A second type of patternators are based on using planar liquid laser induced fluorescence.
2.
The potential technologies evaluated were Long-Wave Infrared ( LWIR ), Differential Scattering ( DISC ), and Ultraviolet Laser Induced Fluorescence ( UV-LIF ).
3.
The geomicrobiological aspects of this expedition had three objectives : " to test laser induced fluorescence emission ( L . I . F . E . ) to be used for the exploration of the Mars regolith and poles; monitor global climate change; and to evaluate methods for detecting hydrocarbon contamination and subsequent bio-remediation in a fragile, endangered ecosystem . " The results indicate that Lake Untersee, as a permanently ice-covered region, has very little usable soil and could be likened to the polar regions of Mars.
