Specific implementation mode
The present invention is described in detail by specific embodiment below in conjunction with the accompanying drawings, for a better understanding of this hair It is bright, but following embodiments are not intended to limit the scope of the invention.
The present invention proposes a kind of perfect heat-dissipating and small chip flush mounting.It will be with depth in explanation below It is illustrated for the projection module of degree camera, but is not meant to that this scheme is only capable of applying in depth camera, Ren Heqi Every direct or indirect utilization program is intended to be included in protection scope of the present invention in his device.
Depth camera
Depth camera side schematic view shown in FIG. 1 based on structure light.10 main building block of depth camera has laser Module 13, acquisition module 14, mainboard 12 and processor 11 are projected, RGB camera 16 is further provided in some depth cameras.Swash Light projection module 13, acquisition module 14 and RGB camera 16 are generally mounted in the same depth camera plane, and in same One baseline, each module or camera correspond to a light portal 17.Usually, processor 11 is integrated on mainboard 12, And laser projection module 13 is connect by interface 15 with mainboard with collection model 14, the interface is in one embodiment FPC interfaces.Wherein, laser projection module is for projecting encoded structured light patterns, collection model acquisition into object space By the processing of processor to obtain the depth image of object space after to the structure light image.In one embodiment, it ties Structure light image is infrared speckle pattern, and pattern is relatively uniform with distribution of particles but with very high local irrelevance, here Local irrelevance refer in pattern that each sub-regions all have higher uniqueness.Corresponding acquisition module 14 is to correspond to Infrared camera.
The chief component of depth camera based on time flight method principle (TOF) is also projection module and acquisition mould Group, it projects module for emitting the light pulse clocked, acquisition module acquisition unlike the depth camera of structure light principle Can be obtained by the flight time of light in space after to the light pulse, recycle processor calculate corresponding spatial point away from From.
Depth camera single at present is mostly to pass through the data-interfaces such as USB as independent peripheral hardware since volume is larger With the information such as the depth for connecting, and being obtained such as other equipment such as computer, mobile phone be transferred to other equipment carry out it is further Processing.It is more and more extensive with the application of depth camera, depth camera and other equipment are integrated, integrates and will be future Developing direction.The mainboard, processor and computer cell phone etc. of depth camera can be set at the integrated aspect of mainboard and processor Standby mainboard, processor are integrated;In the integrated aspect of acquisition module and laser projection module, at present large scale equipments such as computer There is relevant scheme, however for micromodule equipments such as mobile phones, only small laser projection module can just be met the requirements, separately Outside since the power consumption of laser projection is larger, fever is more, possessing higher thermal diffusivity is also highly desirable.The weight of the present invention Point will propose a kind of chip flush mounting that can be used in depth camera projection module possessing high-cooling property and small size, But it is not limited to depth camera.Next laser projection module is described in detail in scheme according to an embodiment of the invention.
Laser projection module
Fig. 2 is a kind of embodiment of laser projection module 13 in Fig. 1.The projection module 13 include pedestal 131, light source 132, Upper and lower microscope base 133 and 134, lens 135 and diffraction optical element (DOE) 136.The light beam that light source 132 is sent out is accurate through lens 135 Emitted from DOE136 into space after straight, usually lens 135 are between light source 132 and diffraction optical element 136, lens The distance between 135 and light source 132 are preferably equal to the focal length of lens.Lens can also be integrated into DOE in other embodiments One optical element.Can be connected through a screw thread between upper and lower microscope base can also be in direct contact connection, and preceding kind of mode is conveniently adjusted Focal length, then kind mode, which is adjusted, is more troublesome, but optical axis can also be adjusted other than it can focus.131 1 side of pedestal Face requires enough hardness to support light source, has on the other hand also needed to higher thermal diffusivity.
The size of the volume influence entire depth camera of laser projection module, and the wherein size of light source 132 and pedestal 131 It is then an important factor for influencing laser projection modular volume.In the selection of light source, vertical cavity surface laser emitter (VCSEL) is gathered around Have the advantages that small, the light source angle of departure is small, the good light source that can be used as projection module of stability is to reduce whole body Product.Next VCSEL and its array chip are illustrated first, secondly the embedded equipment of itself and pedestal 131 is explained It states.
VCSEL array
Fig. 3 is the structural schematic diagram of single VCSEL.In figure 3,301 be single VCSEL, and usually, VCSEL's is active Layer 305 is in centre, and what is connect with active layer is limiting layer 306, and the effect of limiting layer is for controlling light field and electric current to realize There is the semiconductor mirror 304 and 307 of p-type and N-type at control to laser shape etc., active layer both ends, speculum 307 it is another Side is top electrodes 308 (poles P, anode), and the side of speculum 304 is semiconductor substrate 303 and bottom electrode 302 respectively (poles N, cathode).
Shown in Fig. 4 is VCSEL array schematic diagram.When application requirement is not achieved in power of single VCSEL light source etc., lead to It crosses multiple VCSEL403 being arranged in an array manner in the same semiconductor substrate 402 and can improve light source power, in addition Manufacture efficiency can also be greatly improved by manufacturing multiple VCSEL light sources simultaneously in the same semiconductor substrate.VCSEL array chip 401 can reach the scale of wafer scale at present, you can in 1mm2Chip on arrange hundreds and thousands of a VCSEL light sources.To light The control in source can have a different patterns, and all VCSEL light sources are in synchronized control opening and close on chip, alternatively, chip On VCSEL by independent or grouping control to generate different illumination density.In some embodiments, using the first pattern, That is VCSEL light source all on chip is in synchronized control opening and closes.In further embodiments, second of mould may be used Formula, i.e. VCSEL on chip are by independent or grouping control to generate different illumination density.
The form of VCSEL403 and arrangement according to specific application demand can there are many, such as be uniformly regularly arranged or Person carries out irregular alignment with certain uncorrelated pattern.The shape of single VCSEL, area can not also be identical.Formal Randomization can bring the reduction of manufacture efficiency.In some embodiments, VCSEL403 is uniformly regularly arranged serves as a contrast in semiconductor On bottom 402, in further embodiments, according to specific application demand, VCSEL403 is irregular with certain uncorrelated pattern It is arranged in semiconductor substrate 402.
In some embodiments, VCSEL chips can also be packaged by special purposes, be similar to the CPU etc. of computer Positive and negative anodes are connect in the same side with the external world by chip by being connected to pin.For depth camera embodiment of the present invention For, it is small due to requiring, thus preferably processing mode is directly to be placed in unencapsulated VCSEL semiconductor slice chips On pedestal 131.Usually, the bottom cathode connection of chip, the connection of top anode.Core will be sliced with VCSEL in the following description It is illustrated for piece, it will be appreciated that encapsulation chip is also contained in protection scope of the present invention.
