Event-based imaging polarimeter simulation with a single DoFP image

An event camera is a neuromorphic vision sensor with a high dynamic range (HDR), high temporal resolution (HTR), low latency, and low power consumption. A polarimeter is an instrument for measuring the state of polarization of light. Currently, most imaging polarimeters are limited in dynamic range and frame rate when used with frame-based cameras. We can establish an event-based imaging polarime-ter using the principle of the event camera to obtain HDR and HTR polarized event streams for processing polariza-tion information. However, because of the short history and high cost of event cameras, developing an event-based imag-ing polarimeter requires substantial resources. We propose an event-based imaging polarimeter simulation method with a single division of focal plane image based on the existing research on event simulation. This method can easily convert existing data into a polarized event stream. It is beneficial to lower the requirement of processing polarized event streams and to create large datasets for deep learning.(c) 2023 Optica Publishing Group
