Evaluate depth of field limits of fixed focus lens arrangements in thermal infrared
The full text of this paper is available at the SPIE Digital Library.
The desire to implement lens arrangements without a focusing mechanism demands a deeper quantification of the Depth of Field problem. A new approach avoids the classic “accepted image blur circle”.
Very often, basic functions like recognition or detection of specified targets are tested for a certain lens. But what is the impact of changing the lens for one with a more detailed field of view? The necessary narrow field lenses tighten the Depth of Field problem. A calculation methodology will be presented to transfer depth of field results from an approved lens with a certain focal length and F/number to another lens.
