What is Distance Imaging Camera Sensor Technology?

Distance imaging camera sensor technology is a fascinating advancement in the field of imaging and measurement.
These sensors are capable of capturing images with depth information, essentially allowing the camera to understand the distance between objects in its field of view.
This technology typically combines traditional 2D imaging sensors with depth-sensing capabilities, which are often achieved through methods like time-of-flight, structured light, or stereo vision.

Understanding how these sensors work can give us insights into their diverse applications and how they can be utilized effectively in various fields.

How Do Distance Imaging Sensors Work?

To comprehend the operation of distance imaging sensors, it’s important to explore the foundational methods they employ to capture depth information:

**Time-of-Flight (ToF)**: This method measures the time it takes for a light signal to travel to an object and back.
By calculating this time, the sensor can determine the distance to the object.

**Structured Light**: This technique projects a pattern of light onto an object.
The deformations in the pattern are then analyzed to calculate the depth and shape of the object.

**Stereo Vision**: Mimicking human binocular vision, stereo cameras use two or more lenses to capture images from slightly different perspectives.
By comparing these images, the system can calculate the distance to objects.
