Superresolved space-dependent sensing of temporal signals by space multiplexing

In this paper we present a novel, to the best of our knowledge, superresolved sensing concept aiming to improve the resolution of temporal signals obtained by applying space multiplexing. The system’s temporal resolution is limited due to the sensor’s time averaging. The proposed superresolution technique overcomes this time average and can therefore increase the system’s temporal resolution. In addition, we also show how to increase the temporal sampling rate, which also affects the temporal resolution. The proposed concept requires that the object will be fixed in space in order to apply the space multiplexing. It can especially be relevant for superresolving laser-based time-of-flight sensors and images as well as light detection and ranging (lidar) devices.
