Convex Curved Single-Chip Thin-Film Image Sensors for Distortion-Free Multilens Panoramic Imaging
Abstract
We propose a concept of convex curved single-chip thin-film image sensors for distortion-free multilens panoramic imaging. A flexible thin-film transistor active pixel sensor (320 × 240 pixels) with an organic photoconductive film was fabricated using a 15-µm-thick film substrate and laminated on a convex curved plate with a radius of curvature of 16.3 mm to form a curved image sensor. By combining the curved sensor with concentrically arranged three lenses, we successfully obtained wide-angle images without distortions by a simple 'cropping and tiling' process.Keywords
