Atom optical digital sensor chip is a new optical sensor chip with low power consumption. Multiple sensors are built into the device, providing a high degree of analog integration. Supports red/green/blue (RGB) light signal detection, ambient light (ALS) detection, proximity detection, and infrared (IR) signal and temperature information measurement. High integration features effectively reduce system costs, eliminate multiple external components, and greatly simplify the design. Atom optical digital sensor chip can be widely used in X-ray inspection fields, such as industrial X-ray inspection, medical X-ray inspection, security X-ray inspection, servo motor encoder, mobile phone communication and other fields
