4, Article 2 exposure bands 10 can be obtained, every bar exposure bands 10 all there are narrow bandwidth 12 and wide bandwidth 11, and then the line that can obtain described in Article 2 step 4, record its position;
6, twice step 1-5 is obtained 2 line translations intersect, determine a plane, this plane is vertical with object system direction of motion, then does one perpendicular to this plane, and this straight line points to wide bandwidth 11 side, is the direction of motion of object system.
