Ran Tao·Follow8 min read·--In the digital era, visual media holds immense emotional and cultural value. But while new content is vivid and full of color, much of our visual history remains in black and white. DeOldify is an open-source tool that applies deep learning to colorize grayscale photos and videos, allowing us to see history clear and fresh. Unlike some other photo colorizers, DeOldify is self-hosted and designed for personal use, making it both accessible and privacy-friendly.

This Letter proposes a novel, to the best of our knowledge, matrix digitization method for a photonic analog-to-digital converter with phase-shifted optical quantization (PSOQ-ADC). This method overcomes the issues of excessive bit width of the output code and the generation of invalid codes encountered by the traditional direct digitization method. A PSOQ-ADC was fabricated on a lithium niobate on insulator (LNOI) platform, and an experimental platform was built.

1. IntroductionOrdinary optical microscopes are mainly used to observe the surfaces of opaque samples and light-transmitting samples with different transmittances. One characteristic of their imaging is that the entire image is formed on the image plane of the system at the same time.
