Scanning radiation sensor with automatic focus control for optimal focus and method |
摘要 |
A scanning radiation sensor (10) automatically focuses a focusable optical system (26) based on the closest distance (C) and the farthest distance (F) of the optical system (26) from a target (12) through means of a focusing controller (44), motor driver (42) and focus motor (40) to obtain an optimum focus for all points along a line between the farthest point (f) and closest point (c).
