Driving cars become safer with Time-of-Flight systems

To satisfy the demand for increasing requirements on functionality, usability and safety in automobile applications, Beck Elektronik is offering AEC-Q102 certified VCSEL for time-of-flight systems in cars.

Beck Elektronik extends its VCSEL (Vertical Cavity Surface Emitting Laser) product portfolio with the AEC-Q102 certified PV85Q and PV88Q series from the Taiwanese manufacturer Lextar.

Due to the VCSEL typical characteristics, like extremely fast rise and fall times, very narrow optical spectrum of typically less than 1nm, and a high optical output power of up to 3.4W (CW), these parts are suitable for time-of-flight applications in cars. The wavelength of 940nm improves sunlight rejection to keep interferences as low as possible.

With the implementation of ToF systems, driving cars becomes safer and more comfortable.

The car can automatically detect the driver and adjust the seat, mirrors and interior lighting accordingly. During driving, the infotainment system can be operated with gesture control which makes distracting views to the centre console needless. Continuous monitoring of the driver can detect fatigue at an early stage and warn the driver or even allow the car to actively engage into driving.

Exterior application of ToF systems is also possible, to extend or support existing sensor systems for obstacle detection in the near field.

Both types have ceramic packages with low thermal resistance and a sophisticated diffusor lens which ensures homogenous light distribution. The PV88Q has a 3535 package, whereas the PV85Q comes in a 3532 package and incorporates a monitoring photo diode. The integrated photo diode allows monitoring of the VCSEL condition and temperature compensation of the optical output power.

Samples are available on request.
