In the embodiment of the present invention, the terminal 100 also includes an infrared supplementary light 40, which can be used to emit infrared light to the outside. The infrared light is reflected by the user and received by the infrared camera 10. The infrared supplementary light 40 and the application processing The device 51 can be connected through the integrated circuit bus 60, the application processor 51 can be used to enable the infrared supplementary light 40, and the infrared supplementary light 40 can also be connected with the microprocessor 52, specifically, the infrared supplementary light 40 can be connected in the microprocessor on the pulse width modulation interface (Pulse Width Modulation, PWM) 522 of the processor 52 .

Among them, the code and memory area in the trusted execution environment 511 are all controlled by the access control unit, and cannot be accessed by programs in the untrusted execution environment 512 (Rich Execution Environment, REE). Both trusted execution environments 512 can be formed in the application processor 51 .

The infrared template and the depth template may be verification templates that are entered into the terminal 100 in advance by the user before verification and pre-stored in the trusted execution environment 511 .

After the depth image is obtained, it is transmitted to the trusted execution environment 511 through the mobile industry processor interface 521 for comparison with the depth template. Wherein, the laser projected by the laser projector 20 can be infrared light, and the modulated laser pattern after the laser is projected on different materials will also be different. For example, when the laser is projected on human skin, rubber, wood and other materials, the laser is modulated The final laser pattern will be different, so the material information of the target object can also be reflected in the depth image. Only when the material is human skin, the depth image can be matched with the depth template to pass the verification.

Specifically, when the infrared image does not match the infrared template, the verification by the application processor 51 fails, and steps 03 , 04 and 05 may no longer need to be performed. When the infrared image matches the infrared template but the depth image does not match the depth template, the application processor 51 also fails the verification. When the application processor 51 fails the verification, the application processor 51 can control the display screen of the terminal 100 to display the words "verification failed, please enter again", or control the terminal 100 to generate a predetermined vibration to prompt the user that the verification fails.

The collimating element 24 collimates the laser light emitted by the light source 23 , and the laser light passes through the collimating element 24 and then passes through the diffractive optical element 25 to form a laser pattern.

The light source 23 may be a vertical cavity surface emitting laser (Vertical Cavity Surface Emitting Laser, VCSEL) or an edge-emitting laser (edge-emitting laser, EEL). In the embodiment shown in FIG. 8, the light source 23 is an edge-emitting laser, specifically , the light source 23 may be a distributed feedback laser (Distributed Feedback Laser, DFB). The light source 23 is used for emitting laser light into the receiving cavity 221 . Please refer to FIG. 9 , the light source 23 has a cylindrical shape as a whole, and an end surface of the light source 23 away from the substrate assembly 21 forms a light-emitting surface 231 . The light source 23 is fixed on the substrate assembly 21 , specifically, the light source 23 can be bonded to the substrate assembly 21 through the sealant 27 , for example, the side of the light source 23 opposite to the light-emitting surface 231 is bonded to the substrate assembly 21 .

When the laser light of the distributed feedback laser is propagating, the power gain is obtained through the feedback of the grating structure. To increase the power of the distributed feedback laser, it is necessary to increase the injection current and/or increase the length of the distributed feedback laser, because increasing the injection current will increase the power consumption of the distributed feedback laser and cause serious heating problems, so , in order to ensure that the distributed feedback laser can work normally, it is necessary to increase the length of the distributed feedback laser, resulting in the distributed feedback laser generally having a slender strip structure. When the light-emitting surface 231 of the side-emitting laser is facing the collimation element 24, the side-emitting laser is placed vertically. Since the side-emitting laser is in a slender structure, the side-emitting laser is prone to accidents such as falling, shifting or shaking.
