You must determine the length and width of one pixel in millimeters. This is often called the pixel spacing or pixel pitch.

Despite these challenges, the research community is optimistic. The fundamental principle of using optical antennas to overcome the classical diffraction limit of light — and to control electrical current at the nanoscale — is a major paradigm shift. As one researcher put it, "should that dawn, these innovations will upend wearables, shrinking screens and projectors to whispers of their former selves".
The most recent innovations go beyond simple area measurement, using new algorithms to extract more sophisticated types of information.
The paper "The global pixel size calibration method for a dual telecentric imaging system based on a sphere array" outlines a revolutionary approach. Instead of a flat grid, this method uses a precise as a calibration target. Advanced algorithms automatically detect the centers of these spheres in the image, calculate the local pixel size for each one, and then create a smooth calibration map for the entire camera sensor. The results are striking: in experimental measurements, this new method reduced the maximum mean absolute error by 60% compared to conventional methods, achieving an error of less than 0.021 mm.
Imagine a 1080p projector small enough to be embedded in the bezel of a laptop, the edge of a smartphone, or even inside a smartwatch. This technology would allow "pop‑up" displays and projection surfaces for impromptu presentations, entertainment, or collaborative work. For example, a smartphone could project a full‑size 1080p screen onto any flat surface without requiring a separate projector.
