However, these bioinspired sensors lack the high dynamic range (HDR) and asynchronous polarization vision capabilities of the stomatopod visual system, limiting temporal resolution to ∼12 ms and dynamic range to ∼72 dB. To address these challenges, we have developed a polarization sensitive imaging device that provides both synchronous (ie frame based) and asynchronous (ie event based) visual information. The sensor has a dynamic range over 120 dB and has sub-millisecond latency. The event based polarization information is processed with a deep neural network in order to reconstruct angel and degree of polarization data beyond the maximum Nyquist frame rate.
