Claim 0:
1. A system for obtaining a multispectral image of a scene, the system comprising:
a nominal light source configured to emit a nominal flux onto the scene;
a first light source configured to emit first light onto the scene during a first sensing period;
a second light source configured to emit second light onto the scene during a second sensing period;
an imaging device including a monochromatic imaging sensor and a controller connected to the monochromatic imaging sensor,
the monochromatic imaging sensor configured to:
sense the first light that is reflected off of the scene during the first sensing period; and
sense the second light that is reflected off of the scene during the second sensing period; and

the controller configured to:
receive signals from the monochromatic imaging sensor as imaging data, the signals corresponding to the first and the second light sensed during the first and the second sensing periods, respectively;
store the imaging data; and
analyze pattern data of the imaging data;

wherein the nominal light source is off during the first sensing period and the second sensing period; and wherein the multispectral image of the scene is generated using the imaging data.
