Title: **Innovations of Albert Stephan Bergendahl**

Introduction

Albert Stephan Bergendahl, an accomplished inventor based in Underhill, Vermont, has made significant contributions to the field of technology, particularly in imaging systems. With a total of eight patents to his name, his work demonstrates innovation and practical application in complex areas like radiation-sensitive mediums.

Latest Patents

Bergendahl's latest patents include an intricate method and system for controlling the relative size of images formed. This method involves exposing a radiation-sensitive medium through a mask while utilizing an imaging system that accounts for depth of focus to manage pattern-dependent distortion. The core steps of this process are as follows: first, providing the radiation-sensitive medium within the imaging system's depth of focus; second, delivering radiation to this medium through the mask; third, positioning the radiation-sensitive medium entirely outside the depth of focus; and finally, again exposing the medium via the mask. Notably, corrections are made by working outside the depth of focus, where the mask functions as a gray-scale mask, allowing the amount of light passing through to depend on the transmission strengths of the mask's pattern regions.
