本发明涉及通信技术领域，尤其涉及一种光学式装置及移动终端。The invention relates to the field of communication technology, in particular to an optical device and a mobile terminal.
背景技术Background technique
随着移动通信技术的发展，智能手机以及平板电脑等移动终端越来越普及，并且已经成为人们日常生活中不可缺少的一部分。为了满足人们的要求，感光组件被逐渐被应用到移动终端上，提升了移动终端的用户体验效果，例如：用于检测移动终端所处环境光强度的光敏传感器；用于识别指纹的光学指纹传感器；以及用于检测距离的红外传感器等。With the development of mobile communication technology, mobile terminals such as smart phones and tablet computers are becoming more and more popular, and have become an indispensable part of people's daily life. In order to meet people's requirements, photosensitive components are gradually applied to mobile terminals, which improves the user experience of mobile terminals, such as: photosensitive sensors used to detect the light intensity of the environment where mobile terminals are located; optical fingerprint sensors used to identify fingerprints ; and an infrared sensor for detecting distance, etc.
但是，由于感光组件在工作时，容易接收到移动终端上的发光组件(如红外传感器和闪光灯等)发射的光线，从而使感光组件受到干扰，使其检测过程中的准确度降低。以设置距离较近的光敏传感器和红外传感器为例，当光敏传感器和红外传感器同时处于工作时，红外传感器会发射红外光，且该红外光在遇到障碍物反射后，容易射入到设置在红外传感器旁边的光敏传感器中，从而对光敏传感器检测环境光产生干扰，降低光敏传感器的检测准确度。且光敏传感器与红外传感器距离越近，干扰越强。However, when the photosensitive component is working, it is easy to receive the light emitted by the light emitting component (such as infrared sensor and flashlight) on the mobile terminal, so that the photosensitive component is disturbed and the accuracy of the detection process is reduced. Take a photosensitive sensor and an infrared sensor with a relatively close distance as an example. When the photosensitive sensor and the infrared sensor are working at the same time, the infrared sensor will emit infrared light, and the infrared light is easily injected into the The photosensitive sensor next to the infrared sensor interferes with the ambient light detected by the photosensitive sensor and reduces the detection accuracy of the photosensitive sensor. And the closer the distance between the photosensitive sensor and the infrared sensor, the stronger the interference.
可见，目前移动终端中的感光组件在检测过程中，存在因受到移动终端上的发光组件发射的光的干扰，而导致检测准确度降低的问题。It can be seen that, during the detection process of the photosensitive component in the mobile terminal, there is a problem that the detection accuracy is reduced due to the interference of the light emitted by the light emitting component on the mobile terminal.

请参见图1，图1是本发明实施例提供的一种光学式装置的结构示意图，如图1所示，光学式装置包括间隔设置的发光组件10以及感光组件20，所述发光组件10用于发出光线，所述光学式装置还包括第一偏振件30和第二偏振件40，所述第一偏振件30和所述第二偏振件40用于使入射的光线产生偏振；Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of an optical device provided by an embodiment of the present invention. As shown in FIG. 1, the optical device includes light emitting components 10 and photosensitive components 20 arranged at intervals. For emitting light, the optical device further includes a first polarizer 30 and a second polarizer 40, and the first polarizer 30 and the second polarizer 40 are used to polarize the incident light;
所述第一偏振件30相对设置于所述发光组件10的出光侧，所述第二偏振件40相对设置于所述感光组件20的入光侧，且所述第一偏振件30和所述第二偏振件40的偏振方向之间的夹角为预设角度，所述预设角度大于0°且小于180°。The first polarizer 30 is disposed opposite to the light-emitting side of the light-emitting component 10, the second polarizer 40 is relatively disposed on the light-incident side of the photosensitive component 20, and the first polarizer 30 and the The included angle between the polarization directions of the second polarizer 40 is a preset angle, and the preset angle is greater than 0° and less than 180°.
本发明实施例中，若未设置第一偏振件30和第二偏振件40，上述发光组件10发出的光线可以直接或者经过反射等入射至感光组件20中，从而对感光组件20的检测产生干扰；而上述光学式装置中设置第一偏振件30和第二偏振件40，且第一偏振件30和第二偏振件的偏振方向之间的夹角大于0°且小于180°，从而可以由发光组件10向感光组件20传播的光线中的部分或者全部光线入射至感光组件20。In the embodiment of the present invention, if the first polarizer 30 and the second polarizer 40 are not provided, the light emitted by the above-mentioned light-emitting component 10 may enter the photosensitive component 20 directly or through reflection, thereby interfering with the detection of the photosensitive component 20 and the first polarizer 30 and the second polarizer 40 are set in the above-mentioned optical device, and the angle between the polarization directions of the first polarizer 30 and the second polarizer is greater than 0 ° and less than 180 °, so that it can be obtained by Part or all of the light transmitted from the light-emitting component 10 to the photosensitive component 20 enters the photosensitive component 20 .
例如：如图1所示，发光组件10发射光线1，光线1经过第一偏振件30时产生偏振，且偏振后的光线1的偏振方向与第一偏振件30的偏振方向相同；偏振后的光线1遇到障碍物且经障碍物反射向感光组件20传播，由于感光组件20的入光侧相对设置有第二偏振件40，被反射的光线入射至第二偏振件40，若第一偏振件30和第二偏振件40的偏振方向的夹角为60°，则根据光学原理，入射至感光组件20的光线1的光强为反射的光线1的光强的1/2，从而实现部分光线1入射至感光组件20；而对于除发光组件10之外发出的外部光线2，由于外部光线2未产生偏振，第二偏振件40可以供外部光线2穿过并入射至感光组件20。For example: as shown in FIG. 1, the light emitting component 10 emits light 1, which is polarized when passing through the first polarizer 30, and the polarization direction of the polarized light 1 is the same as that of the first polarizer 30; Light 1 encounters an obstacle and is reflected by the obstacle and travels toward the photosensitive component 20. Since the second polarizer 40 is oppositely arranged on the light incident side of the photosensitive component 20, the reflected light enters the second polarizer 40. If the first polarized The angle between the polarization directions of the component 30 and the second polarizer 40 is 60°, then according to the optical principle, the light intensity of the light 1 incident on the photosensitive component 20 is 1/2 of the light intensity of the reflected light 1, thereby realizing partial The light 1 is incident on the photosensitive component 20 ; and for the external light 2 emitted by the light emitting component 10 , since the external light 2 is not polarized, the second polarizer 40 can allow the external light 2 to pass through and enter the photosensitive component 20 .
需要说明的是，上述第一偏振件30相对设置于发光组件10的出光侧，可以理解为第一偏振件30设置于发光组件10的出光侧，且发光组件10的出光侧发出的光线全部经过第一偏振件30；上述第二偏振件40相对设置于感光组件20的入光侧，可以理解为第二偏振件40设置于感光组件20的入光侧，且向感光组件20的入光侧发射的光线全部经过第二偏振件40。It should be noted that the above-mentioned first polarizer 30 is relatively arranged on the light-emitting side of the light-emitting component 10. It can be understood that the first polarizer 30 is arranged on the light-emitting side of the light-emitting component 10, and all light emitted from the light-emitting side of the light-emitting component 10 passes through The first polarizer 30; the above-mentioned second polarizer 40 is relatively arranged on the light incident side of the photosensitive component 20, it can be understood that the second polarizer 40 is arranged on the light incident side of the photosensitive component 20, and faces the light incident side of the photosensitive component 20 All emitted light passes through the second polarizer 40 .
本发明实施例中，上述发光组件10是可以发出光线的任一组件，例如：上述发光组件10可以是用于照明以及补偿拍摄亮度的闪光灯或者补光灯；或者也可以是用于检测距离的红外传感器，红外传感器可以发出红外光，并通过检测接收到的由障碍物反射回来的红外光，来实现判断发光式装置是否被遮挡以及障碍物的距离等。当然，上述发光组件10还可以是其他发光组件，在此并不进行限定。In the embodiment of the present invention, the above-mentioned light-emitting component 10 is any component that can emit light, for example: the above-mentioned light-emitting component 10 can be a flashlight or a supplementary light for illuminating and compensating for shooting brightness; or it can also be a light for detecting distance Infrared sensor, the infrared sensor can emit infrared light, and by detecting the received infrared light reflected by the obstacle, it can judge whether the light-emitting device is blocked and the distance of the obstacle.

进一步可选的，所述第一偏振件30和所述第二偏振件40的偏振方向之间的夹角为90°。当第一偏振件30和第二偏振件40的偏振方向之间的夹角为90°时，可以阻止发光组件10发射的全部光线入射至感光组件20，从而实现完全避免发光组件10发射的光线对感光组件20的干扰，进一步提升感光组件20的检测准确度。Further optionally, the included angle between the polarization directions of the first polarizer 30 and the second polarizer 40 is 90°. When the included angle between the polarization directions of the first polarizer 30 and the second polarizer 40 is 90°, all the light emitted by the light-emitting component 10 can be prevented from entering the photosensitive component 20, thereby completely avoiding the light emitted by the light-emitting component 10 The interference to the photosensitive component 20 further improves the detection accuracy of the photosensitive component 20 .
