Two approaches have been devised to deal with the problem of blurring in light microscopy with thicker samples. Indicate whether each of the following descriptions better applies to confocal design (C) or image deconvolution (D). Your answer would be a three-letter string composed of letters C and D only, e.g. CCD.
( ) It is normally faster.
( ) It requires a higher degree of sample illumination.
( ) It can be used to obtain images from relatively deeper parts of the specimen.
