N2 - An integrated probe has been developed containing the essential optoelectronic components necessary for monitoring tissue perfusion using the laser Doppler principle. The device includes a VCSEL for illumination, and a chip containing photodetectors, analog amplifiers for signal enhancement, and digital circuitry for external probe control. VCSEL and detector chip are mounted on a common ceramic platform, which also includes an integrated temperature sensor. A Peltier element may be included for temperature stabilization, or thermal cycling for physiological purposes. Two special chips have been developed: one containing an array of five detectors, at various distances from the laser, which will allow for some degree of depth discrimination, and a single detector chip. In this paper the multidetector chip and the probe design are presented.
