The high-sensitivity single photon avalanche diode (SPAD) array, high-precision time-to-digital converter (TDC) array，and digital signal processor (DSP) are monolithically integrated, comprising background light suppression, noise reduction, and data compression algorithms.

With a vertical cavity surface emitting laser (VCSEL) array, miniaturized modules can be implemented, based on the direct time-of-flight (dToF) technique, to achieve the mobile terminal 3D perception with miniaturization and low-power features.

Augmented reality (AR), virtual reality (VR), digital room, intelligent street view, intelligent home, etc.

The large scale single photon avalanche diode (SPAD）array, high precision time-to-digital converter (TDC) array, and high-speed serial interface are monolithically integrated.

With the laser diode (LD) or vertical cavity surface emitting laser (VCSEL) array, the high-resolution 3D detection can be achieved of a large field-of-view over a long distance based on the direct time-of-flight (dToF) technique and temporal/spatial statistics method, with the aid of various algorithms including background light suppression, noise reduction, and data compression, etc.

Automatic Driving, Auxiliary Driving, Confined Space Transport, Industrial Automation, etc.

Multi-channel SiPM is adopted as a front-end photoelectronic sensor, which is monolithically integrated or flexibly cooperates with high speed low noise transimpedance amplifier (TIA), high precision time-to-digital converter (TDC), and high-speed ADC. Thus, the level of integration and uniformity of the front-end circuit are greatly improved, and the volume, power consumption, and cost of the rotating scanner or MEMS based LiDAR are significantly reduced.
