The University of Tokyo pointed out: “The uniqueness of this setup is that the laser pointer beam is converted into white light with high efficiency, thereby reducing the heat of the ADB system.” The Tokyo team arranged an actuator in its ADB architecture to allow the scanner to perform Large-angle horizontal and vertical deflection, so as to realize the two-dimensional scanning of the headlight beam, and the mode of the mechanism is also designed so that it will not react to low-frequency noise (such as noise produced by other vehicles).
In the test, the ADB system was integrated into an assembled headlight block and installed on the right side of the vehicle. As a proof of concept, two MEMS-ADB modules were used to cover high-illuminance and low-illuminance areas, although it will be the ultimate goal that a MEMS module can cover both areas at the same time. A camera and image recognition function are installed to explain road conditions and adjust ADB accordingly.
Experiments show that the system provides better visibility for the driver, especially when seeing pedestrians. It can visualize pedestrians standing next to oncoming vehicles while adjusting the lights to avoid dizziness for other drivers. The researcher said: We have taken another step towards risk-free driving. In the future, this system can find its place in the autonomous driving technology of intelligent transportation systems.
The researchers said that under current conditions, the demand for data traffic is increasing exponentially. Ultrafast pulsed green laser pointer based on resonators and graphene work at ultra-high speeds and have allowable tuning characteristics. Changing data processing requirements.
Graphene, as a new material in which carbon atoms are closely packed into a single-layer two-dimensional honeycomb lattice structure, is a quasi-two-dimensional material with a thickness of only one atomic layer, also called monoatomic layer graphite. Although graphene is widely used, the current domestic research on graphene is still in the stage of vigorous research and development, which is not enough to transform scientific research results into products. I hope that within a few years, we can see new changes in graphene in the laser technology industry.
