Abstract

fetched live from OpenAlex

Some novel micro planar optical components (MPOC) and a micro wire grid polarizer are designed and fabricated. As one of the application of MPOC, a device for color recognition is designed and fabricated. Characteristics of mediums like light, silicon dioxide, silicon and polysilicon as well as their interactions with light are discussed. Making use of the theory of optical physics and geometrical optics, the principle of light path control components and the properties of light energy transmission are analyzed. Power loss of MPOC is simulated by specific optics software. Micro wire grid polarizer is designed and fabricated using MUMP technologies with the support of Canadian Microelectronic Corporation (CMC). Different from traditional optical components fabrication process, the fabrication process coming from chip fabrication technology is applied for the first time for making MPOC. Fabrication of MPOC is conducted in micro-fabrication laboratories at Concordia. All devices are fabricated in micron scales and are compatible with optical fibre light coupling. The processes employed here for fabrication of the micro optical components can greatly reduce the components dimensions and decrease the production cost by a mass production supported by the process.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
