Light Field-Modulable Optical Needle Assembly

摘要

This invention relates to a light field-modulable optical needle assembly including a coherent light source, a light conduction member and a light modulation member. The light conduction member includes a light incident face that is proximate to the coherent light source, a light exiting face that is opposite to the light incident face and distal from the coherent light source, and a surrounding face that peripherally extends from the light incident face to the light exiting face to be connected therebetween. The light modulation member is disposed proximate to one of the light incident face, the light exiting face and the surrounding face of the light conduction member and is formed with a microstructure. The light emitted from the light field-modulable optical needle assembly has a light output power distribution adjustable by the microstructure of the light modulation member.

主权项

1. A light field-modulable optical needle assembly adapted for conducting a phototherapy, comprising
a coherent light source; a light conduction member that has a light incident face which is proximate to said coherent light source, a light exiting face which is opposite to said light incident face and distal from said coherent light source, and a surrounding face which peripherally extends from said light incident face to said light exiting face to be connected therebetween; and a light modulation member that is disposed proximate to one of said light incident face, said light exiting face and said surrounding face of said light conduction member, said light modulation member being formed with a microstructure, wherein when light is emitted from said coherent light source, the emitted light enters and exits said light conduction member and said light modulation member so as to have a light output power distribution adjusted by said microstructure of said light modulation member.
