Description
Technical field
The invention belongs to laser measuring technology, be specifically related to a kind of method for comprehensive detection of laser line light source and realize the system of the method.
Background technology
Laser line light source can produce redness or green visible straight line laser by what laser diode, optical element, hardware and electronic circuit formed, can be widely used in the other products such as indoor and outdoor decoration graticule location.
The line that laser line light source becomes on projection surface is laser rays, and the linearity of laser rays, width, line matter are its main indexs.
Linearity is the quantization means of the straight line laser degree of crook launched of laser line light source.
As depicted in figs. 1 and 2, the setting laser line source is perpendicular to the graticule receiving screen, and receiving screen is apart from the laser line light source O point 10m of place; Connecting two critical point A and B(A, B is the parallel lines of nadir on the graticule receiving screen), look for the solstics C apart from straight line AB on graticule; Cross the C point and be the vertical line CD of AB straight-line segment; Export center " O " point of crossing light source connects C, D 2 points, and ∠ COD represents the linearity of this graticule.
Laser rays can be crooked with form shown in Figure 1 in theory, but claim again the S line because wave shown in Figure 2 can appear in the problem laser rays of optical element, the hop of certain point as shown in Figure 3 sometimes also can occur.General measure adopts sampling or five point measurement methods at 3, can't react more really the linearity of laser rays, because wave and hop can make sample point become at random, adds many producers and adopts human eye observation to make measurement become more random.
The general two large class methods that adopt of the detection that present laser line light source line is directly spent, a kind of method of shooting that adopts is measured, utilize area array CCD as signal collecting element, be placed on the check point that needs to measure, by Video segmentation device and display, the image of a plurality of measurement points is shown in face of detection person, although this kind method intuitively but finally judge that by human eye its precision of precision is low, personal error is large.
Another kind of is to adopt line array CCD, although precision is high, on the one hand the light-sensitive surface of line array CCD is less, adopts on the other hand the mode of putting 3-5 sample point can't reflect truly that the line of laser rays directly spends situation, and not directly perceived, making in the industry, a lot of personages can't really accept this kind measuring method.
Progress along with technology, having occurred such as publication number is CN102062579A, name is called the application for a patent for invention of " a kind of detection method and device thereof of measuring laser beam position and live width with line array CCD ", and this application for a patent for invention discloses the method for utilizing line array CCD measuring laser beam position and live width.
Summary of the invention
The purpose of invention is to solve the large shortcoming with the insider is really accepted of detection personal error that present laser line light source line is directly spent.
For reaching above-mentioned purpose, invention provides a kind of method for comprehensive detection of laser line light source, comprises step: 1) divide this spread angle in the scope of 120 ° equally and form the face territory that several edge angles equate on the projection surface of this word laser module;
