Scanning CMOS LiDAR Sensor

SolidView’s two solid-state sensors (Sauron I & Sauron II) offer reliable TOF measurements even in noisy environments with strong IF.
Our sensor exhibits essential features, including multi-event recording, on-chip histogramming, and inter-LiDAR IF filtering in a single chip. Therefore, SolidView’s sensor can be successfully applicable to the self-driving cars that operate in noisy environments and IF.

Key Features

  • Long-range detection: 48 m (Sauron I) / 128 m (Sauron II)

  • On-chip Histogramming for noise-free depth imaging

  • Multi-event recording per ToF measurement for noise-free depth imaging

  • Power consumption < 180 mW

Flash CMOS LiDAR Sensor

SolidVue’s CMOS solid-state flash-type LiDAR sensor (Gandalf) provides a reliable 3-D depth map of target objects placed within a 20-m distance. Each pixel incorporates a zoom histogramming time-to-digital converter (TDC) to combine a coarse time delay measurement with a fine extraction of phase difference, extending the TDC resolution from 7-b to 13-b without generating a GHz-level clock signal.

The coarse TDC decides only 1-b of the time-of-flight (ToF) value by the binary search manner, eliminating large memories for histogramming and occupying a small area. Since all pixels extract depth information simultaneously, our LiDAR doesn’t require any scanning equipment, making it suitable for mobile devices.

Key Features

  • Short/Mid-range detection: 10 m

  • Per-pixel zoon-histogramming TDC

Time-of-Flight (TOF) CMOS Image Sensor

SolidView’s two TOF CMOS image sensors (Legolas I & Legolas II) offer low-power TOF measurements with high precision for sub-5m detection range even in outdoor applications with strong sunlight.

Our sensor exhibits essential features, including
sunlight suppression, motion artifact suppression, and fixed-depth-noise reduction in a single chip. Therefore, SolidView’s sensor can be successfully applicable to the mobile and wearable devices with strong sunlight immunity and low energy consumption.

Key Features

  • Short-range detection: 5 m

  • On-chip sunlight suppression (Legolas-I)

  • Motion artifact suppression (Legolas-I)

  • Low power consumption under 70 mW (Legolas-II)

  • Fixed-depth-noise reduction (Legolas-II)
