Description
Technical field
The invention belongs to a kind of diagonal displacement sensor in the photoelectric detection technology field and carry out the pick-up unit of sensing accuracy.
Background technology
Angular displacement sensor is a senser element of measuring physical parameters such as rotary body angular displacement, angular velocity, be widely used in the fields such as photoelectric tracking, Aero-Space, automatic technology, in order to know clearly the measuring accuracy of angular displacement sensor, before angular displacement sensor is used, must carry out actual detected to self dynamic accuracy and the static accuracy of corresponding angular sensor.
It is reported before the present invention, the checkout equipment of domestic and international diagonal displacement sensor, existing some kinds, with the most approaching prior art of the present invention be the dwell angle displacement transducer checkout equipment of Changchun Inst. of Optics and Fine Mechanics, Chinese Academy of Sciences's development, as shown in Figure 1: by angular displacement sensor 1 to be measured, polygon mirror 2, parallel light tube 3, retouch accurate indicating gauge 4, angular displacement sensor output lead 5, angular displacement sensor signal Processing electronic box 6 and form.
This checkout equipment is static aiming, and hand detects, and the precision of inefficiency, detection is low, the cost height.
In order to overcome above-mentioned shortcoming, a kind of new photoelectric detection system of ad hoc meter.
Summary of the invention
The technical problem to be solved in the present invention is: the diagonal displacement sensor carries out high-precision static state and dynamic accuracy detects.
The technical scheme of technical solution problem is: adopt polygon mirror as angle reference, laser aiming position sensing, high-speed photoelectric commutator are as receiver, and computer data acquisition is also implemented to show.
Detailed content of the present invention such as Fig. 2, Fig. 3, shown in Figure 4: by angular displacement sensor 7 to be measured, polygon mirror 8, have two photelectric receiver 9, receiver front end circuit 10, computing machine 11, display 12, typewriter 13, laser instrument 14, angular displacement sensor output cable 15 to be measured, angular displacement sensor signal output apparatus 16 to be measured that receive light pipes (D1, D2) and form.
The plane of polygon mirror 8 is perpendicular to the rotating shaft of angular displacement sensor 7 to be measured, and be installed in the rotating shaft of angular displacement sensor 7 to be measured, rotate with rotating shaft, polygon mirror 8, have two and receive light pipe (D1, D2) photelectric receiver 9, laser instrument 14 threes' position arrangement will satisfy the laser beam that laser instrument 14 is launched, beat the laser beam after the reflecting surface reflection of polygon mirror 8, receive light pipe (D1 to have two, D2) photelectric receiver 9 can receive and be as the criterion, two of photelectric receiver 9 receive light pipe (D1, D2) position, reflecting surface with respect to polygon mirror 8, it is horizontal installation, have two and receive light pipe (D1, the output terminal of photelectric receiver 9 D2) is connected with the input end of receiver front end circuit 10, the output terminal of receiver front end circuit 10 is connected with computing machine 11, the output circuit 16 of angular displacement sensor 7 to be measured is connected with computing machine 11 by output cable 15, and the output terminal of computing machine 11 is connected with typewriter 13 with display 12 respectively.
Principle of work explanation: the laser beam that laser instrument 14 is launched, after the reflecting surface reflection by polygon mirror 8, had two and received light pipe (D1, D2) photelectric receiver 9 receives, two signals that send after the reception as shown in Figure 5, transverse axis is an offset axis, Z-axis receives light pipe (D1 for having two, the amplitude of photelectric receiver 9 output signals D2), two signals intersect at the A point, homing position for tested object plane, differential comparison process is made in two signal outputs to photelectric receiver 9, export to computing machine 11 as the reference signal pulse of computing machine 11, the output signal of angular displacement sensor 7 to be measured is given computing machine 11 through signal processing circuit 16, when computing machine 11 detected the pulse signal that its intersection point of output signal A of photelectric receiver 9 sends, computing machine 11 was just gathered the angle position signal of angular position pick up 7 to be measured.Reference zero is set by computer software, and computing machine 11 calculates the angular error of angular displacement sensor 7 to be measured in real time, and the line data of going forward side by side is handled, and send display 12 real-time video data information, and by printer 13 outputs.
Good effect: because two reception light pipes of photelectric receiver can be caught target fast, make full use of the laser energy of LASER Light Source, the measuring accuracy height, realized the dynamically quick precision of diagonal displacement sensor, the measurement of rotating speed can be widely used in high-speed moving object and extract from punctual high speed information.
