Abstract

Multidimensional photography captures optical fields beyond conventional image sensors' capabilities. This paper proposes tunable multidimensional photography through active optical mapping, using a spatial light modulator (SLM) to dynamically map a high-dimensional light datacube onto a 2D sensor. This approach maximizes measurement flexibility and is demonstrated in hyperspectral and ultrafast imaging.
