Abstract
Disclosed herein is an apparatus suitable for light scanning. The apparatus comprises a light source and a photonic crystal. The light source is configured to direct a light beam along an optical axis toward the photonic crystal. The photonic crystal is configured to direct the light beam along a direction at an angle relative to the optical axis. The angle is a function of wavelength of the light beam. The apparatus may also comprise a partial toroid lens configured to diverge the light beam received from the photonic crystal. The light source of the apparatus may be configured to change the wavelength continuously across a range of wavelengths.
