Fig. 5.6 General view of a prototype of laser specklometer with the cover removed (a) and mounting
of the blocks of laser specklometer (b): 1—the laser LGN-208A; 2—PMT unit; 3—the laser power
box; 4—the adjusting mechanism; 5—the light guide center; 6—the network transformer; 7—NP
board; 8—the signal processing unit; 9—VP block. Reprinted from [87] with permission
2.1.8. The illuminating head has an easily removable protective glass
as a variant, which should give the possibility to wipe it with
an alcohol–ether mixture, but it is inadmissible to let the liquid
inside the head.
2.1.9. A unit of the photoreceiver consists of a photoreceiver PMT-116:
a voltage divider for PMT power, elements of fixing of the
receiving fiber, an electromagnetic screen-casing.
