Which of the following is not a sensor mode taught in class?

Explanation:
The main idea here is distinguishing imaging modalities from active ranging techniques. The class covers passive imaging modes across different parts of the spectrum: electro-optical imaging in the visible range, infrared imaging, and SWIR imaging. These capture 2D images using ambient or reflected light without emitting their own light source. LIDAR, however, is an active sensing method: it emits laser light, measures the time it takes to return, and constructs distance information to create 3D point clouds. It isn’t a standard imaging sensor mode like the others, which is why it isn’t considered a sensor mode taught in this context.
