Solution

LiDAR application solution for assistive focus

Provide target distance to cameras, projectors, or thermal devices so the controller can narrow the focus range.

Camera system using compact LiDAR for assistive focus distance

Scenario

Application scenario

Assistive focus uses LiDAR to add target distance, while final focus quality still depends on optics, imaging algorithms, the target region, and device calibration. LiDAR does not replace the complete autofocus system.

Engineering problem

Low light or low-texture targets can reduce image-only ranging stability.
The LiDAR measurement zone and image focus region require spatial calibration.
Transparent, reflective, small, or multiple targets need an explicit selection rule.

Why LiDAR

Direct range can narrow lens search or select a focus preset and then work with image feedback in a closed loop.

Workflow

Define the focus target region, working range, and response requirement.
Calibrate the LiDAR measurement zone against the camera or projector optical path.
Map distance and status to lens position, focus band, or search start point.
Validate low light, multiple targets, transparent surfaces, and reflections.

Technology comparison and selection

Dimension	Condition	LiDAR	Alternative	Alternative performance	Conclusion
Distance input in low light	The imaging system needs a faster initial focus range.	Provides direct distance independent of image texture.	Image-only autofocus	Uses image feedback directly but may search longer on low-light or low-texture targets.	Use LiDAR to narrow the search; optics and image feedback still confirm final sharpness.

Product selection guide

Current material supports 2 candidates. Review product facts, rationale and boundaries together.

Model	Key product facts	Best fit and rationale	Operating boundary	Product details
TF-NOVA	Output data One-dimensional Area Detection Solution Measuring range 14 m Interface UART, I/O, I²C Protection IP65	For focus systems that need wider horizontal distance input than one point; the 14°×1° line pattern can provide an area-ranging cue to lens control.	Spot coverage is not an image or a focus result; align the optical axes and validate target size, background and control algorithm with the lens system.	View product
TF-Luna	Output data Single-point Distance Value Measuring range 0.2 ~ 8 m Interface UART, I/O, I²C Protection Without enclosure	For focus assistance needing one controlled distance direction with low power and compact mounting.	Align the single range point with the lens axis and target area; the sensor does not drive the lens directly or guarantee final focus quality.	View product

Installation and integration

Align the LiDAR measurement zone with the real focus target, record optical-axis offsets, and integrate distance and data status into the lens or device controller.

FAQ

Frequently asked questions

Is image autofocus still needed after adding LiDAR?

Usually yes. LiDAR narrows the search with target distance, while lens calibration and image feedback still confirm final focus and sharpness.
