Abstract
An imaging system includes a visible light source configured to output visible light and a near infrared laser light source configured to output an excitation laser light. The system also includes a camera assembly having: a housing with an opening configured to receive a combined light, which includes visible light and infrared fluorescence light. The combined light entering the housing along a combined light path, the combined light may include visible light and infrared fluorescence light; an aperture mechanism having an adjustable opening disposed along the combined light path; a beamsplitter configured to split the combined light into the visible light along a visible light path and the infrared fluorescence light along an infrared light path; a visible light sensor configured to receive the visible light and to generate visible light image data; and an infrared sensor configured to receive the infrared fluorescence light and to generate infrared fluorescence image data.
