LidarAC

LidarAC – RX is the handheld control and monitoring interface for the LidarAC system, built to extend Tilta Nucleus M and N setups for modern focus workflows.

The idea is simple: bring tools normally found on high-end hand units to the Nano by using an iPhone.

The system consists of two Modes.
RX acts as the handheld interface and connects to the Nucleus Nano II via Bluetooth.
TX runs on a second iPhone mounted on the camera (iPhone 12 Pro or newer) and provides LiDAR-based distance data.

RX already enhances the Nucleus on its own with custom lens profiles, focus scaling, and marker tools. The full potential unlocks when paired with TX, adding real-time distance data directly into the focus workflow.

Instead of relying on raw motor values, the system translates focus into usable distance context. Depth of field is calculated and visualized in real time, helping focus pullers make faster and more confident decisions, especially in dynamic scenes.

Lens profiles allow precise mapping between LiDAR data and lens behavior, including aperture-based depth of field. Camera profiles handle CoC and sensor offset, ensuring accurate results in real-world setups.

The focus scale is fully interactive and can switch between a flat mode and a focus wheel inspired mode. Values can either be mapped visually like on the lens for intuitive pulling, or displayed linearly to better understand spatial relationships within the scene.
Marker and tracking tools make it easy to set, follow, and recall focus points. Features like spot measurement, 2D and 3D tracking, and a top-down LiDAR view provide clear spatial awareness on set. Haptic feedback increases as you approach a marker, giving intuitive confirmation without looking away.

Key features:
• Real-time LiDAR distance data for people, faces, and eyes
• Spot distance measurement
• 2D and 3D tracking points
• Top-down LiDAR scene view
• Custom lens profiles with depth of field visualization
• Multiple focus scale modes (linear, lens matched, logarithmic)
• Marker-based focus assistance with haptic feedback
