Holographic Interferometer for the Study of Phase Media, Which Has Four Output Channels of Different Sensitivity

Figure 2

The scheme of the ordinary Talbot interferometer. Here and are linear one-dimensional gratings, Ob is the phase object, Sc is a screen, z is the distance between gratings and , and is the distance between grating and screen Sc. z and are multiples of . (Here d is the grating period, is the wavelength of the incident light.)
