Krypton filled flashlamp: a possible new light source for near infrared spectroscopy in vivo.
We have designed a reliable and flexible low cost instrument for NIR spectroscopy. A krypton filled flashlamp was used as inexpensive light source. Providing a number of suitable emission peaks in the NIR, this flashlamp is ideal for NIR spectroscopy. Application to other NIR spectroscopy systems, e.g. to CCD (Charge Coupled Device) spectrophotometers, should be possible. The introduced system was tested on human arm tissue during arterial occlusion. Results equivalent to those described by other authors could be obtained by this new technical approach.
