In the present embodiment, laser instrument 10 is HONGGUANG point-like laser instrument (belonging to visible light wave range), and spot size is no more than 2 millimeters, and collimated ray can be visual, also can gather for CCD.For ease of installing/dismounting, the profile diameter of laser instrument 10 is less than φ 30mm, and contour length is less than 100mm.
Concrete enforcement of the present utility model comprises two steps, and the first step is that collimator apparatus is connected with laser instrument, as shown in Figure 2; Second step is that collimator apparatus is connected with diagnostic device, as shown in Figure 4.Details are as follows for specific works process.
The first step of collimation, as shown in Figure 2, be connected with the target chamber flange 7 of target chamber 14 by the outer drum flange 8 of collimator apparatus, target object 1 is placed in target chamber.Blind plate 12 is removably mounted on interior drum flange 13 by alignment pin, and laser instrument 10 is fixed on described blind plate 12 by fixed support 11, realizes the connection of collimator apparatus and laser instrument.The effect of alignment pin is to provide hi-Fix and reset function, and location and reset can reach 20 microns.Collimation principle of the present utility model is the high accuracy collimation principle based on laser, utilize the feature that laser direction is good, regulate the attitude of laser instrument 10, the collimation laser 17 that laser instrument 10 is launched is successively through center and the target object 1 of collimating aperture 9, image-forming component 2, intuitively visually setting up alignment fiducial line, there is principle and distinguishes in the method that this and traditional collimator apparatus utilize optical laying instrument to set up virtual reference line.
Because target object 1 is fixed, in order to make collimation laser 17 irradiation on target object 1, need the attitude adjusting collimator apparatus.First, oscillating bearing 5 is connected with urceolus 6 by bearing connection, and urceolus 6 is connected with target chamber 14 by flange, define firm banking, therefore can oscillating bearing 5 be the strong point of inner core 15, point to actuator 16 by regulating, driving inner core 15 to swing along x and y direction, x and y direction is pairwise orthogonal direction, as shown in Figure 3.The effect of corrugated tube 4 is to provide and is flexible coupling, and ensures that inner core 15 can freely swing; Secondly, the large end that one end (in Fig. 2 left end) and the imaging of inner core 15 save 3 is fixedly connected with, and when inner core 15 swings, imaging saves 3 and image-forming component 2 synchronous hunting; Again, laser instrument 10 is fixed on blind plate 12, and blind plate 12 passes through Flange joint with inner core 15 again, therefore when inner core 15 swings, collimation laser 17 also synchronous hunting, collimation laser 17 passes collimating aperture 9 and image-forming component 2 center successively, in final irradiation to target object 1 in the heart.
The second step of collimation, as shown in Figure 4, removes blind plate 12 in the lump together with the laser instrument 10 on it and laser stent 11, then diagnostic device 18 is removably mounted on interior drum flange 13 by alignment pin, realize collimator apparatus and be connected with diagnostic device 18.The Main Function of blind plate 12 is Simulation Diagnosis equipment recording surfaces, and blind plate 12 utilizes alignment pin to realize center and blind plate 12 center superposition of diagnostic device 18, thus completes the collimation of diagnostic device 18 fast after removing.Said process is enough to complete in 30 minutes usually, and collimation efficiency is at least high than prior art 3 ~ 11 times.Owing to employing alignment pin, alignment precision can reach tens micron dimensions.In addition, without the need to using optical laying instrument and multidimensional thereof to regulate support.Use collimation laser ocular demonstration datum line, therefore without the need to using optical laying instrument and multidimensional thereof to regulate support to set up virtual datum line, obviously saving resource, reducing use cost.Diagnostic device 18 contains framing camera, streak camera and pinhole camera etc.
In experiment, the object image distance of imaging system must be arranged according to the requirement of imaging amplification M.In the present embodiment, image-forming component 2 is pin hole, according to pin-hole imaging principle, by being adjusted to the length of picture joint 3, can realize the object being adjusted to picture amplification M.As shown in Figure 4, L
1for the length of imaging joint 3, L is the distance between diagnostic device 18 sensitive face and target object 1, L
2for the distance between the large end that diagnostic device 18 sensitive face and imaging save 3.Thus the object distance of imaging system is (L-(L
1+ L
2)), the image distance of imaging system is (L
1+ L
2), imaging amplification is then
（1）
Thus,
（2）
L and L
2obtain by linear measure longimetry, imaging amplification M is given in advance by requirement of experiment, therefore can calculate the length of imaging joint 3 according to formula (2), can process the imaging joint 3 of different length to mate the requirement of imaging system amplification in experiment.
In the present embodiment, after collimator apparatus is connected with diagnostic device 18, as shown in Figure 4, can by target chamber 14 vacuum state.Another effect of corrugated tube 4 keeps vacuum, and the connection of all end face of flange of collimator apparatus is that O RunddichtringO connects.Imaging joint 3 is provided with steam vent.During target chamber evacuation, imaging can be saved 3, the inside vacuum state of inner core 15 and diagnostic device 18.
In the present embodiment, point to actuator 16 and be in outside target chamber.Operator can point to actuator 16 in target field operation, the attitude of adjustment collimator apparatus.Avoid people to enter operation in target chamber 14, significantly reduce operation easier.
Embodiment 2
The present embodiment is identical with the structure of embodiment 1, and difference is, image-forming component 2 is slit.
Above embodiment is only for illustration of this utility model; and be not limitation of the utility model; the those of ordinary skill of relevant technical field; when not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
