Latest Patents

Two of Lonnoy's latest patents exemplify his ingenuity in optoelectronic systems:

1. **Target Acquisition Optoelectronic System with a Very Wide Field**

This advanced system includes focusing optics with a linear array of photodetectors placed in its focal plane. A double prism is positioned opposite the photodetectors and is servo-controlled for rotation about its longitudinal axis. Additionally, the support of the prism is also servo-controlled for rotation about the optical axis, allowing it to scan approximately 2π steradians. A derotating prism aligned with the optical axis rotates at half the speed of the double prism, which ensures that the image of the target remains fixed in a single direction within the focal plane, regardless of the support's rotations.

2. **Device for Measuring the Heading Error of a Missile**

This device features a dual afocal system designed for the taking-in-charge field (PC) and cruising field (CR). Positioned in front of a double prism, this system operates with a central and a peripheral prism, bonded together with opposing dihedrals at the same angle. When one detector captures the PC field, an adjacent detector views the CR field. An analog switch then seamlessly circulates the signal processing between the PC and CR channels, providing precise measurements of the missile’s heading error.
