Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical imaging technology, and in particular to an imaging device and method based on multi-dimensional optical perception. BACKGROUND

[0002] Traditional optical imaging technology is mainly based on intensity information, and the detection, identification and recognition ability of the target will decrease sharply in complex environments (such as fog, smoke, underwater, complex background camouflage). Multi-dimensional optical perception technology, that is, simultaneously acquiring spectral information, polarization information, phase information and the like of the target, provides a new solution path for improving the target recognition ability in complex environments.

[0003] Most of the existing multi-dimensional optical perception systems are multi-aperture spectral systems. Such systems use multiple independent imaging sensors, each of which is configured with different filters, polarizers or spectral prisms in front of each sensor to receive different physical quantities of optical information. The superposition of multiple lenses, sensors and independent electronic systems results in a huge volume, weight and power consumption of the overall system, making it difficult to deploy on unmanned aerial vehicles, handheld devices or satellite platforms with strict load requirements, and greatly limiting its application scenarios. At the same time, multi-sensor multi-aperture registration errors make it difficult to ensure parallel light paths, resulting in multi-physical quantity acquisition deviations. SUMMARY
