Sony patents medical camera that splits light for clearer views
Sony describes an imaging device that uses a prism to split light from a patient into visible and special wavelengths. This allows two separate sensors to capture distinct images, with the prism designed to let over 90% of the special light reach its dedicated sensor.
In the filing’s own words
An imaging device includes: a prism configured to separate visible light and special light from each other, the visible light and the special light included in light from an observation target; a visible light imaging sensor configured to image the visible light separated by the prism; and a special light imaging sensor configured to image the special light separated by the prism. A ratio of spectral transmittance of the visible light toward the special light imaging sensor to spectral transmittance of the visible light toward the visible light imaging sensor in the prism is 0.25 or more and 4 or less, and spectral transmittance of the special light toward the special light imaging sensor in the prism is greater than 90%.
What exactly they claim (claim 1)
1. An imaging device comprising: a prism configured to separate visible light and special light from each other, the visible light and the special light included in light from an observation target; a visible light imaging sensor configured to image the visible light separated by the prism; and a special light imaging sensor configured to image the special light separated by the prism, wherein a ratio of spectral transmittance of the visible light toward the special light imaging sensor to spectral transmittance of the visible light toward the visible light imaging sensor in the prism is 0.25 or more and 4 or less, and spectral transmittance of the special light toward the special light imaging sensor in the prism is greater than 90%.
