Abstract
The utility model discloses a kind of floodlight mould groups characterized by comprising at least one laser emitter, for emitting light；At least one WLO eyeglass, the light for issuing laser emitter are diffused as uniform pattern；Shell places laser emitter and wafer level optical lens for accommodating.The utility model proposes by using WLO optical mirror slip, pattern of different shapes can be exported, and the pattern uniformity of different temperatures is more preferable, quadrangle is clear, correction distortion, therefore this technology can be applied to three-dimensional measurement, especially in mobile phone three-dimensional imaging, 3-D scanning and printing, robot vision, the fields such as security protection have wide practical use.
Description
Technical field
The utility model relates to field of camera technology, more particularly to a kind of floodlight mould group.
Background technique
With TOF (Time of flight) and structure light 3 D induction technology is increasingly mature and 3D images the fast of industry
Speed development, common floodlight mould group is far from satisfying the market demand, such as camera module and floodlight mould group cooperating, three
The fields such as dimension reconstruction, recognition of face are widely used, but are constrained to the fast heating of laser emitter, floodlight mould group
With the increase of working time, deformation occurs for common even mating plate, causes the uniformity of projected graphics poor, and quadrangle is fuzzy, distortion
The problems such as, especially sharply decline in remote effect, is not able to satisfy the demand of the applications such as 3-D scanning.
Now common floodlight mould group operating laser power consumption is all bigger, and temperature is begun to after mould group 1-2 minutes
It rises.Therefore, floodlight mould group how is made persistently to project stable pattern, so as to more preferably complete three-dimensional reconstruction, maximum limit
The problem of degree ground excavates the performance of floodlight mould group, becomes this field urgent need to resolve.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of floodlight mould group, comprising:
At least one laser emitter, for emitting light；
At least one WLO(Wafer Level Optics) eyeglass, the light for issuing laser emitter is diffused as
Uniform pattern；
Shell places laser emitter and wafer level optical lens for accommodating.
Preferably, laser emitter can be, but not limited to be laser diode (Laser Diode), vertical-cavity surface-emitting swash
Light device (Vertical Cavity Surface Emitting Laser).
Preferably, WLO eyeglass can be any one in convex lens, concavees lens or non-spherical lens or its any group
It closes.
Preferably, laser emitter and WLO eyeglass are coaxially arranged.
Compared with prior art, technical solution provided by the utility model has the advantage that
1. WLO technique, which manufactures even mating plate, can export pattern of different shapes, high production efficiency, product reliability height；
2. due to WLO eyeglass high temperature resistant, when laser emitter works long hours adstante febre, the effect of imaging substantially will not
It changes, meets application requirement；
3. using WLO eyeglass, be conducive to the volume size for reducing floodlight mould group, realize miniaturization, the micromation of equipment.
Detailed description of the invention
Fig. 1 is a kind of floodlight modular structure schematic diagram of the utility model embodiment；
In conjunction with attached drawing, following explanation is done to appended drawing reference:
1-floodlight mould group；11-laser emitters；12-WLO eyeglasses；13-shells.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, and not all embodiment.Based on the embodiments of the present invention,
Those of ordinary skill in the art's every other embodiment obtained without making creative work belongs to this
The range of utility model protection.
Fig. 1 is a kind of structural schematic diagram of floodlight mould group 1 according to shown in an embodiment of the present invention, as shown in Figure 1,
Floodlight mould group 1 includes a laser emitter 11, a WLO eyeglass 12, shell 13, and bottom is arranged in shell 13 in laser emitter 11
Portion, WLO eyeglass 12 are mounted on the top of shell 13, and laser emitter 11 and WLO eyeglass 12 is coaxially arranged.
Wherein, laser emitter 11 is selected from laser diode or vertical cavity surface emitting laser for emitting light.WLO
Eyeglass 12 is used to the light that laser emitter issues being diffused as uniform pattern, is selected from convex lens, concavees lens or aspherical
In mirror any one or any combination thereof.
The work step of floodlight mould group 1 is as follows in the present embodiment:
Step 1: being emitted beam by laser emitter 11, can be the laser of any wave band；
Step 2: laser emitter 11, which emits beam, is diffused as uniform pattern through WLO eyeglass 12.
The utility model proposes by using WLO optical mirror slip, can exporting pattern of different shapes, and different temperatures
Pattern uniformity is more preferable, and quadrangle is clear, correction distortion, therefore this technology can be applied to three-dimensional measurement, especially in mobile phone three
Dimension imaging, 3-D scanning and printing, robot vision, the fields such as security protection have wide practical use.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
