Visibility of ghost imaging in a two-arm microscope imaging system

Abstract

Ghost imaging with a classical thermal source is investigated in a two-arm microscope imaging system. The dependence of the imaging visibility on the aperture of the reference lens is discussed. It is shown that by using large apertures, good visibility as well as enhancing resolution can be obtained. The effects from the distance the object is moved away from the original plane are also studied, and one can obtain good visibility with a well-resolved image by changing the distance.

Compressive microscopic imaging with “positive–negative” light modulation

“…To our knowledge, the only previous report on the use of GI in actual microscopy was based on entangled photon pairs, which is a complicated and expensive light source [35]. Ghost imaging with a classical thermal source was studied in a two-arm microscope imaging system but it was only a theoretical simulation with a simple double-slit object [36]. Recently, CS was also applied to microscopy [37,38]; in [38], Studer et al tested their system on a sample of fluorescent beads which were sparsely distributed.…”
