title: Experimental verification of compressive reflectance field acquisition.
abstract: We demonstrate compressive sensing (CS) of the eight-dimensional reflectance field (RF), which describes spatial and angular information of light rays toward and from an object. The RF is also known as the bidirectional scattering surface reflectance distribution function. In this method, incident rays and reflected rays to/from the object are modulated by variable coding masks, and the modulated rays are multiplexed onto an image sensor. The images captured with multiple mask patterns are decoded by a CS algorithm. The RF of the object was successfully reconstructed from less than half of the number of measurements required with conventional methods.
