LED, DLP projection screen etc., the screen can face screen or curve screens directly.When screen is curve screens, Mei Gehong
Outer laser diode is arranged in the top of screen along curved surface, and correspondingly, target and reflection platform are also along curved surface cloth
It is placed on screen.The light for being parallel to screen being emitted from infra-red laser diode again passes through target laser beam perforation, is reflecting
Speck is formed on platform, just like described in earlier in respect of figures 2, details are not described herein again.
It provides to detect whether infrared light curtain is parallel to screen as shown in figure 3, Fig. 3 is another embodiment of the present invention
The flow chart of detection method, the infrared light curtain emit infrared beam shape by multiple infra-red laser diodes being placed on screen
Into as previously described；The method includes：
S11：Reflection platform is set to the exit direction of light beam.
Such as：Reflection platform can be set to beam exit direction, on screen, such as positioned at screen edge；Or
Reflection platform can be set on beam exit direction, and except screen.In some embodiments of the invention, platform is reflected
Can be paper, backlight or lath etc..
S12：Target is set between the infra-red laser diode and reflection platform, is provided on the target multiple
Laser beam perforation, the laser beam perforation and the reflection platform are arranged so that：What infra-red laser diode was sent out is parallel to screen
Light beam can sequentially pass through laser beam perforation on target, finally form speck on the reflection platform.
S13：It whether there is speck on the detection sensor detection reflection platform, when presence and infra-red laser diode
Number different speck when, implement the adjusting to infra-red laser diode in each dimension with regulating part, until infrared swash
During the same number of speck of optical diode, judge that the light beam that the infra-red laser diode is sent out is parallel to the screen.
Component and connection relation therein involved by each steps of more than S11-S13 can be done with reference to front around Fig. 2
Description.
For example, can by target 31 multiple laser beam perforations 311,312 ..., the distance of m to screen 21 be set as one
Cause, when the light beam pass through target 31 on multiple laser beam perforations 311,312 ..., m when, it is described reflection platform 41 on formed
The speck that can be taken by thermal camera.Can will reflection platform 41 be set on beam exit direction, herein under the premise of,
Reflection platform can be for example set to the edge of screen 21 or be set to except screen 21.In some implementations of the present invention
In example, reflection platform 41 can be paper, lath or infrared light backlight etc., and the presence of the backlight is being observed convenient for human eye
The region for substantially needing to observe quickly is navigated to during thermal camera, the light intensity of backlight can be very weak, only provides an observation
Guide.
Target 31 can be pasted on the surface of screen 21 with adhesive material or be removably fixed to screen.

Enough parallel passes through laser beam perforation.Can make multiple laser beam perforations 311 on the target 31,312 ..., the number of m can be with
It is more than and/or the number of equal to every group infra-red laser diode mid-infrared laser diode, multiple laser beam perforations on target 31
311st, 312 ..., the distance between m can be set in advance, can also according to multiple infra-red laser diodes 101,
102nd, 103 ..., the distance between n is adjusted.For example, in the case where being related to multigroup infra-red laser diode, group and group
Between infra-red laser diode be spaced arrangement or it is front and rear on laser emitting direction placed in two rows of, heel row it is red
The light beam that outer laser diode is sent out is emitted from the gap between front-seat infra-red laser diode, difference group infrared laser two
The distance between adjacent infra-red laser diode may be different in pole pipe, therefore, test previous group infra-red laser diode hair
It, can be by adaptively adjusting target 31 when testing the light beam that next group of infra-red laser diode is sent out after the light beam gone out
The distance between upper multiple laser beam perforations, enable to adapt to the distance between next group of infra-red laser diode, so that
Aforementioned target can be used when being debugged to different groups of infra-red laser diodes, improve the flexibility of test, and can save
Resource-saving.
Detection sensor 51 can reflect the speck formed on platform 41 by black light with captured in real-time, if some is infrared
The light beam that laser diode is sent out forms speck on reflection platform, then illustrates that light beam has passed through the laser beam perforation on target 31,
The light beam that the infra-red laser diode is sent out is parallel to screen；On the contrary, if the light beam that some infra-red laser diode is sent out does not have
Have and form speck on reflection platform 41, then illustrate that the light beam that the infra-red laser diode is sent out is not parallel to screen 21, it can be with
The beam exit direction of the infra-red laser diode is adjusted using regulating part as shown in Figure 1.To realize the adjusting,
Infra-red laser diode can be installed on a regulating part, which can realize according to actual needs to infrared laser two
Adjusting of the pole pipe in each dimension, including infra-red laser diode displacement in all directions and angle can be adjusted；Often
The corresponding adjustable installed part of a infra-red laser diode can be fixed on a common pedestal.It is multigroup infrared sharp when being related to
During optical diode, every group of infra-red laser diode can be fixed on different pedestals, so as to it is convenient adjusted it is one group infrared
After laser diode, this group of infra-red laser diode is removed as needed, and moves into another group of infra-red laser diode.
It should be noted that although the present embodiment is parallel to infrared light curtain provided by the invention with step S11 to step S13
It is illustrated in the detection method of screen, but not because above-mentioned steps limit the detection method provided by the invention
It is fixed, that is to say, that in some cases, the action recorded in detail in the claims or step can be according to different from the present embodiment
In sequence perform and still can realize desired result.In some embodiments, multitasking and parallel place
It manages also possible or it may be advantageous.
