Image sharpening

Deconvolution microscopy achieves the same Image-sharpening effect as confocal scanning microscopy but through a different process. In this method, Images from consecutive focal planes of the specimen are collected. A separate focal series of images from a test slide of subresolution size (i.e., 0.2 (jim diameter) bead are also collected. Each bead represents a pinpoint of light that becomes an object blurred by the imperfect optics of the microscope. Deconvolution...

Of the above Na LGS/AO systems, only 4 have obtained sharpened images, namely those at Lick, MMT, Calar Alto and most recently Keck. They show that the technology is available today to deploy LGSs, but a substantial amount... 

Kernels may be adapted for sharpening boundaries or increasing the contrast between structures in an image, as in a Laplacian kernel. 

Histochemists are usually aware of the use of focus knobs, used to sharpen the image of the specimen, but are frequently unaware of adjustments to the condenser...
