Abstract
The utility model relates to a dynamic angular instrument, which is a light source angular instrument. The utility model is characterized in that an object lens and a light analysis lens are arranged behind a light source, a target drone which is provided with a reflecting mirror is corresponding to the light analysis lens, a high precision position transducer which is corresponding to the reflecting mirror is arranged on the focusing surface of the back of the light analysis lens, and the output angle variation signals of the position transducer is connected with a control circuit. The utility model has the advantages of simple structure, easy fabrication and convenient operation, the utility model can monitor simultaneously the angle variation of two directions, and the utility model can conduct online dynamic monitoring of registration space angle variations.
Description
The utility model belongs to optical angle measuring device.
At present, conventional optical angle gauge device as autocollimator, only can be done the unidirectional variation of Static Detection angle, also can read numerical value, the crosshair graticule all is housed in traditional optical-autocollimator, on the reception focal plane graticule and reading drum is housed, the angular instrument weak point of this kind structure is that measuring accuracy is low, complex structure, as " level meter ", can not online in real time measure, can't carry out online dynamic test to angle simultaneously.
For solving the deficiency of above test angle instrument, the purpose of this utility model provides a kind of dynamic angle testing device, structurally adopts high-precision position transducer to export corresponding analog quantity, to realize the dynamic accurately detection of target angle.
The structural design of the utility model is achieved in that this angular instrument is by light source, object lens, catoptron, beam divider and high precision position sensor are formed, its structure is at pointolite behind cylindrical mirror, the cylindrical mirror back is a beam divider, corresponding with beam divider is target, lay catoptron on the target, between beam divider and catoptron, lay object lens again, corresponding with catoptron and on the focal plane of the back side of beam divider, the high precision position sensor is housed, sensor output signal connects with control circuit, another kind of structure is for removing cylindrical mirror, light source directly by beam divider after catoptron shine on the position transducer on the focal plane of the beam divider back side.
Its principle of work is: pointolite is through living the collimated light beam that the face mirror forms, through be placed in again after the beam divider refraction on the target mirror reflects and on object lens are converged to and focus on position transducer on the focal plane of beam divider back again, at this moment, image on position transducer is rectangular straight line, position transducer is output as the one dimension angle and changes function, remove cylindrical mirror in addition, what then form on sensor is that luminous point is at x, in the y coordinate, this moment, position transducer was output as x, the function that the y two dimension angular changes, put by the corresponding simulation of position transducer output at last---to control circuit, its value is that the variation of analog quantity is the function that the target angle changes on the position transducer.
The advantage of the utility model: simple in structure, make easily, easy to use, the angle that can monitor two directions simultaneously changes, and can carry out online dynamic monitoring, except that being used for the laboratory, still can be used for some in-situ processing and need monitor the target that two angles change simultaneously.
The structure of the utility model is provided by embodiment and accompanying drawing.
Fig. 1 is the structure principle chart of dynamic angle testing device.
Its structure is by shown in Figure 1,1 is pointolite, 2 is cylindrical mirror, 3 is object lens, 4 is the catoptron on the target, 5 is beam divider, and 6 is the high-precision sensor on the focal plane, during measurement, catoptron on the target rotates with target, then on sensor, form a luminous point or a straight line, then at an x, move in the two-dimensional finite space on the y plane when being split into luminous point, sensor is exported a two dimension angular changing value, if a straight line then position transducer is expressed as one dimension angle changing value, utilized position transducer, thoroughly solved the method for target dynamic measuring angle.
