25 degree.The detection light beam 160 is black light, including but not limited near infrared light.The near infrared light is, for example, wavelength model
Enclose the light beam of 750nm~2000nm (nanometer).Such as, but not limited to, the detection light beam 160 is wavelength 800nm~1200nm
Near infrared light.It is understood that in other or alternate embodiments, the detection light beam 160 or collimated light
Beam or collimated light beam, such as the detection light beam of collimation can be obtained by the way that collimating element is arranged in the light emission side of detection light source 16
160, the application is not particularly limited this.
It is described detection mould group 18 be used for receives via the external object return detection light beam, and be converted to electric signal with
Realize the detection to external object.The detection mould group 18 has field of view on the first surface 101 of the protective layer 10
V.The field of view V be fingerprint detection when user's finger first surface 101 placement region, while be also first table
Face 101 is located at the part that the detection mould group 18 can receive the maximum magnitude of light beam.The first surface 101 of the protective layer 10
The surface that user's finger directly contacts when for fingerprint detection, the usually optical detection apparatus 1 or including the optical detection
The surface on the outermost side of the electronic equipment of device 1.
When carrying out fingerprint detection, the field of view V is that region of the finger to be detected is placed for user.The inspection
Survey mould group 18 be located at the protective layer 10 lower section or the display module 12 that is at least partially disposed at for detecting mould group 18
Lower section.It certainly,, usually can be by a light source in the protective layer in fingerprint detection in other or change embodiment
10 first surface position outgoing visible light corresponding with the field of view V utilizes visible light display image, is prompted with this
User places finger here and detects.Under the premise of meeting fingerprint imaging, the first surface 101 of the protective layer 10 for
The region that the region that finger is placed at family can partly overlap with the field of view V or the placement finger is detected includes
Described field of view V etc., the application is not construed as limiting this.As long as it will be understood by those skilled in the art that the field of view V or
It at least partially places the region that finger is detected, and belongs to the application protection scope.
It is reflected as shown in Fig. 2, can be the external object via the detection light beam 160 that the external object returns
Detection light beam.In this case, it can be the detection that the detection light beam 160, which transmits the predeterminable area P of protective layer 10,
Field of view V of the mould group 18 on first surface 101, i.e., the described predeterminable area P and field of view V are completely coincident.At it
He changes in embodiment, area of the area less than the field of view V of the predeterminable area P, and described predeterminable area P
Among the field of view V.Alternatively, the predeterminable area P and the part field of view V are overlapping, what both definition overlapped
Part is overlapping region Q, and the part that the two does not overlap is non-overlapping region (not indicating), and the non-overlapping region is at least partly
Or all compared with overlapping region Q closer to the detection light source 16.The area of the overlapping region Q is not less than the field of view V
40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, the 80% of area.It is possible thereby to make the detection light beam
160 at least part can transmit away in the field of view V of first surface 101 from the detection mould group 18, Jin Erjing
The external object is received by the detection mould group 18 back in the field of view V internal reflection.
It is illustrated by the citing of finger print 8 of the external object, the fingerprint 8 includes fingerprint ridge 80 and fingerprint valley
81, the finger is placed on when being detected on first surface 101, and the fingerprint ridge 80 contacts the first table of the protective layer 10
Face 101, the fingerprint valley 81 do not contact the first surface 101 of the protective layer 10, in the fingerprint valley 81 and first surface 101
Between have spacer, such as: air, grease, dirt, water etc..Because of field of view described in the detection light source 16 not face
V, it is described when carrying out fingerprint sensing to detect light beam 160 to favour the direction transmission protective layer of 101 predetermined angle of first surface
10 to irradiate the fingerprint 8, and 160 major part of detection light beam for exposing to the fingerprint ridge 80 can be reflected back toward by the inspection
Mould group 18 is surveyed to receive, and the fingerprint valley 81 between fingerprint ridge 80 can be located at the blocking of fingerprint ridge 80 for carrying out light direction and can not
It is irradiated to, so the detection mould group 18 receives the reflected detection light beam 160 of fingerprint 8 and can respectively correspond above-mentioned fingerprint
The position of ridge 80 and fingerprint valley 81 forms the light and shade grain pattern of high contrast, high light (80 image of fingerprint ridge) and most dark place
Luminance difference between (81 image of fingerprint valley) is greater than 30%, is conducive to subsequent fingerprint comparison identification.Define the detection light
Angle when beam 160 is irradiated to the first surface 101 between the first surface 101 is irradiation tiltangleθ 1, Ke Yili
Solution, the irradiation tiltangleθ 1 is smaller, and said effect is more obvious.Optionally, in the present embodiment, the irradiation inclination
The range of angle, θ 1 is 30 degree to 60 degree.
As shown in figure 3, in other or change embodiment, it can via the detection light beam 160 that the external object returns
To be to enter inside the external object after being transmitted from protective layer 10, then go out and return from the external object internal transmission
The detection light beam returned.In this case, the predeterminable area P that the detection light beam 160 transmits protective layer 10 can be with the inspection
It surveys field of view V of the mould group 18 on first surface 101 not overlap, the predeterminable area P is compared with field of view V closer to the inspection
Survey light source 16.Alternatively, the predeterminable area P can also be overlapping with the part field of view V, the overlapping region (not indicating)
Area be not more than the field of view V area 30%.It illustrates by finger print of the external object, the detection light beam
Enter finger interior after projecting the protective layer from the predeterminable area P, so that the finger can be considered illuminator.The detection
Light beam is propagated in finger interior and projects finger from the position that finger print is contacted with first surface 101, later again through described
Protective layer 10 is received at least partly display module 12 by the detection mould group 18.
Optionally, in some embodiments, the optical detection apparatus 1 is applied in an electronic equipment, the electronics
Equipment includes the middle line from its top to its bottom end, and the center of the field of view V is located on the middle line or in described
Line setting.The center of the predeterminable area P is located on the middle line or is arranged close to the middle line.The predeterminable area P is compared
