Optothermal measurement of haemoglobin and glucose in blood.

Prototype instruments are developed for determining haemoglobin and glucose content of blood based on optothermal spectroscopy. The optothermal instrument is described. The results of clinical haemoglobin and glucose tests show good agreement with standard methods.

Optothermal measurement of haemoglobin in blood.

A prototype instrument based on optothermal spectroscopy has been developed for determining the haemoglobin content of blood. The optothermal detector is described and consists essentially of a thin sapphire disc glued to a piezoelectric ring. The optothermal instrument is also described.
