Dv. Baranov et al., Characteristics of the differential heterodyne microscope, studied by means of a periodic test structure, J OPT TECH, 68(4), 2001, pp. 297-300
The transfer function of a differential heterodyne microscope is determined
. using a metallized periodic test structure. Its sensitivity to changes in
the parameters of the object is investigated. (C) 2001 The Optical Society
