Tiny VCEL suitable for 3D sensing applications

ams OSRAM expands its 3D sensing portfolio with four newvcsel模块. The number of applications that utilize 3D sensing technology continues to increase: From the detection of the surroundings for robots to avoid collisions to the unlocking of smartphones via facial recognition. But 3D sensing also plays an important role in augmented and virtual reality (AR/VR) glasses. Thanks to components like Bidos P2433 Q from ams OSRAM, various gestures can be reliably captured, raising the interaction between users and AR/VR glasses to a new level. The compact package also allows custom-ers-specific design flexibility.

For augmented and virtual reality devices, as well as other 3D world-facing applications, the focus is on maximum user experience combined with compact and lightweight design. In the 3D sensing market, Vertical Cavity Surface Emitting Lasers (VCSEL) have a huge impact due to their good beam quality, cost efficiency, and simple design.

BidoS P2433 Q有四种不同的版本，包括两个不同的照明领域和两个输出功率电平。尺寸为3.3 mm x 2.4 mm的基于VCSEL的模块适用于使用飞行时间（TOF）测量的3D感测应用，这需要均匀的场景照明。由于它们的波长为940 nm，所有模块也没有红色辉光效应，这被人眼所感知为令人不安的闪烁。

The two higher power modules with 6.5 watts use dual-junction VCSELs for outstanding performance and efficiency of up to 45%. In addition, a photodiode monitoring system is integrated into the module as a special protection mechanism for eye safety. If the photodiode registers a change in the incidence of light – for example, if the optics are damaged – the current supply to the VCSEL is interrupted.

除了3D手势识别外，还可以在工业机器人中使用障碍物避免和虚拟击剑，或在智能门锁或销售点支付终端的3D面部认证系统中使用。
