Abstract
A laser therapy method and apparatus is disclosed. The optical coherence property of the therapy laser is actively controlled to provide optimum therapy results for difference types of biological tissue and body parts.
Claims27
A method for using an optimized laser therapy device for a subject biological tissue, the method comprising the steps of:
- providing a laser element to produce a laser beam;
- causing the laser beam to enter the biological tissue and produce an interference induced speckle pattern of intensity;
- and
- controlling a coherence length of the laser beam to control the dimensions of the speckle pattern so as to achieve an optimized laser therapy result.
1 more element
A method for using an optimized laser therapy device for a subject biological tissue, the method comprising the steps of:
- providing a laser element to produce at least two laser beams;
- causing the laser beams to enter the biological tissue and produce an interference pattern of intensity;
- and
- controlling a coherence length of the laser beams and an angle between the laser beams to control the dimensions of the interference pattern as to achieve an optimized laser therapy result.
1 more element
An optimized laser therapy device for a subject biological tissue comprising:
- means for producing at least one laser beam;
- means for causing the at least one laser beam to enter the biological tissue and produce an interference pattern of intensity;
- and
- means for controlling a coherence length of the at least one laser beam to control the dimensions of the interference pattern as to achieve an optimized laser therapy result.
