Abstract: Frequency-based mode mixing may be used to homogenize different modes in an optical fiber used for surgical illumination. A laser modulator may introduce frequency modulation to laser light to generate a homogeneous illumination field due to increased mode mixing in the optical fiber.

Abstract: Mechanical optics for mode mixing may be used to homogenize different modes in an optical fiber used for surgical illumination. A mechanical optical element, such as a rotating prism or a mirror membrane, may impart motion to an incident beam entering the optical fiber to generate a homogeneous illumination field from a coherent light source.

Abstract: Fiber-based mode mixing techniques may be used to homogenize different modes in an optical fiber used for surgical illumination. A vibrating fiber mechanism may impart mechanical motion to a portion of the optical fiber to generate a homogeneous illumination field from a coherent light source.

Abstract: The present disclosure provides a vitreous visualization system including a vitreous illuminator including a vitreous visualization light source and a vitreous visualization tool that transmits lights from the vitreous visualization light source into an eye having vitreous, a pupil, and a vitreous-pupil axis. The vitreous visualization system further includes a general illuminator, which may include a general light source and a general illumination tool that transmits light from the general light source into the eye. The present disclosure further provided a vitreous visualization system including only a vitreous illuminator that transmits light from the vitreous visualization light source into an eye having vitreous, a pupil, a vitreous-pupil axis, and a retina at an angle B with the vitreous-pupil axis of the eye such that the brightness of vitreous in the eye is higher than the brightness of the retina of the eye.

Abstract: Pixelated array optics for mode mixing may be used to homogenize different modes in an optical fiber used for surgical illumination. A pixelated phase array, such as a digital micromirror device or an LCD phase plate, may impart motion to an incident beam entering the optical fiber to generate a homogeneous illumination field from a coherent light source.
