LASER SPECKLE REDUCTION AND PHOTO-THERMAL SPECKLE SPECTROSCOPY

LASER SPECKLE REDUCTION AND PHOTO-THERMAL SPECKLE SPECTROSCOPY

A photo-thermal speckle spectroscopy device having an infrared laser, a visible laser, a foam, and a camera. The infrared and visible lasers are focused on the foam, which causes the visible laser to scatter. A camera records the speckle pattern, which shifts when the IR laser is turned on. The rela...

Zusammenfassung:A photo-thermal speckle spectroscopy device having an infrared laser, a visible laser, a foam, and a camera. The infrared and visible lasers are focused on the foam, which causes the visible laser to scatter. A camera records the speckle pattern, which shifts when the IR laser is turned on. The related method of photo-thermal speckle spectroscopy is also disclosed.
