Enhanced Retinal Cameras with Dynamic Optical Stop Adjustment

The inventive concept improves retinal imaging by dynamically adjusting the optical stop's position in response to changes in the eye's spatial orientation during imaging, resulting in higher-quality images and reduced motion artifacts.

The original patent's retinal cameras, while effective, have limitations in capturing high-quality images due to the eye's natural movements during imaging. This inventive concept addresses these limitations by introducing a movable optical stop that can dynamically adjust its position to compensate for the eye's spatial adjustments, ensuring optimal image capture.

The inventive concept comprises a retinal camera system with a movable optical stop, which is configured to dynamically adjust its position in response to changes in the eye's spatial orientation during imaging. The movable optical stop is actuated by a voice coil motor or a piezoelectric actuator, enabling fast and precise adjustments. The system also includes an eye tracker to monitor the eye's spatial orientation and a controller to dynamically adjust the movable optical stop's position based on the eye tracker's output. This results in higher-quality images and reduced motion artifacts.

The new claims introduce the concept of dynamic optical stop adjustment in response to changes in the eye's spatial orientation, which is not present in the original patent. This innovative approach enables the capture of higher-quality retinal images and reduces motion artifacts, providing a significant improvement over existing retinal cameras.

Alternative embodiments of the inventive concept could include using different types of actuators, such as servomotors or pneumatic actuators, or incorporating additional sensors to monitor the eye's movements. Variations could also include designing the movable optical stop to accommodate different pupil sizes and shapes, enabling more accurate and efficient retinal imaging for a wider range of patients.

The enhanced retinal camera system has significant commercial potential in the medical industry, particularly in ophthalmology and optometry. The improved image quality and reduced motion artifacts will enable healthcare professionals to make more accurate diagnoses and monitor retinal health more effectively, leading to better patient outcomes and improved healthcare services.
