The various experiments that the present invention can give:
As shown in Figure 3, if at the fixed structure that is used to install measured object between optical imagery object lens 2 and the telecentric light light source 7 of being arranged at described in Fig. 1, be by the sinusoidal rule telecontrol equipment 5 of the generation in lower case 15 and with produce that sinusoidal rule telecontrol equipment 5 is connected and when running through the testee holding structure 3 of measuring system workbench 8 between optical imagery object lens 2 and telecentric light light source 7 and constituting, then constituted the noncontact pilot system of measuring actual object overall dimension.
The measuring principle of the noncontact pilot system of measurement actual object overall dimension shown in Figure 3 as shown in Figure 4, telecentric light light source 7 sends the light beam that is similar to " parallel ", the measured object 33 that is installed in the light beam is imaged onto on the photosurface of colored thread array CCD device 1 at image-forming objective lens 2, it produces the signal that contains testee overall dimension information under the driving action of driver, it is sent into A/D data acquisition system 21 be converted into digital signal, and deposit in the storage 22 on " multifunctional development plate 10 " by order as quick unit, send into computer system 26 through usb data transmission system 25 again, the digital signal that will be stored under control of computer software in " multifunctional development plate 10 " built-in storage 22 deposits calculator memory in.Software operation deposits the digital signal of internal memory in, compares the rate of change of adjacent picture elements numerical value, finds out the initial pixel of rate of change maximum, and it just is the border pixel of the overall dimension of object, can be designated as N
1, so can also find other border pixel, and it is designated as N
2, two border pixel difference (N
2-N
1) and pixel dimension L
0Long-pending (N
2-N
1) L
0Be the size of testee picture, consider the enlargement ratio β of optical system again, just can calculate the overall dimension D of testee
After the start, carry out dimensional measurement software, software is selected the telecentric light light source works, and the parameter setting by software interface operation line array CCD makes the signal waveform that observes satisfy test request again, just can carry out the measurement result that Survey Software obtains following formula (1).
On above-mentioned non-cpntact measurement object overall dimension experimental rig basis, utilize colored thread array CCD transducer 1, optical imagery object lens 2, telecentric light light source 7 and holding structure 3 (needing to tilt to seize on both sides by the arms testee) just to constitute the pilot system at Measuring Object angle of inclination as shown in Figure 3.This test is based on colored thread array CCD can be obtained two parallel lines surveys of usefulness object tilt as shown in Figure 6 by three photosensitive unit arrays that are arranged in parallel schematic diagram.Two any two photosensitive unit arrays that parallel horizontal line 36,37 is a colored thread array CCD among the figure, the center of testee 38 centers imaging on two photosensitive unit arrays is respectively N
1With N
2, the distance of two photosensitive unit array separation is d, then inclination alpha is
In the formula, β is the enlargement ratio of optical system.
Obviously, by the photosensitive unit array of object perpendicular to colored thread array CCD, resulting object front and rear side dividing value all equates on the photosensitive unit array of three parallel arranged, and middle position value also should equate.If object is installed on the holding structure 3 with certain tilt angle alpha, then, because the inclination of object, the boundary value and the middle position value of the object that the photosensitive unit array of three parallel arranged is measured are unequal, its difference and object tilt angle have the functional relation shown in the formula (3), measure the inclination angle that difference just can be measured object.The angle that the Measuring Object that all can be used for any two photosensitive unit arrays of colored thread array CCD transducer tilts, still, the interval of the two parallel light-sensitive cell arrays susceptibility that angle is changed far away more is high more.So, be to obtain more low-angle and more high-precision measurement mechanism with the line array CCD transducer of two separation and parallel arranged.
As shown in Figure 5, if at the fixed structure that is used to install measured object between optical imagery object lens 2 and the telecentric light light source 7 of being arranged at described in Fig. 1, be by the sinusoidal rule telecontrol equipment 5 of the generation that is positioned at lower case 15 with produce be connected tested rod member 3 ' constitute of sinusoidal rule telecontrol equipment 5, just formed non-cpntact measurement object vibration experimental system.

The measuring principle of non-cpntact measurement object vibration experimental system shown in Figure 5 is: start shooting, adjust the aperture and the focal length of optical imagery object lens earlier, choose the parameter of CCD again, especially determine the t time of integration of good CCD
cIt is the time coordinate of vibration measurement, carry out the software of non-cpntact measurement object vibration at last, testee will pressed sinusoidal regular movement (vibration of simulation object) in the light beam of telecentric light light source under the driving of dc speed-regulating motor, the optical imagery object lens all image in the position of per moment of object on the image planes of line array CCD transducer.In other words, the picture of testee will be done the motion of sinusoidal rule on the online array ccd sensor image planes, the signal of its output contains the time dependent information of object space, output signal is sent into multifunctional development plate 10, convert to after the digital signal and deliver to calculator memory by field programmable logic exploitation and expander board 11 and USB port 17.Computer software accesses the data in the internal memory earlier and does binary conversion treatment, finds out each time t
cThe center of object is abscissa, and ordinate is that the distance that object leaves the center (is that the center is the Function Y of time t
t), the drawn waveform of screen is the vibrational waveform Y of this object
tBy function

t＝Y
0sin(ωt+) (2)
In the formula, Y
0Be amplitude, φ is an initial phase, ω be angular frequency it with the pass of frequency f be ω=2 π f amplitude of being easy to calculate it, position mutually and frequency.
Sinusoidal rule telecontrol equipment 5 as shown in Figure 8 because machine shaft 34 departs from the geometric center 32 of rotary disk 33, disk 33 will be done eccentric motion, it promotes dried part 31 up-down vibration, its track be a sine.By adjusting the rotating speed of direct current machine, can adjust the frequency f of the true vibration of object, but can not adjust its amplitude, after motor speed is raised to certain speed, the amplitude that discovery is measured decreases, and illustrates that the vibration of line array CCD sensor measurement object has reached the limit.How that therefore, utilizes this device to finish to be run in the work of Measuring Object vibration applications selects CCD for use and how the problem of CCD running parameter is set.
