Infrared Laser and Sensing

LiDAR (Light Detection and Ranging) is a technology that uses invisible infrared laser light to measure the distance to a target.It emits laser light and calculates distance from the time difference (Time of Flight) until the reflected light returns, and by scanning the laser in a fixed direction, acquires the surrounding space as distance data on a two-dimensional plane (2D scan data). It can be installed and used in either horizontal or vertical orientations, enabling spatial scanning suited to the application. Compared with millimeter-wave radar, which uses radio waves, LiDAR uses shorter wavelengths and features the high resolution unique to light, allowing it to capture fine details of an object’s shape with high precision.

Value of LiDAR

LiDAR is a sensing technology that leverages the high speed and straight-line propagation of light to measure spaces precisely.
High Spatial Resolution
Detects subtle changes in distance, enabling the presence of small objects to be identified
Non-Contact 2D Detection
Acquires the distance to and positional relationships of targets on a two-dimensional plane with high accuracy
Privacy-Conscious Detection
Detects the movement of people and objects using distance data without capturing images
Because it is relatively unaffected by ambient brightness, LiDAR provides stable measurement even in darkness or backlighting, and its use is expanding across a wide range of indoor and outdoor applications.

Optex’s Unique Strengths and Applications

Intrusion Detection for Critical Facilities (REDSCAN Series)

Highly accurate detection of targets approaching or intruding on walls and fences at critical facilities such as airports, power plants, and data centers.Equipped with identification logic that detects only people while filtering out swaying vegetation and small animals based on the size, distance, and speed of the target.The Pro/mini-Pro series features built-in cameras that record video of intruders at the same time as intrusion detection, supporting post-event verification and incident analysis.It delivers high reliability at high-security facilities around the world.

    The Key to LiDAR Is Overcoming Environmental Challenges

    LiDAR’s high resolution is a major advantage, but because LiDAR uses light, it is affected by environmental changes such as rain, fog, and snow.Through rigorous evaluation testing, including heavy snow, dense fog, and prolonged rain tests, Optex has developed proprietary algorithms that minimize interference noise to the greatest extent possible.Even if a product offers advanced functions and high performance, it cannot deliver its full potential at the installation site if installation and settings are difficult.Another highly distinctive feature is Optex’s human-centered design philosophy of automating difficult settings so that anyone can use the product, as exemplified by the Automatic Area Correction function incorporated in REDSCAN Lite.
