Basler blaze Time-of-Flight Camera – Frequently Asked Questions (FAQ)

On this page you’ll find answers to some of the most common technical questions concerning the Basler blaze Camera.

1. What is Time of Flight?

Time of Flight is a method for distance measurement. The time it takes for light to travel from the light source to the object then return to the sensor is measured and calculated into a distance.

2. How accurate is the measurement of the Basler blaze camera?

The Basler blaze camera is accurate to a few millimeters, depending on the scene. The user’s manual contains a graphic with detailed accuracy measurement data.

3. What resolution does the Basler blaze camera offer?

The Basler blaze camera offers a resolution of 640 pixels (horizontal) x 480 pixels (vertical).

4. Which sensor is used in the Basler blaze camera?

The Basler blaze camera uses the latest ToF specific Sony DepthSense™ IMX556PLR sensor.

5. Which applications are suitable for the Basler blaze camera?

The Basler blaze camera is used in a variety of applications in the fields of logistics, factory automation, robotics and medicine.

6. What is the framerate for the Basler blaze camera?

The Basler blaze camera runs at up to 30 fps in free run.

7. How does the operating temperature affect the accuracy of the Basler balze camera?

The camera is factory-calibrated in an ambient temperature of 22°C, and that is where it performs most accurate. The measurement values deviate by less than a millimeter per °C. After a cold start, the camera requires some minutes to achieve thermal stability. You will find more detailed measurement data in the blaze User Manual.

8. Can I buy the Basler blaze camera with another lens?

No, the current Basler blaze camera is only sold with a fixed aperture angle. Further models are in planning. Please get in contact with your sales rep.

9. Is the Basler blaze camera pre-calibrated to ensure maximum accuracy?

Yes, each individual camera is pre-calibrated to each peak performance.

10. What kind of light source is used in the Basler blaze camera?

The latest Basler blaze camera uses four VCSEL laser diodes as its light source.

11. What is the wavelength spectrum for the Basler blaze camera?

The Basler blaze camera works with a wavelength spectrum of 940nm. The light is invisible for humans.

12. What is the modulation frequency of the Basler blaze camera?

The camera operates at different frequencies. 100 Mhz is the highest.

13. Can I use the Basler blaze camera for outdoor applications as well?

Yes, the camera works under sunlight conditions. Please check the user manual for details.

14. What is the protection class rating for the Basler blaze camera?

The latest model blaze-101 is rated to protection class IP67.

15. I'd like to use the camera in an outdoor setting and want to put it into a housing. What factors require special consideration? Or can I simply put the blaze camera into a standard protection housing?

Cooling is a primary consideration before mounting into a protective housing, as is avoidance of stray light (no reflecting housing parts near the lens).

The protective glass must not cause reflections. Ideally the lens and the LEDs will have separate protective glasses.

16. I'd like to use multiple Basler blaze cameras in my application.

There is a dedicated operation mode to minimize camera interference. Alternatively, you trigger the cameras one after another or you use the PTP synchronization feature.

17. Can I use a 2D and a 3D Basler blaze camera within one system?

Yes, you can install the blaze driver and the pylon SDK on one computer.

18. How can I configure and modify image formats for amplitude, intensity and range map?

Each time it captures an image, the camera delivers a multipart image that contains multiple images, such as a point cloud and an intensity profile. The parameters Image Component Selector, Component Enable and Pixel Format allow you to define which images are in a container.

19. I have to download a GenTL Producer compliant with the GenICam standard to operate the Basler blaze camera. What exactly is that standard and why does Basler use this process?

GenTL is the third module of GenICam. While GenApi and SFNC are more oriented toward the camera's settings, GenTL regulates the transport of the image data. GenTL is the latest module.
