Under Microscope

It's another world under the microscope.

These are images of a house moth under the microscope. Microscopic observations of non-planar objects are challenging since the focus depth of highly magnified images are particularly shallow. This issue is tackled by a method called extended focus depth imaging. In this method, several images of the same location of the object are taken with different adjustments of the objective and the ocular focusing on distinct parts of the object in a sequence. Later, with advanced algorithms portions of the image with higher sharpness are preserved in every image and stitched into a collage that is sharp at every depth. These moth images also are a combination of several locations for extended context. Each of these images require careful combination and size optimization of over fifty images.
