Consumers anxiously await the broad introduction of affordable 3D smartphone cameras for mobile applications, as well as industry breakthroughs like autonomous vehicles, which are guided by LIDAR (Light Detection and Ranging) sensors.
Cutting-edge technologies such as LIDAR and 3D camera imaging rely on the accurate measurement of extremely weak light intensities.
The modern detectors, such as single photon avalanche diodes (SPAD) is very sensitive and can detect even smallest portion of light - a single photon.
SPAD has one critical drawback: it operates at high voltage. When integrating a SPAD sensor into mobile devices, a high voltage is generated on the chip, requiring power-hungry and area-consuming circuits. High voltage also complicates the array building.
ActLight’s Dynamic Photodiode (DPD) technology offers a technological breakthrough in light sensing. DPD can combine single-photon sensitivity with low operational voltage.
