In the case that the width W of the optical element 144 and height H of translucent element 144 is definite value, light beam B ' refraction angle is bigger (also
It is that incidence angle is bigger), more it is possible to be absorbed by extinction element 142.In the present embodiment, the refractive index difference of translucent element 144
Fall in the range of 1.3 to 1.7.In addition, width W and height the H ratio of translucent element 144 are respectively fallen in the range of 2 to 20.So
And, the refractive index of translucent element 144 and the width W of translucent element 144 can be according to different design requirement (examples from height H ratios
Such as：The pitch (pitch) of image capture element 130) change, and be not limited to above-mentioned.
The wide-angle light beam from light-guide device 120 is covered using extinction element 142 (for example：Light beam B1 '), it can make only
Special angle light beam (the incident light beam of low-angle, for example：Light beam B2 ') it is transferred to image capture element 130.Via appropriate
Modulation, can make can be with 0 degree or close to 0 degree of the incident image capture element of angle by the light beam B ' of first collimator 140
130.In other words, first collimator 140 helps to will be transmitted to the beam collimation of image capture element 130.In this way, not only
Help to filter out veiling glare, additionally aid avoid from different translucent elements 144 export light beam B ' interfere the problem of, make shadow
As the capture quality-improving of capturing element 130.Therefore, biometric recognition device.It 100 can have good identification capability.Fig. 3
And it is respectively cylinder that Fig. 4, which schematically shows translucent element 144, but it is not limited.In other embodiments, translucent element
144 can also be square body, triangulo column or other polygon cylinders respectively.
According to different demands, biometric recognition device.It 100 may also include other elements.For example, biological characteristic is distinguished
Identification device 100 may also include the second collimater 170.Second collimater 170 be located at light-guide device 120 and first collimator 140 it
Between, and on light beam B ' of second collimater 170 after thing 10 to be identified effect bang path.For example, the second collimation
Device 170 is configurable on the S of surface, and the collimater 170 of light-guide device 120 and second can be by bindiny mechanism or adhesion layer (for example：
Optical cement) and be fixed together, but be not limited.
Second collimater 170 is suitable to before light beam B ' is by first collimator 140, in advance by light beam B ' collimationizations, with
Converging beam B ' the angle of divergence.In this way, probability of the light beam B ' subsequently through first collimator 140 can be increased.Fig. 5 be Fig. 1 in lead
