Laser Distance Reader (CLDR)

Laser Distance Sensor module
Laser Distance Sensor concept

This CLDR is composed of a vertical board with a CMOS Sensor Inc. proprietary sensor array and a MCU, a lens module, a laser module, a DC brushless motor, all assembled in a compact plastic housing.


The ambient light cancellation is implemented, thus the CLDR is excellent for environments with/without lighting and indoor/outdoor conditions.


The CLDR is based on LiDAR technology with triangulation algorithm. Through the 360° laser scanning of a 2-D plane, a spatially precise plane bitmap is generated for SLAM (Simultaneously Localization And Mapping) purposes, which is very suitable for robot positioning and navigation.


With its own proprietary sensors and COB (Chip-on-Board) facility, CMOS Sensor Inc. is offering OEM/ODM support for customers’ requirements and applications.
