A one-step fabrication method has been developed to realize graded holographic photopolymer reflection gratings with gradually varied period in the lateral direction, leading to a rainbow-colored reflection image in the same viewing angle. This low-cost rainbow-colored filter can be integrated with detectors or imaging devices to realize compact and portable spectroscopic analyzers.
