An example hologram device may include a target holographic view of an encoded holographic image representing an alignment target; and a plurality of non-target holographic views of the encoded holographic image, each non-target holographic view indicating a position relative to the target holographic view.

A multi-spectral scan camera and methods are presented. Light beams are emitted from a plurality of light sources comprising a plurality of spectral wavelengths respectively. The light beams from the light sources are scanned across a field of view at a plurality of respective angles using a scan mirror, and each of the spectral wavelengths are received at respective detectors.
