Description
Technical field
This utility model is related to optical system and determines field, and in particular to photoelectricity school axle instrument.
Background technology
In modern military electro-optical system, no longer it is the military issue weapons equipment for only existing single spectral coverage, but defines collection
Visible ray, laser and the infrared multispectral integrated application being integrated.Therefore, Display Aim Taking on TV Set axle in electro-optical system, infrared sight
Take aim at axle, that the concordance of laser ranging transmitting many optical axises such as optical axis is just directly determined is accurate with acquisition to target information detection
Degree.
Centered optical system is usually axisymmetric, that is, have a public axis, commonly referred to optical axis.Optical axis is parallel
Property, as the term suggests, that is, the collimation having between two groups or more centered optical system.Many centered optical systems typically exist
Test indoor detection claims plain shaft parallelism or parallelism of optical axis when debugging, on large-scale armament systems or weaponry, due to many
Road optical system will aim at same target at a distance, so being also called light axis consistency.
During many optical axis system optical axis collimations are calibrated, the large-caliber off-axis parabolic in calibrating installation is needed
Face collimator can provide collimation good collimated light beam, and the only collimation of the collimated light beam of collimator is good, could be with
The plain shaft parallelism of the high accuracy measurement photovoltaic of comparison.The key for providing the good collimated light beam of collimation seeks to a mesh
Mark leather is accurately positioned at the focal plane of large-caliber off-axis parabola collimator.Target to focus error less, there is provided flat
The collimation of row light beam is better, and the accuracy for measuring plain shaft parallelism is higher.Therefore the error size that target is focused will
Affect the calibration accuracy of final calibrating installation.It is many optical axis system optical axis collimation collimation techniques that target is strangled and focuses technology
In a key technology.
Many plain shaft parallelisms are the problems that high accuracy electro-optical equipment institute must be faced, the remote precision strike of weapon
Higher requirement is constantly proposed, the measure of plain shaft parallelism, the research association of technique is improved and is stayed away from stagnation, and the calibration skill of light uranium
The research of art is also never stagnated.With the development of automatic technology, the collimation technique of many light uranium also can be towards less measurement
The calibrating direction development of error.
For many optical axis armament systems, a main source of error is laser beam axis and TV axle or swashs
Imbalance between light optical axis and infrared optical axis.Collimation between optical axis is a very important individual character of many optical axis armament systems
Can index.In addition, axle instrument bore bigger versatility in school is stronger, focal length is bigger, and accuracy is higher.
The determination of focal surface of collimator tube position generally has following several method：Remote thing adjustment method, adjustable preset lenses method, three pipes
Method, pentaprism method, knife method and interferometer mode etc..
Above several method, remote thing adjustment method are typically chosen 1000 times that the distance of target is about objective focal length.Due to remote
The target of distance is affected and image blur by atmospheric agitation and dust, and the distance being therefore typically chosen is within 1000m.So
One, this method is only suitable to the determination of the focal surface of collimator tube position of shorter focal length (f ＜ 1000).
Adjustable preset lenses method is suitable for the calibration of the less focal surface of collimator tube of relative aperture because the bore of preset lenses than
Collimator bore is big.
Three tube method need three specification identical collimators, and this is also relatively suitable for for small-sized collimator, for
Heavy caliber collimator, not only cost is high, and heavy.The heavy caliber collimator of three same sizes of processing, is less existing
Real.
Pentaprism method need equipment simple, it is thus only necessary to one through instrument and a pentaprism and a guide rail,
Simple to operate, but for large-caliber off-axis paraboloidal mirror just unsuitable for.The focal length one of large-caliber off-axis paraboloidal mirror
As long, and the ratio of the focal length and bore of off axis paraboloidal mirror, typically than larger, the now sensitivity of pentaprism method is not
Height, focuses that error ratio is larger, and the high accuracy for being unsatisfactory for this problem is required.
The equipment that knife method needs is simple, it is only necessary to a table blade instrument and a high accuracy plane mirror,
It is quick on the draw, focuses accuracy height, simple to operate, but knife method is the side that a kind of human eye is directly observed and reached a conclusion
Method, different people feel different, and the position of the focus for finding can slightly have difference.Additionally, the use of knife is at the beginning of for one
More difficult for scholar, the phenomenon for observing knife needs a long training process, focused using knife method
When, need a veteran knife user of service to observe and operate.Rough using knife method in this problem
Focus.
It is very high that interferometer mode focuses accuracy, however it is necessary that interferometer, high accuracy plane mirror and one five
Dimension adjustment frame.It is quick on the draw, focuses accuracy at a relatively high.
