Abstract: A device of integration of an electric current received on an integration node, includes an operational amplifier, an integration capacitor, and a circuit for modifying an output voltage of the operational amplifier formed by a charge transfer circuit configured to be connected on the integration node and to transfer charges into the integration capacitor. The device also includes a comparison circuit configured to trigger the modification circuit at least once during the integration duration, and a storage circuit configured to store the number of triggerings which have occurred during the integration duration. The received electric current is calculated according to the output voltage as well as to the number of triggerings multiplied by the modification of the output voltage induced by the modification circuit.

Abstract: An infrared sensor includes an assembly of pixels juxtaposed in rows and in columns, each pixel integrating an imaging microbolometer and an integrator assembly. The integrator assembly includes a transistor assembled as an amplifier, and a capacitor assembled in feedback on the transistor between an output node and an integration node. The integration node is connected to a skimming transistor operating as a current mirror with a skimming control transistor offset outside of the pixel. A skimming current flowing through the skimming control transistor is controlled according to the temperature of at least one thermalized microbolometer. The current mirror assembly enables to transmit the skimming current flowing through said skimming control transistor onto the integration node so that the capacitor integrates the difference between a current flowing through the imaging microbolometer and the skimming current.

The distal tip and the barrel are made of glass and the distal tip is provided with a thread, the thread being configured to connect the distal tip to a connecting element having a complementarily shaped internal thread.

Abstract: An optical module (10) is attached in front of an optical outlet (21) of a monostatic or quasi-monostatic laser rangefinder (20), for the purpose of transversely offsetting a laser beam of primary radiation (F) emitted by the optical outlet. In this manner, the risk of damage to an optical sensor (23) of the rangefinder can be avoided.

Abstract: An imaging instrument for controlling a target designation makes it possible to visualise a target designation spot (SP) within a scene (SC), while using only one image sensor. To do this, a filter is arranged on the image sensor, in a restricted area (ZC) of same. The filter makes it possible to increase a contrast and a signal-to-noise ratio for an image of the target designation spot, when a misalignment (DP) is produced in order to bring the image of the target designation spot into the area of the filter.
