| titleOfInvention | Fluorescein angiography testing system based on 785 nm wavelength light source |
| abstract | A fluorescein angiography testing system based on a 785 nm wavelength light source relating to the technical field near infrared fluorescence imaging, and comprising a near infrared laser light source (100), a visible light illumination light source (200), a light collector (300), a light splitter (400), a visible light filter (500), a near infrared light filter (600), a color camera (700), a near infrared camera (800), a terminal display (900), and a housing (1) used for contact with a tissue (2) of a patient. Light source supports (11) are arranged inside the housing (1), and the near infrared laser light source (100) and the visible light illumination light source (200) are arranged on the light source supports (11). An observation channel (12) is arranged inside the housing (1) and connected to the light collector (300), the light splitter (400) is connected to the light collector (300), the color camera (700) is connected to the light splitter (400) by means of the visible light filter (500), and the near infrared camera (800) is connected to the light splitter (400) by means of the near infrared light filter (600). The fluorescein angiography testing system can block unwanted laser light reflected by the surface of a tissue (2) back to the fluorescein testing device, avoiding the impact of a large amount of reflected laser light on the image, improving the signal-to-noise ratio in the image, and improving the effect of the image. |
