Technology Database  Optics BINOCULARS WITH A BUILT-IN IMAGE STABILIZATION SYSTEM
Binoculars
With A Built-in Image Stabilization System
Binoculars with a built-in image
stabilization system (BS) provide a means of conducting steady and high-quality
visual observations from moving transport facilities by compensating for
external vibration and hand tremor.
The new binoculars differ from
analogs in their wide field of vision, high magnification, and greater lens
speed. They may be used for observations from swiftly moving transport
facilities (helicopters, airplanes, motor vehicles, etc.), for observing such
objects, and for observations in the conditions of poor illumination of objects.
The scientific and technical
novelty of the binoculars consists in the use of a system of movable mirrors,
which produce a high-quality image despite the changing spatial positions of the
binoculars themselves and the observed object. In their principal parameters (see
Table) and in their production and cost characteristics (estimated for an output
of 1000 binoculars a year), the proposed binoculars have a twofold superiority
over the best analogs in the world.

The proposed binoculars should be
much in demand with law-enforcement agencies, traffic inspectors, coastguard
services, aerial environmental monitoring services, search-and-rescue services
at sea, and other consumers conducting observations in difficult illumination
conditions and from unstable platforms. The multifaceted market for such
binoculars and their low cost compared with the cost of their best analogs,
which have inferior performance features, provide highly positive prospects for
the profitability of their production.
