Laser Telemeter Axis Compensation in Stabilized Binoculars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld binoculars with image stabilization systems face challenges in accurately aiming a laser telemeter due to stabilization interference with deliberate operator movements, making it difficult to maintain the laser axis on a target for a long enough time to perform telemetry firing.
Innovation Solution
A method that calculates the shift between the real and stabilized images, positions the stabilized image on a predetermined screen position, and automatically triggers the laser shot when the distance between the firing window and the target is below a certain threshold, using a processing unit to compensate for stabilization delays and operator movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If image stabilization is activated to compensate for operator movements, then image stability is improved, but the laser axis shifts relative to the stabilized image making accurate aiming difficult
Solution Approach 1:
The system continuously monitors the position of the laser reticle relative to the stabilized image and automatically adjusts the laser axis position to compensate for stabilization-induced shifts. This closed-loop feedback mechanism ensures that the laser beam remains accurately aligned with the target despite image stabilization movements.
Solution Approach 2:
A processing unit acts as an intermediary between the image stabilization system and the laser telemeter, calculating the shift between the real image and stabilized image, and determining the appropriate compensation for the laser axis position based on these calculations.
2Measurement precision
If stabilization is suppressed during telemetry phase to maintain laser accuracy, then laser aiming precision is improved, but image stability is lost
Solution Approach 1:
The system dynamically adjusts the stabilization system's behavior based on the operational phase. During the telemetry phase, the stabilization continues to operate but the laser axis is dynamically compensated for its position shifts, allowing both image stability and laser precision to coexist through adaptive control.
3Measurement precision
If mechanical stabilization devices are used to stabilize both imaging and laser axes, then laser aiming precision is improved, but device portability deteriorates
Solution Approach 1:
The patent replaces complex mechanical stabilization devices with a digital/image-based stabilization approach combined with computational laser axis compensation. The processing unit calculates the shift between real and stabilized images and uses this information to adjust the laser axis position, eliminating the need for bulky mechanical stabilization hardware while maintaining both image and laser precision.
