Microscanning

Microscanning is a method for increasing resolution of digital cameras.

With the color co-site sampling identically colored pixels in several frames of the specimen, obtained by moving the sensor with a piezo mechanism in a regular raster, are combined to a sharp resulting image.

The detector, however, can also be translated by a fraction of the dot pitch: this way also the interstitial space between sensor pixels gets scanned and the number of pixels in the final image is increased.

It increases with the aperture of the optical system and is inversely proportional to its magnification.

As a result, a low-resolution camera with 500 lines would be enough for an 100X objective with 0.9 aperture.
