A flexible eyecup has a proximal opening end attached to the housing and surrounding the eyepiece lens and a distal opening end shaped to press against a face around an eye. An image sensor is adapted to acquire a retinal image of the eye through the eyepiece lens when the flexible eyecup is pressed against the face. A field source generates a field. A field sensing system senses the field. One of the field source or the field sensing system is disposed in or on the flexible eyecup and the other one is rigidly mounted to the housing. A controller is coupled to the field sensing system for tracking a relative position of the eyepiece lens relative to the field source to aid aligning the eyepiece lens to the eye."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Alignment detection of ophthalmic camera system","description":"An ophthalmic camera system includes an eyepiece lens disposed in or on a housing.
