is supposed that using monochromatic laser radiation will give the possibility to detect
more accurately pathological formations, areas of inflammation, etc. [269–272].
Another difficulty was connected with providing immobility and necessary
contrast of the interference pattern during registration of living movable tissue, and
it was eliminated through reducing the exposure time [273–275]. Thus, for example,
there are methods of holographic recording of a living object, i.e., fast processes,
which are based on deliberate frequency change in the object and the reference
wave [273]. These methods give the possibility to register the interference pattern of
movable objects without reducing the duration of exposure. Another possibility of
hologram recording is the local reference wave method [274, 275], which consists
in that the reference wave is formed as a part of the object one. This leads to an
automatic phase modulation of the reference wave. In the case when the holographic
object is in motion as a whole, all or any part of the focused reference wave can
