Summary of the Inventive Concept

A retinal camera system that dynamically adjusts the optical stop to optimize image quality based on real-time eye movement tracking data, enabling high-quality retinal imaging despite eye movement during the imaging process.

Background and Problem Solved

The original patent for retinal cameras having movable optical stops addresses the need for high-quality retinal imaging. However, it does not fully account for the inherent limitations of eye movement during the imaging process, which can lead to image distortion and decreased image quality. This inventive concept builds upon the original patent by introducing real-time optical stop repositioning, thereby minimizing image distortion and ensuring high-quality retinal imaging.

Detailed Description of the Inventive Concept

The enhanced retinal camera system comprises an optical stop repositioning mechanism that dynamically adjusts the optical stop in response to real-time eye movement tracking data. This is achieved through the integration of an eye tracker and a controller that determines the amount of movement caused by the spatial adjustment of the eye during the imaging process. The controller then repositions the optical stop to a specified location, ensuring optimal image quality. The system can be further enhanced with a servomotor-driven optical stop repositioning mechanism, enabling high-speed optical stop adjustments during the imaging process.

Novelty and Inventive Step

The new inventive concept introduces the novel feature of real-time optical stop repositioning based on eye movement tracking data, which is not present in the original patent. This feature enables the system to dynamically adjust to eye movement during the imaging process, thereby minimizing image distortion and ensuring high-quality retinal imaging.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of actuators, such as pneumatic or piezoelectric actuators, to drive the optical stop repositioning mechanism. Additionally, the system could be integrated with other retinal imaging technologies, such as optical coherence tomography (OCT), to provide a more comprehensive retinal imaging solution.

Potential Commercial Applications and Market

The enhanced retinal camera system has significant commercial potential in the medical imaging industry, particularly in the fields of ophthalmology and optometry. The system's ability to provide high-quality retinal imaging despite eye movement during the imaging process makes it an attractive solution for clinicians and researchers seeking to diagnose and monitor retinal diseases.
