Osram Bidos PLPVDC 940_P_L01 3D sensing emitter module

Osram’s Bidos PLPVDC 940_P_L01 intelligent emitter module for 3D sensing allows smartphones to take high-quality images and videos with staggered depth of field. In portrait shots the person’s face remains in focus, while the background becomes blurred. Besides optimising image content, the module can also be used for 3D object recognition or augmented reality apps.

The module features a black package, a 3 W infrared VCSEL with a wavelength of 940 nm, a matching optical system, an integrated intelligent microcontroller for driving the VCSEL and a photodiode. Together, the individual components have a footprint of 3.6 x 5.46 mm. The efficiency of Osram’s VCSEL technology ensures low power consumption, and therefore facilitates not only energy management but also the integration of the component into the end device. High optical power enables the acquisition of depth information by time-of-flight (ToF) technology at a distance of up to 7 m.

In addition to optimising image content, users can also use the depth information for other functions in the smartphone, including 3D object recognition and augmented reality applications like games and interior design. Special safety mechanisms have also been integrated in the module, so that if the photodiode registers a change in the incidence of light — for example, if the optics are damaged after a fall — the current supply to the VCSEL is interrupted.
