The utility model is characterized in that: the two collimation laser beams are able to be directly projected outwards, or to be projected outwards after being converted into flat sector laser beams; when the collimation laser beam is projected outwards as the flat sector laser beam, the intersection line of the sector face and the cross section of a guide track is perpendicular to plane F; because the laser beam is visible, the beam is able to be observed or measured with the naked eye without assistance of other tools, thereby being very convenient for applying.
Description
Technical field:
The utility model relates to a kind of laser that can be used for range observation.
Background technology:
At present in daily life and engineering application, a lot of occasions all need to carry out the measurement of big distance, adopt conventional tool such as tape measure, roller to measure in actual use all comparatively trouble, not only waste time and energy and also measuring error big, even can't finish surveying work at some special occasions.Therefore this quasi-tradition distance measurement tools more and more can not make the user satisfy, so in recent years along with development of science and technology, laser range finder and ultrasonic range finder begin to popularize at civil area.
The advantage of ultrasonic range finder is with low cost, and volume is little in light weight.But its fatal weakness is that distance accuracy is low, mostly is positive and negative 0.5% in the nominal measuring error of the ultrasonic range finder of market sale, and promptly when measuring distance was 15m, its maximum error had positive and negative 7.5cm; And ultrasonic range finder is subject to disturb, environment temperature, humidity are changed responsive, unstable working condition.In addition because the sound wave spread angle of ultrasonic range finder is big, energy attenuation is fast, so generally can only measure the distance about 15m, and big spread angle has also proposed high requirement to test site, require promptly that the measured object area is big, acoustic reflection is good and the above clear space of 1m etc. is arranged all around, otherwise just can't measure or miss survey.All these has limited it and has popularized on a large scale in civilian field, and it mostly is used for the occasion of some space requireds and cubing at present.
Laser range finder can well solve the above-mentioned defective of ultrasonic ranging.The existing laser range finder of selling on market mostly utilizes the mistiming or the phase differential of light velocity emission and reception to measure, and its advantage is far measuring distance, precision height, stable performance, and precision is generally about positive and negative 5mm.But its shortcoming is to cost an arm and a leg, and also wants more than 5000 circles even dispose its price of minimum laser range finder, and therefore it is confined to civilian professional domain at present, also can't spread to family and use.
Comprehensively the above reaches the weak point separately that has laser range finder now at ultrasonic range finder, is necessary to be improved, to resolve the problem of cost performance.
Summary of the invention:
The purpose of this utility model is: a kind of big range observation, moderate accuracy and lower-cost laser of can be used for is provided.The utility model is achieved through the following technical solutions:
A kind of laser comprises: be provided with power supply and laser beam generating device in the housing of laser, housing is provided with light-emitting window; In the utility model, described laser beam generating device is a kind ofly to produce that two bundles are positioned at parallel plane substantially at least and angle is the laser beam generating device of 1 ° to 14 ° visible collimated laser beam.If plane F is a certain plane of parallel two collimated laser beams, plane E is the intrafascicular a branch of planes of anticipating in addition of vertical two collimation lasers.In the utility model, two collimated laser beams can directly outwards throw, and also can be converted to outwards projection after the fan-shaped flat laser beam, and the intersection of described sector and track cross-section should be perpendicular to plane F when outwards throwing in the mode of fan-shaped flat laser beam.As shown in Figure 1, the projection line of two laser on the F of plane intersects at an O, and both angles are α, and intersects at an A respectively and put B with the projection line of plane E on the F of plane.When the length of straight line A B was S, the distance L of some O and plane E can be expressed as: L=S/tg α.Observe above-mentioned formula, α is a constant after the utility model physical dimension is determined, therefore only the length S with straight line AB is relevant for tested distance L, and be the linear ratio relation between the two, so for different distance L, always can ask for the distance L of an O and plane E, that is finish the measurement of the L that adjusts the distance by the data value of measuring S.In addition,,, need not the attached of other instrument and help, use very convenient so can directly detect by an unaided eye or measure because laser beam is visible.Can be used for big range observation, moderate accuracy and lower-cost laser because the purpose of this utility model is to provide a kind of,, promptly determine one and can realize the utility model purpose 1/tg α value so must make special selection to the angle of two laser.
When angle α (0,1 °) interval in during value, the value of 1/tg α is very big, the value of 1/tg α is 572.96 during as α=0.1 °, though can try to achieve very big L this moment by measuring very little S, can realize measurement, but the measuring accuracy of S has been proposed very high requirement, otherwise can lose practical value because of the mistake of measurement result to big distance.Therefore angle α is when this interval value, can not come S is measured with common tape measure, ruler or scale, when for example α gets above-mentioned 0.1 °, the reading error of the every 1mm of appearance of its S will cause the L error of 572.96mm, so must adopt this moment special-purpose precision measurement apparatus to measure S, obviously can cause the straight line of instrument cost to rise like this, and general its adjustment when using precision measurement apparatus, process of measurement can comparatively bother, common people are difficult to use.In addition, angle α is when this interval value, also the accurate end to the α angle of instrument itself, proposed very high requirement, its corresponding 1/tg α value is respectively 636.2,572.96,520.87 when being 0.09 °, 0.1 °, 0.11 ° as α, the above error of 50S can appear in L when promptly this moment, 0.01 ° adjustment error appearred in α, suppose that this moment, the S actual measurement was 1m, then the error of L has more than the 50m, so it is very high that angle α requires the accuracy of instrument itself when this interval value, same like this can cause cost directly through raising.In sum, when α can not satisfy creation purpose of the present utility model when (0,1 °) is interval, be not suitable for the use of general civil area yet.
When angle α in (45 °, 90 °) are interval during value, S can be less than L, for the utility model, try to achieve L and do not have practical significance by measuring S this moment again, not in the discussion scope.
When angle α at (14 °, 45 °) interval in during value, the value of 1/tg α is very little, the value of 1/tg α is 1.732 during as α=30 °, though this moment, L was to the measuring error of S and insensitive to the adjustment error of the α angle of instrument itself, but when big range observation was measured, it is pretty troublesome that the measurement of S can become.When for example α gets above-mentioned 30 °, when the target about 20m is carried out range observation, the S of its required survey has tens meters approximately, this is very difficult in actual use, therefore do not possess practical significance, so in this interval, can not satisfy creation purpose of the present utility model during value as angle α to big range observation.
When angle α at [1 °, 14 °] interval in during value, the value of its 1/tg α is between 57.29 to 4.01, can take into account L this moment to the measuring error of S and to the susceptibility of instrument α angle adjustment error and the convenience of practical operation, and do not need to measure S by the precision measurement apparatus of special use, in this is interval, could well satisfy of the present utility model creation purpose during value so have only as α.
