Title: Contactlessly registering internal pressure of eye - illuminating eye by modulated IR radiation to use photo-acoustic effects
Inventor: SPAHN JUERGEN
IPC: A61B3/16
Filed: 1989-06-07
Abstract: The reaction of the eye to illumination by the modulated i.r. beam is converted to a measurement signal varying with time by a detector. This signal is electronically processed. The i.r. beam has a narrowly limited wavelength range. Pref., a laser light is used. The reaction of the eye is measured by using the thermal radiation or thermically-induced changes in refractive index.  The measuring signal can be processed by a transcient recorder or boxcar averages. A curve analysis of the modulation frequency spectrum is made for evaluation. ADVANTAGE - Low cost, high power, small construction achieved by use of C02 waveguide laser.
