Compact Fluorosensor Based on a Continuous-Wave Violet Diode Laser, in Integrated Spectrometer and Fiber-Optic Sampling

A compact fluorosensor with a fiber-optic measurement probe was developed, employing a continuous-wave violet diode laser as an exciting source and an integrated digital spectrometer for the monitoring of fluorescence signatures. Results from measurements on vegetation and human premalignant skin lesions are reported, illustrating the potential of the instrument.
