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.
A Comprehensive Look at Sensors
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.
Position correction using images
Measuring the specified point's
height and height differences
- A: High precision CMOS sensor
- B: High-intensity LED illumination
- C: High luminance laser
- 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.
