Abstract
We report preliminary results on the use of a far
infrared emitting quantum cascade laser for active
illumination in foggy conditions. The applications would
be e.g. in cooperative driving and improvement of
visibility for car drivers in adverse road weather
conditions. It has long been known that the infrared
wavelengths in the thermal band of 9 - 13?m allow better
visibility in foggy conditions, compared to near infrared
or visible bands. Therefore already thermal cameras have
been installed in cars, with dashboard displays, in order
to improve safe driving. However, these units are only
utilising the emittance of the targets themselves,
without the possibility of active illumination. This is
because until recent years, no practical solid state
laser illuminators have been available for the purpose.
Recent increase of availability and powers of quantum
cascade or distributed feedback lasers has changed the
situation. We show some preliminary results on the use of
a high peak power, pulsed quantum cascade diode laser in
an experimental fog chamber for active illumination,
viewed with a compound semiconductor, direct bandgap
infrared camera.
