optical fusion
Học thuậtThân thiện
Definition
Noun: - The combining of images from the two eyes to form a single visual percept: This is a neurological process where the brain merges the slightly different images received from each eye into one coherent, three-dimensional picture. It is a fundamental aspect of binocular vision.
Usage
- This term is primarily used in scientific, medical, and technical contexts related to vision, neuroscience, and psychology.
- It describes the or itself, not the resulting image.
- Example: "Depth perception relies on the brain's successful optical fusion of the two retinal images."
Examples
- Noun:
- The study examined how optical fusion develops in infants.
- A disorder in optical fusion can lead to double vision (diplopia).
- Virtual reality headsets must carefully manage the cues for optical fusion to create a believable 3D effect.
Advanced Usage
- "Sensory fusion": A broader term that can include optical fusion along with the integration of other sensory data.
- "Binocular fusion": A term often used interchangeably with optical fusion, emphasizing the role of both eyes.
- "Fusion threshold": The point at which the two images are successfully fused into one.
- The patient's fusion threshold was measured to assess their binocular vision.
Variants and Related Words
- Fusional vergence (n): The eye movements that help achieve and maintain optical fusion.
- Panum's fusional area (n): The small region in space where images from each eye can be fused into a single percept.
- Stereopsis (n): The perception of depth produced by optical fusion of two slightly different images.
Synonyms
- Binocular fusion: The merging of inputs from the two eyes.
- Sensory fusion: The integration of sensory information, which can include visual fusion.
Antonyms
- Diplopia: Double vision; the simultaneous perception of two images of a single object, indicating a failure of optical fusion.
- Suppression: The brain's ignoring of the input from one eye to avoid double vision, which prevents optical fusion.
Related Phrases
- "Achieve fusion": To successfully combine the two images.
- The visual therapy aims to help the patient achieve fusion.
- "Maintain fusion": To keep the single percept stable over time.
- Strong eye muscles are needed to maintain fusion while reading.
- "Fusion break": The point where the two images can no longer be held as one.
- The prism test determines the patient's fusion break point.
Noun
- the combining of images from the two eyes to form a single visual percept
