Measuring Depth and Instantaneous Velocity by Coherence of Light

Perception is hindered today by the limited performance of current sensors, and reaching a satisfactory capability requires a fusion of information from camera and other sensors. Lidwave is changing this reality and approaching active sensing from a different perspective. Lidwave’s innovative 4D sensor exploits unique coherent properties of the light to extract Instantaneous Velocity information in addition to Depth information with enhanced sensitivity. The cutting-edge and proprietary FCR™ (Finite Coherent Ranging) technology overcomes the shortcomings of traditional LiDAR and RADAR systems and provides a complete understanding of the scene dynamics without any complex computation or post-processing. Our sensor streams real-time high-quality raw data of Range, Reflectivity, and Instantaneous Velocity (Doppler) per pixel.

Lidwave's proprietary architecture enables production at scale without compromising on unmatched performance. The complex assembly of current LiDAR systems significantly increases their price and decreases their performance. One of the most challenging points is the calibration of the transmitter and the receiver which must be spatially separated to avoid crosstalk. FCR™ enables us not only to integrate the whole optical system LiDAR on a single chip but also to realize a true monostatic design in which we transmit and receive from the same pixel. To summarize, our FCR™ platform provides a cost-effective, calibration- and maintenance-free, scalable, and robust high-performance 4D-Sensor-on-a-Chip.
