Application Overview

Infrared thermal imagers can‘t detect iris because of their small depth of field and limited focusing
accuracy. Benewake LiDAR is installed on the side of the camera, the distance between the device and
the iris of human body can be accurately measured to assist in focusing. Generally, LiDAR assists the
camera to focus accurately within the range of 1-2m. Over 4-5m range, camera will not focus on the eye
of human.

LiDAR is a non-contact, based on Time of Flight principle measurement equipment. Single beam of light
can be used for eye to camera detection. It is totally no harm to human eyes. LiDAR is becoming a autofocus
sensor for camera and any other devices.
