Abstract
An exemplary illumination source is provided. The illumination source includes a light integrating device for coupling to at least one optical structure at an output port. The light integrating device includes at least one input port. At least one light source produces at least one optical illumination coupled to the at least one input port. A light adjusting tool controls the optical illumination emitted by the light integrating device. The light adjusting tool controls uniformity of light emitted by the light integrating device by modifying at least one internal surface of the light integrating device.
Claims14
An illumination source comprising:
- a light integrating device for coupling to at least one optical structure at an output port, where the light integrating device includes at least one input port;
- at least one laser source coupled to at least one vibration source provides light input to the at least one input port, wherein
- the light integrating device homogenizes the light input from the at least one laser source to emit speckle-free uniform laser illumination at an output port of the light integrating device.
A method for producing illumination, the method comprising:
- providing a light integrating device for coupling to at least one optical structure at an output port, where the light integrating device includes at least one input port;
- producing, using at least one laser source coupled to at least one vibration source, light input to the at least one input port;
- and
- delivering, at an output port of the light integrating device, speckle-free and uniform laser illumination, wherein the light integrating device homogenizes the light input from the at least one laser source.
