Question

You are hired to design the front end of an imaging system for studying the boundary shapes of
cells, bacteria, viruses, and protein. The front end consists, in this case, of the illumination
source(s) and corresponding imaging camera(s). The diameters of circles required to enclose
individual specimens in each of these categories are 50, 1 , 0.1 , and 0.01 microcenters,
respectively. Can you solve the imaging aspects of this problem with a single light source and a
camera? If your answer is yes, specify the illumination wavelength band and the type of camera
needed. By “type,” we mean the band of the electromagnetic spectrum to which the camera is
most sensitive (e.g., Infrared). Hint, the following energy spectrum is given to help you.

Explanation / Answer

The source of the illumination required to see an object must have wavelength the same size or smaller than the object. Because interest lies only on the boundary shape and not on other spectral characteristics of the specimens, a single illumination source in the far ultraviolet (wavelength of .001 microns or less) will be able to detect all objects. A farultraviolet camera sensor would be needed to image the specimens. (b) No answer required since the answer to (a) is affirmative. also, https://docs.google.com/viewer?a=v&q=cache:Pjn9d5dW6fAJ:www.creatis.insa-lyon.fr/~grenier/wp-content/uploads/teaching/DIP/DIP-Exercise.pdf+You+are+hired+to+design+the+front+end+of+an+imaging+system+for+studying+the+boundary+shapes+of+cells,+bacteria,+viruses,+and+protein.+The+front+end+consists,+in+this+case,+of+the+illumination&hl=en&gl=in&pid=bl&srcid=ADGEESgdOx2vj7GJ5tRueURR7-VGlhsosxdW4Aw8SD5Uit2u4XpuAW8HjjGg4Av5Xn-sSzTK_Uca-XmwfIFNwEQmQ9WVPbUgJuE661TJTkpec9g930rQR7xzn_QWrX1eCrzmTb4HxGmF&sig=AHIEtbSaGCayS21dOIxwe8Ez6CjfBRF-dw
