This technology is indispensable to the trillion-dollar advanced driver assistance market and is the key to improving the performance of LiDAR and ADAS!

The characteristics of SPAD (Single Photon Avalanche Diode) are closely related to many functions of ADAS (Advanced Driver Assistance System).

Here are some key aspects of how SPAD characteristics support ADAS functionality:

High sensitivity and low light performance

SPAD sensors have extremely high sensitivity and can detect single photons, which enables them to work reliably in low-light environments such as night driving. This is especially important for the following ADAS functions:

Night Vision System: Helps the driver see the road clearly at night or in low light conditions.

Automatic High Beam Control: Automatically adjusts high and low beams based on road conditions and oncoming vehicles.

High-speed detection and low latency

SPADs can quickly detect and respond to optical signals, which is very important for ADAS functions that require high real-time performance. This includes:

Automatic Emergency Braking (AEB): When there is an obstacle ahead, the system can quickly detect and automatically initiate braking.

Lane Keeping Assist (LKA): Instantly detects lane markings and helps the driver stay in the lane.

High-precision distance measurement

SPAD technology provides high-precision distance measurement in LiDAR (Light Detection and Ranging) applications, which is critical for the following ADAS functions:

Adaptive Cruise Control (ACC): Automatically adjusts vehicle speed based on the distance to the vehicle ahead to maintain a safe distance.

Blind Spot Detection: Accurately monitors the blind spot areas around the vehicle and alerts the driver to vehicles that cannot be seen.

High resolution and multi-object detection

SPAD technology is able to detect multiple objects at high resolution, which is very beneficial for the following ADAS functions:

Surround View Monitoring System: Provides 360-degree surround view to help the driver fully understand the vehicle's surroundings when parking and driving at low speeds.

Pedestrian and Bicycle Detection: Accurately identify and track pedestrians and bicycles to improve safety in urban driving.

Anti-interference ability

The SPAD sensor has good anti-interference ability against ambient light interference, which helps to improve the reliability of the ADAS system under various driving conditions.
