Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Figure 1 and Figure 2, be a kind of alignment system 10 that is used for locating device 100 that embodiment of the present invention provides, this alignment system 10 comprises reflection subassembly 20 and adjusts assembly 30.This locating device 100 comprises substrate 102, is arranged at the projection module 104 and the image-forming module 106 of these substrate 102 two opposite sides.This projection module 104 comprises projection optical axis 114, and this image-forming module 106 comprises imaging optical axis 116.
This reflection subassembly 20 comprises first catoptron 202 and second catoptron 204.This first catoptron 202 is positioned at the projecting light path of this projection module 104 and comprises first plane of reflection 212.114 one-tenth 45 angles of spending of this first plane of reflection 212 and this projection optical axis.
This second catoptron 204 is positioned at the reflected light path of this first catoptron 202 and is used for reflected light to this image-forming module 106.This second catoptron 204 comprises second plane of reflection 214.212 one-tenth 90 angles of spending of this second plane of reflection 214 and this first plane of reflection.
This adjustment assembly 30 comprises three screws 302,304 and 306 (following branch first screws 302 that have another name called, second screw 304 and the 3rd screw 306), these three screws 302,304 and 306 are arranged in this substrate 102 and are held in this image-forming module 106 respectively to adjust the side-play amount between this imaging optical axis 116 and this projection optical axis 114.See also Fig. 2, these three screws 302,304 and 306 and supporting of image-forming module 106 a little be equilateral triangle and distribute and to adjust uniformly to provide convenience.
During use, make projection module 104 projection centre luminous points, and reflex to this image-forming module 106, make this pipper on the imaging surface 126 of image-forming module 106, be formed into picture point 124 (ginseng Fig. 3) through this first catoptron 202 and this second catoptron 204.This pipper can be considered the luminous point of aiming at projection optical axis 114.
Relatively whether the side-play amount L between the center 136 of this imaging point 124 and this imaging surface 126 is in preset range.If not, thus then make this side-play amount L in this preset range, make side-play amount between this imaging optical axis 116 and this projection optical axis 114 in this preset range by adjusting imaging optical axis 116 that assembly 30 adjusts these image-forming modules 106.
