Detection based on “Light”
What is a Camera with a Built-in Laser Sensor?

This section provides a detailed look at image-based laser sensors.

Outline

The laser displacement sensor built into the camera represents a new concept in laser sensors, in which the camera identifies the target object using an image, and by tracking a specified point the laser can measure the height of that point and any height differences in relation to it.

height and height differences

Principle

Principle
  1. A: High precision CMOS sensor
  2. B: High-intensity LED illumination
  3. C: High luminance laser
  4. D: High precision MEMS mirror

In the drive scan system, the image data and the height information are captured in a single CMOS. The camera captures a photograph of the target object, extracts the outline and corrects the positioning. The laser scans the specified area by means of a MEMS mirror which continuously changes the laser's irradiation angle, allowing for height information to be captured. The 2 sets of data are formed into an image and processed.
