LUMIS2 Fluorescence Images

After a series of successful deployments both on SCUBA during the day and snorkeling during the day and night, LUMIS2 has captured some very compelling images of coral and algae fluorescence. Below is a set of frames from our most recent nighttime snorkeling ops. In the left column are the fluorescence frames taken with the blue strobes on LUMIS2 and the right column are the matching white strobe light frames of the same subject taken 50ms later. Each “frame” consists of four separate images arranged as follows:

(Green 510-530)  (Color no filter)

(Red 665-695)     (Orange 568-588)

Note that these images are “raw” uncorrected and that the Orange filter image has twice the gain of the Green and Red images.
