TDK showcased at CEATEC an ultra-thin meta-optic reflector designed for retinal projection smart glasses. The prototype is monochrome green with 750p resolution and a 45-degree diagonal field of view. The reflector is just 150 nanometers thick and achieves 80% visible-light transmittance. TDK plans to launch a green version by the end of 2026, a full-color version in May 2027, and to begin mass production within a few years.
Why we recommend it: The original article gives thickness, transmittance, field of view and a mass-production timeline, useful for comparing the retinal projection approach with waveguide routes.

The High-precision Main Greenhouse gas Imaging instrument (HMI) aboard the Pujiang-4 satellite began imaging on September 27 and downlinked its first data. The instrument's developer, Xiong Wei's team at the Anhui Institute of Optics and Fine Mechanics (AIOFM), conducted a preliminary assessment showing that the payload's functions and performance meet design requirements. HMI uses an information modulation technique combining spatial imaging and spectral interferometry; in a 520 km orbit it acquires hyperspectral data with a 30 km swath, spatial resolution better than 400 m, and spectral resolution better than 0.125 nm. Based on the first data, the team preliminarily estimated the methane emission rate of the Bogatyr open-pit mine in Kazakhstan at about 27.52±1.70 tons per hour.
Why we recommend it: The original article gives HMI's swath width, spatial resolution and spectral resolution, and uses the first data to estimate methane emission rates at a mining site, showing the on-orbit performance of the combined spatial imaging and spectral interferometry scheme.
