Detailed description of the invention
It is described below and illustrates the exemplary of the present invention.In order to clear and accurate, described exemplary discussed below can include preferred step, method and feature, those of ordinary skill in the art are not it will be appreciated that these preferred steps, method and feature are the essential conditions being within the scope of the present invention.
The working face standard for calibrating working face attitude on photometer bench shown in Fig. 1, it is characterised in that include main body (1) and cross hair pipe (2)；Described cross hair pipe (2) is hollow pipe and can be placed in assembling in described main body (1)；Two end faces of described cross hair pipe (2) are each provided with crosshair (3)；The line of two crosshairs (3) is parallel with the axis of described cross hair pipe (2), preferably conllinear；Described main body (1) has the front surface (5) of the axis being perpendicular to described cross hair pipe (2), and described working face (6) is limited by two fine rules (4) being located at described main body (1) the right and left.
As in figure 2 it is shown, when utilizing the spatial attitude of device work in described standard calibration optical radiation measurement, described working face standard (15) is placed on the coaster (11) being positioned at photometer bench (12).Coaster (11) is in addition to can moving along photometer bench (12), and also four degree of freedom can adjust, and the most described working face standard (15) can carry out the position adjustment of five degree of freedom.Adjusting means in regulation coaster (11) so that the working face (6) of described standard is perpendicular to the optical axial of described photometer bench (12)；Projecting lamp (10) and marking plate (14) it is respectively provided with outside the both sides of described photometer bench (12)；nullOpen described projecting lamp (10)，The position of regulation projecting lamp (10) and marking plate (14) makes being overlapped by described projecting lamp (10) of two fine rules (4) of described working face standard (15) in the upper projection formed of described marking plate (14)、Clearly，And at the upper described location of projection of described marking plate (14), markings are set，Keep the projected position i.e. spatial attitude of working face，Fixing projecting lamp (10) and the position of marking plate (14)，In test afterwards，As long as keeping projecting lamp (10) and the invariant position of marking plate (14)，Just it is no longer necessary to use working face standard (15)，Only device work to be calibrated need to be replaced described working face standard (15)，And the position adjusting its working face makes the consistent with the above-mentioned markings on marking plate (14) (or parallel) in the upper projection formed of marking plate (14) by projecting lamp (10) of its working face，The working face of device work the most to be calibrated is i.e. vertical with the axis of photometer bench (12).Specifically, the described working face standard (15) being placed on described photometer bench (12) can be replaced with detector to be calibrated, regulate the described detector to be calibrated position on described photometer bench (12) and attitude, the projection formed on described marking plate (14) by described projecting lamp (10) of the working face of school detector is treated and in step S300 the upper markings arranged of described marking plate (14) parallel (preferably overlapping) described in making, so that the working face of described detector to be calibrated is vertical with the optical axial of described photometer bench (12), again the center treating school detector is adjusted to consistent with the center of cross hair pipe, i.e. complete the pose adjustment of detector.
In some cases, cross hair pipe (2) is placed in the circular port of main body (1)；The spatial attitude of working face standard (15) is adjusted by the position regulator on coaster (11), the forward and backward cross hair (3) being made cross hair pipe (2) by level gauge (13) observation is all consistent with the optical axial of photometer bench (12), so in the axis of cross hair pipe (2) and main body (1), the axis of institute's making circular hole is just the most consistent with the axis of photometer bench (12), and the plane that now two fine rules (4) on the front surface (5) of standard are limited is vertical with the axis of photometer bench (12).
In some cases, described main body (1) has the groove vertical and parallel with described working face (5) with the axis of described cross hair pipe (2), the through described main body of described groove level (1) makes main body (1) in " [" type, described two respective upper and lower two ends of fine rule (4) are individually fixed in the upper edge at described groove two ends and lower edge.So be positioned at photometer bench (12) side projecting lamp (10) can easily by the projection of two fine rules (4) of working face standard (15) that is positioned on photometer bench (12) on the marking plate (14) being positioned at photometer bench (12) opposite side.
In some cases, a circular hole is opened in main body (1), cross hair pipe (2) can be laid in circular port, " E " shape it is shaped like after assembling fork fiber tube (2), circular port closely cooperates with cross hair pipe (2), is ensured that by machining the axis of circular port is vertical with the front surface of main body (1) (5)；Before and after cross hair pipe (2), end face is transparent and has crosshair (3), when cross hair pipe (2) is placed in the circular port of main body (1), the axis that two crosshairs (3) are constituted is consistent with the axis of circular port in main body；Two fine rules (4) are laid on the front surface (5) of main body (1), it is close on front surface (5), and the plane (6) that two fine rules (4) are limited is parallel with the front surface of main body (1) (5).
In some cases, described fine rule (4) is nylon wire, a diameter of 0.1-1mm, preferably 0.2-0.5mm.End face preferably lucite be carved with crosshair before and after described cross hair pipe (2), or directly mount two nylon wires and constitute crosshairs.The line at the center (cross hair intersection point) of described crosshair (3) is consistent with the axis of cross hair pipe, and consistent with the axis of institute's making circular hole in main body.
Using two plumb lines compositions to be perpendicular to the plane of photometer bench axis with common method, or compare by the method for two optical axis orthogonal level gauge calibration operation planes, described standard uses more convenient, and work efficiency is higher.
Patent of the present invention is described above by the mode illustrated.It is understood, however, that the present invention is not limited only to these detailed description of the invention.Those of ordinary skill can carry out various amendment or variation to the present invention, and these amendments and variation broadly fall into protection scope of the present invention.
