company blog about VisionICs VI4331 3D dToF Imaging Sensor: A Powerful New Tool for Deep Perception, Empowering Machine Vision and AR/VR

Shenzhen Mingjiada Electronics Co., Ltd. offers long-term supply of brand-new, genuine VisionICs (CoreVision) VI4331 direct time-of-flight (dToF) imaging sensors from stock and provides premium buyback services. This product serves as a highly integrated core component in the field of 3D depth sensing, specifically engineered for applications such as robotic navigation and obstacle avoidance, 3D machine vision, and security monitoring. With its core advantages of high resolution, high precision, low power consumption, and anti-interference capabilities, it has become a critical sensing component in intelligent robotics, industrial automation, and smart security sectors.

VI4331 Product Overview

The VI4331 is a direct time-of-flight (ToF) imaging sensor integrating a 240x96 single-photon avalanche photodiode (SPAD) pixel array, front-end time-to-digital converter (TDC), and depth DSP processor. Combined with a pulsed laser emitter, this sensor delivers a 240x96 depth image. The sensor provides a MIPI CSI-2 interface supporting both histogram and DSP mode pixel data formats. Additionally, it integrates an illumination controller and four laser triggers to support addressable VCSEL configurations for up to four illumination channels. The sensor incorporates a microcontroller (MCU) for implementing software patches and enhancing programmability. It also integrates an SPI interface, enabling configuration of downstream laser diode drivers (LDDs) within ToF systems and allowing direct sensor access to module calibration data and firmware code stored in module memory (e.g., EEPROM or Flash).
