Inertial measurement apparatus arranged to be carried by a carrier vehicle include a chassis, a turntable mounted on the chassis, a first inertial measurement unit mounted on the turntable and connected to an electronic control unit connected to a motor for controlling turning of the turntable, and a second inertial measurement unit secured to the chassis. The control unit turns the turntable through one revolution with periodic alternating motion from a fixed initial angular position of the turntable. The control unit calculates the acceleration of the carrier vehicle from measuring the first inertial measurement unit while the turntable is stationary and from measuring the second inertial measurement unit while the turntable is moving. The control unit reconstitutes an inertial reference frame for each inertial measurement unit and compares the two inertial reference frames to determine a difference and takes account of this difference when calculating the acceleration.

Inertial measurement device

A compact night vision binoculars with a first eyepiece channel and a second eyepiece channel and including: an optical separator (), positioned at the output of a light intensifier tube (); a plane of reflection (') common to the first optical channel (BYZC) and the second optical channel (BCW); a first optical combination comprising two first convergent groups (V, V) positioned on either side of a first reflective angled surface (); a second reflective angled surface (); a second optical combination comprising two second convergent groups (V&#x2032;, V&#x2032;) positioned on either side of the common plane of reflection (&#x2032;); and a third reflective angled surface ().

Night vision binoculars

An optronic observation device including a detector having a photocathode and a sensor arranged to receive an incident light beam. The device also including a switch to position an optical element opposite the detector in the pathway of the incident beam or to retract the optical element and a focusing element to focus an incident ray on the photocathode when the optical element is in a retracted position. When the optical element is positioned opposite the detector, it is able to focus the beam on the sensor and to filter the beam spectrally to block all or part of the wavelengths for which the responsiveness of the photocathode is greater than a given threshold.
