Orbbec Femto Bolt Time-of-Flight 3D Camera

Orbbec Femto Bolt is a compact indirect Time-of-Flight 3D camera jointly developed by Orbbec and Microsoft. It combines a 1-megapixel ToF depth sensor, 4K RGB imaging with HDR, a 6 DoF IMU, and precise multi-camera synchronization in a USB Type-C RGB-D camera.

Femto Bolt supports depth resolution up to 1024 × 1024, a mode-dependent operating range extending from 0.25 m to 5.46 m, and an ultra-wide 120° × 120° depth field of view. Its Azure Kinect-compatible depth modes and Orbbec K4A Wrapper provide a practical migration path for applications previously developed around the Microsoft Azure Kinect DK.

1 MP Time-of-Flight Depth
— Supports wide-field depth resolution up to 1024 × 1024 with operating ranges extending to 5.46 m depending on the selected depth mode.

120° Ultra-Wide Depth FOV
— WFOV modes provide a 120° × 120° field of view for broad scene coverage and full-body capture.

4K RGB with HDR
— Captures RGB video up to 3840 × 2160 at 30 fps for detailed RGB-D imaging and visualization.

Azure Kinect Migration
— Uses the same depth operating modes and performance as Azure Kinect DK, with an Orbbec K4A Wrapper for compatible applications.

Integrated 6 DoF IMU
— Integrated accelerometer and gyroscope provide synchronized motion and orientation data.

Multi-Camera Synchronization
— An 8-pin synchronization interface provides accurate trigger control for multi-camera and multi-sensor installations.
