Features

The NSI1000 features a state-of-the-art global shutter array architecture, allowing extremely high

sensitivity, while keeping low power dissipation.

Sensor Array Features

Applications

eTOF? LiDAR

Newsight’s eTOF? (enhanced Time-of-Flight) is a patented solution for 3D distance

measurement that allows unparalleled performance with less than a 1% error rate for

distances up to 100m, both in indoor and outdoor scenarios. The eTOF? solid-state LiDAR,

based on the NSI1000, is a complete solution for a versatile and affordable 3D mapping

device of 1024x32 points. Newsight offers a reference design which is highly configurable

for different applications and very flexible in coping with different scenarios and

environmental conditions.

The eTOF? LiDAR is designed for a wide horizontal field of view (FOV) and a high frame rate.

It provides high accuracy and precision with a high dynamic range.

The returned pulse can be sampled in 2, 3 or 4 windows. The diagram below illustrates one

method of eTOF implementation using 3 sampling windows. Distance is calculated by the

ratio of window A and window B, or window B and window C. Each frame accumulates

charge from many sub-frames as many as 100K times, based on the accumulated exposure

needed, to achieve optimal signal per distance and reflectivity.
