Othalmoscopes TRIZ Cases
- Optical Fiber Light Collector for Fundus Spectroreflectometry
Integrating extraction fibers within a light collector reduces device complexity while maintaining spectral analysis precision.
- Asymmetric Fundus Imaging Optical System for Ghost Flare Reduction
Offsetting illumination and imaging axes in a fundus camera prevents overlapping optical paths, eliminating ghost flares while maintaining wide-angle coverage.
- Scanning Laser Ophthalmoscope Aberration Correction
Static aberration correction element modifies light beam phase to correct scan relay aberrations, reducing peripheral blurring and dimming.
- Fundus Image Tracking via Pattern Matching for Eye Motion
An ophthalmologic apparatus extracts a template image from a first fundus image and evaluates subsequent images using pattern matching to determine if they are affected by eye motion.
- Ophthalmologic Apparatus Small Pupil Imaging
An ophthalmologic apparatus merges OCT and retinal camera optical paths to acquire fundus images.
- Fundus Camera Multi-Wavelength Retinal Layer Imaging
Multi-wavelength illumination targets distinct retinal depths, resolving the trade-off between single-layer imaging capability and system complexity.
- Diffraction Grating Wavelength Selection for SLO
A diffraction grating separates broadband light into angularly distinct wavelengths, replacing expensive tunable lasers in scanning laser ophthalmoscopy.
- Retinal Imaging Sensor Integrating Multiple Scans for Signal-to-Noise Ratio
An eye examination sensor integrates reflected light across multiple optical scans to accumulate signal energy and produce a single retinal image.
- Ophthalmological Apparatus Pseudo Alignment Index for Eye Positioning
Control processor displays a pseudo alignment index image based on three-dimensional eye position data.
- Ocular Fundus Inspection Apparatus with Infrared Focusing
A beam splitter directs visible light and near-infrared radiation through a dichroic mirror to stabilize eye alignment.
- Ophthalmic Device Turning Drive Unit for Face Contact Avoidance
A turning drive unit rotates and translates an ophthalmic optical head horizontally.
- Movable Mirror Optical Path Coupling Fundus Inspection
A movable mirror replaces complex dichroic beam splitters to reduce interference signals and simplify manufacturing in fundus inspection systems.
- Galilean Tele-microscope Attachment for Binocular Indirect Ophthalmoscope
A Galilean tele-microscope attachment magnifies the fundus image produced by a hand-held condensing lens.
- Ophthalmic OCT Scan Pattern Positioning
Adjustable scan pattern images enable flexible positioning of intersection areas within the scannable region.
