On June 28, 2016 world conference on mobile communications (MWC) global terminal summit held in Shanghai. Osram opto semiconductors, vice President, infrared business general manager Bodo Ischebeck to attend and make power mobile technology "optical sensor" keynote address. In his speech, Bodo Ischebeck carrying mobile terminal equipment, optical sensing technology is introduced in the biological recognition, biological sensing, VR/AR and 3 d sensing in the field of new applications and development prospects.
Biometric systems used in mobile equipment opportunities and challenges
Bodo Ischebeck in LEDsinde mentioned in an interview, infrared light with mobile devices such as mobile phones and tablet computers used in iris recognition and face recognition become a new trend.
Last year Japan's Fujitsu launched the world's first iris scanning unlock the phone, this phone with osram opto semiconductors production of infrared light-emitting diode (IRLED), can be more safely unlock online banking, online shopping the application of high security level.
Because each person's iris feature has its uniqueness, so iris recognition technology compared with fingerprint identification technology of security protection grade is higher, therefore become mobile devices such as mobile phones and tablet computers to unlock new way.
Biometrics bright prospects, but Bodo Ischebeck also mentioned at the same time, the cost of the iris recognition system on the high side, the main is not infrared LED device is too expensive, but the camera system!
Because of the existing camera in order to avoid too much noise affect the imaging quality, so will block out 810 nm infrared light. Therefore the existing iris recognition system need another sensor independently infrared camera. But with the progress of technology, system factory will strive to infrared sensor integration into existing camera module to reduce the overall cost, but still need some time to overcome these technical challenge.
In addition to higher cost, Bodo Ischebeck emphasize impress application is the most important key factors of consumers. Especially for personal data confidential to demand higher Mobile payment, Mobile payment), it must be a killer application. But at this stage of the mobile payment, it seems, are still not mature enough, infrastructure construction has not been completed. So you need to watch network operators or brand equipment factory can accelerate launch related applications.
At present many handset vendors have to go for iris recognition. Especially osram samsung mobile phone has been in India's government was observed in the import of carrying the iris recognition of mobile phones. Mainly because the public sector for confidential data need to be more protective measures. Although the iris recognition has been adopted the number of mobile phone is still limited, but the application prospect of optimism.
Optical sensing technology to realize virtual reality application
In addition, in the field of augmented reality and virtual reality, much attention has been paid to the optical sensing technology also provides the necessary technical support. In games, VR glasses and a head-mounted display with infrared leds and infrared tracking technology, developed a tracking system that can track the user's eye movement and direction of human movement.
At the same time, the focus of Rendering technique (Foveated Rendering) won new applications for eye tracking system, become a VR on the market one of the most popular hot technology. Through optical sensor, the rendering technique for eyes focus target is analyzed, the focus position to provide high resolution, the other parts with lower resolution, which reduces the VR burden of image processing, mobile devices, and enables the VR devices to provide more rapid, accurate and low latency tracking rendering.
Bodo Ischebeck also emphasized, although at this stage of sensing technology principle of VR operators are not the same, but the optical sensor is an indispensable key components, the proportion of cost of VR system is relatively high. So future VR vendors will also to continuously optimize the system, including the integration of more features and further reduce the cost. And osram is the only way to provide all of photoelectric solutions to the VR with AR system manufacturers.
From the light emitting component (Emitter), the receiving component (Detector), and even IR laser, through these key components can support location Tracking (Position Decetion), Gesture sensor (Gesture Recognition), image Projection (the Projection), eye-tracking (Eye Tracking) such as technology. Now osram has spent a lot of engineering and r&d manpower to support the VR system manufacturers, and can provide the calibrated, efficiency optimization of optical sensing component to the customer.
VR glasses and a head-mounted display with infrared leds and infrared tracking technology, developed a tracking system that can track the user's eye movement and human movement direction, brought more natural and fluent for VR users gaming experience.
Osram opto semiconductors aggressive expansion, the pursuit of long-term growth momentum
"Optical sensors have been widely carry on phones, tablets and other mobile devices, for today's mobile devices, optical sensor is no longer an option, but a must option," Bodo Ischebeck is introduced.
"Osram opto semiconductors devotes to provide the most appropriate for the mobile device components and a variety of solutions, hope that the future can achieve more advanced applications. At the same time in order to meet the needs of the market and the continuous expansion of production capacity. At the same time also invested a lot of research and development resources, including recruitment in China a lot of research and development engineers, marketing and business personnel, providing technical support for customers.
Osram is a one hundred - year - old company, we are actively seeking growth momentum, and hope to be able to sustainable development, this is also our long-term commitment to customers. "
