摘要： A fluorescent activated light detector for detection of time modulated IR signals of preselected wavelength includes an IR light collecting member (12) made of a solid transparent core material (13) with a fluorescent light absorbing dye (15) molecularly dispersed throughout the core. Photodiodes (14) are operatively associated with the collecting member for detecting fluorescent light emitted by the collecting member upon exposure to incident IR radiation of the preselected wavelength. The light collecting member has a surface area A1 much greater than an active area A2 of the photosensing means. Use of this fluorescent activated light detector allows for increasing the effective transmission distance of infrared free space communication links without requiring an increase in transmitter radiated power.
