Abstract
The invention provides a detection device for sensing biopolymer. The detection device comprises a sensing element, a light-transmitting element and a surface plasma resonance layer. The light-transmitting element is configured on the sensing element. The surface plasma resonance layer is arranged on the light-transmitting element and used for receiving the biopolymer. The light-transmitting element is arranged between the surface plasma resonance layer and the sensing element.
Description
Technical field
The present invention relates to a kind of detection device more particularly to a kind of detection devices to sense biopolymer.
Background technique
Previous identity recognizing technology is, for example, using will be transferred to paper after biological characteristic (such as: finger) pressing ink
Upper formation fingerprint graph then recycles optical scanner input computer to file or compare.Above-mentioned identification has can not
Immediately the shortcomings that processing, the demand in society now for instant authentication can not also be met.Therefore, the biology of electronic type is special
Sign identification device becomes one of the mainstream of current development in science and technology.It is however generally that biometric devices only have life
The function of object feature identification.Therefore, how to increase other functions of biometric devices, to promote living things feature recognition dress
The surcharge set is also one of the direction developed at present.
Summary of the invention
The present invention provides a kind of detection device, can sense biopolymer.
The detection device of one embodiment of the invention include light-guide device, the first reflecting element, sensing element, light-emitting component with
And surface plasmon resonance layer.Light-guide device includes top surface and the bottom surface relative to top surface.First reflecting element is set to
On the bottom surface of light-guide device.Sensing element is configured at by the bottom surface of light-guide device.Light-emitting component is to issue light beam, wherein light beam
It is reflected by the first reflecting element and is transferred to sensing element.Surface plasmon resonance layer is set on light-guide device, and to
Receive biopolymer.Light-guide device is between surface plasmon resonance layer and sensing element.
Based on above-mentioned, the detection device of one embodiment of the invention has both living things feature recognition and senses the function of biopolymer
Can, surcharge is high.
To make the foregoing features and advantages of the present invention clearer and more comprehensible, special embodiment below, and it is detailed to cooperate attached drawing to make
Carefully it is described as follows.

214 light in part E1 and light out part E2.Light beam L enters light-guide device 210 by light in part E1, and in light-guide device 210
Transmitting, forms signal beams L ' and being totally reflected at least once later, then leave leaded light by the light out part E2 of light-guide device 210
Element 210.In the present embodiment, multiple anti-reflection micro-structures 300 are equipped in the light out part E2 of light-guide device 210.
Need to first it illustrate, when signal beams L ' is entered in surrounding medium (such as: air or bubble) by light-guide device 210
When, in order to avoid the angle that light beam projects light out part E2 is greater than the cirtical angle of total reflection of light-guide device 210, and cause to answer originally
The signal beams L ' being emitted by light out part E2 is totally reflected once again again.Therefore, in the present embodiment, by having light out part E2
Multiple anti-reflection micro-structures 300, to destroy the total reflection of signal beams L '.
Specifically, each anti-reflection micro-structure 300 has sensitive area 301 and backlight area 302.In the present embodiment,
Sensitive area 301 makes the incidence angle of signal beams L ' less than the cirtical angle of total reflection of light-guide device 210, and backlight area 302 can make letter
The incidence angle of number light beam L ' is greater than the cirtical angle of total reflection.In one embodiment, backlight area 302 can be roughly parallel to signal beams L '
Main direction of travel, so that signal beams L ' be made less easily to be incident upon backlight area 302.On the other hand, sensitive area 301 is substantially
Perpendicular to the main direction of travel of light beam, and the area of sensitive area 301 can be greater than the area in backlight area 302, to make major part
Signal beams L ' all project sensitive area 301, and the signal beams L ' for projecting sensitive area 301 is also less easily all-trans
It penetrates.
Here, please continue to refer to Figure 26 to Figure 27, it should be noted that, although least a portion of stray light may project back
Light area 302, but the stray light for projecting backlight area 302 can be totally reflected, and interfere sensing without being emitted from light out part E2

Light receiving surface 240a after pass through backlight area 302 when be refracted as the biggish light beam of another angle, this light beam can be in translucent element 220
Surface 222 be totally reflected, therefore be totally reflected beam angle compared with original route come it is big, cause this light beam travelling route that can be distal to
Original route, therefore it will not be re-introduced into the light receiving surface 240a of sensing element 240, so that signal be avoided to cause showing for ghost image
As.

Examine two opposite sides of face R1, sensitive area 301 and vertical reference surface R1 form the first angle theta 1, and backlight area 302 and vertical reference
Face R1 forms the second angle theta 2.In the present embodiment, the first angle theta 1 can be greater than the second angle theta 2, to ensure most light beam
Sensitive area 301 can be projected, and will not be totally reflected again.In addition, in the present embodiment, the anti-reflection micro-structure adjacent for two
For 300, the edge of the sensitive area 301 for micro-structure 300 that one of them is anti-reflection can be with the backlight area of another anti-reflection micro-structure 300
302 coincident.That is, between two adjacent anti-reflection micro-structures 300 and not formed to connect two anti-reflection micro- knots
The bonding pad of structure 300, to be further reduced the probability that light beam is totally reflected.But in other embodiments, as long as bonding pad phase
The tilt angle of vertical reference surface R1 can be totally reflected to avoid light beam, or do not influence the travel path of light beam,
Bonding pad can be set between every two adjacent anti-reflection micro-structures 300.
