INTEGRATED OPTICAL DEVICE FOR LUMINESCENCE SENSING

摘要

An integrated luminescence sensor (200) includes a light pipe (208) in optical communication with a luminescence sensing layer (220) . A source of excitation illumination (204) is coupled to the light pipe (208) and disposed to direct excitation illumination toward the sensing layer (220) . A luminescent light detector (202) is also coupled to the light pipe (208) and is disposed to detect luminescent illumination luminescing from the sensing layer (220) , which luminescence is related to interaction between the sensing layer (220) and a substance of interest (222) .
