Othalmoscopes TRIZ Cases
- Retinal Nerve Fiber Layer Diagnostic Parameter
A diagnostic parameter normalizes retinal nerve fiber layer thickness against distance from the optic disc center.
- Ophthalmic Imaging Apertures for Motion Artifact Reduction
Independent aperture movement resolves motion artifacts while maintaining high-resolution image quality in ophthalmic diagnostics.
- Slit-lamp Microscope Light Leakage Prevention via Controller
A slit-lamp microscope controller turns off the light source when slit blades close.
- Ophthalmic Tomographic Image Distortion Correction
An ophthalmic device corrects tomographic image distortion using intraocular distance measurements from interference light detection.
- Real-Time Ophthalmic Image Montage via Adaptive Optics Stabilization
Automated image acquisition and stitching algorithms reduce patient exposure to optical power while maintaining high resolution across the combined field.
- Retinal Imaging via Eye Tracking and Single-Point Sensing
A single-point sensing module measures retinal light reflections while an eye-tracking unit determines gaze position to construct detailed images.
- Perimeter Stimulus Presentation for Visual Field Inspection
A perimeter system presents visual stimuli to designated inspection and spaced regions.
- Interferometer Clock Generator for High-Speed OCT Sampling
Optical path length difference generates n-times frequency clock signals, resolving high-speed sampling complexity in swept-source tomography.
- Ophthalmoscope Axial LED Lighting Compact Design
Axial LED lighting and collimating lenses align the optical axis, eliminating transverse components that increase structural complexity.
- Slit Lamp Background Illuminator for Eye Exam Glaring
Background illuminator emits infrared and visible light beams to improve image contrast, reducing eye glaring during slit lamp eye examinations.
- Ophthalmic Imaging Apparatus Dynamic Autofocus Control
An ophthalmic imaging apparatus uses dual control units to deactivate and reactivate autofocus functions during fundus observation.
- Ophthalmic Scanning Pivot Point Control for Wide-Field OCT
Dynamic motion and feedback control maintain the scanning pivot point at the pupil center, expanding the field-of-view without increasing device cost.
- Blood Flow Measurement Apparatus Vignetting Optimization
Controller applies preliminary vignetting judgment to determine optimal optical shift, reducing measurement time and subject burden.
- Ophthalmic Eye Alignment Apparatus Using Visual Feedback
Processor generates graphical objects representing ideal and actual eye positions, reducing operator errors during ophthalmic instrument setup.
- Ophthalmologic Microscope Orientation via Purkinje Reflections
A control unit determines orientation parameters by processing specular reflection positions recorded in microscope images.
- Slit Lamp Microscope Fluorescence Imaging Goblet Cells
A slit lamp microscope captures fluorescent goblet cells using 405 nm excitation and optical filtering.
- Auto-Focusing Image Capture for Fundus Examination
An image capturing apparatus uses a dual-lens module to detect light point images for precise cornea and fundus focusing.
- Ophthalmic Device Alignment Mechanism for Flare Suppression
A second alignment unit determines optical axis position based on perpendicular deviation to maintain constant path length.
- Ophthalmic Camera Automatic Focus via Luminance Analysis
A focusing optical element moves along an optical axis to capture retinal images using a photodetector signal.
