Single-Array Multimodal Sensing with Hyperspctral, Polarization and High Accurate 3D Measurements
Project Status: Active (Started: 2004)
Research Description
We presented a novel single-array multimodal sensor that can obtain three-dimensional (3D), hyperspectral, and complete Stokes polarization images of targets from the same viewpoint. The sensor integrates the following components: high accurate 3D measurements via a projection grating phase method; hyperspectral acquisition with the use of an Acousto-Optic Tunable Filter; and complete Stokes polarization acquisition based on Liquid Crystal Variable Retarder. All of the three components share the same set of optical system and the measurements are imaged on a single focal plane array. This design also features adaptive data collection in hyperspectral, polarization and 3D measurements. The precise co-alignment design avoids the problem of multimodal registration and the multimodal adaptive sensing improves the data acquisition efficiency, therefore improves the overall accuracy and efficiency of target detection and recognition.
