Drag the object. The chromatic lens focuses different colors at different depths. The sensor detects which color is "in focus" to calculate distance.

lightbulb Principle

White light passes through a hyper-chromatic lens. Blue light focuses closer, Red light focuses farther. The reflected light is analyzed by a spectrometer. The peak wavelength directly indicates the surface position.
