Title: Olivier De Witte: Innovator in Laser Technology
Introduction
Olivier De Witte is a notable inventor based in Gif sur Yvette, France. He has made significant contributions to the field of laser technology, holding a total of 6 patents. His work has focused on innovative applications of lasers, particularly in detection and excitation technologies.
Latest Patents
One of his latest patents involves a gas laser excited by a transverse electrical discharge triggered by an X-ray generator. This generator is directly connected to an electrode within a hollow cathode, emitting electrons under a field effect to generate X-rays. The generator supplies between 50 to 100 kV with a rise time of less than 10 nanoseconds. The rapid creation of X-rays subsequently generates electrons in the active medium, triggering a discharge between the anode and cathode. This process is pre-applied at a voltage level below the breakdown voltage of the active medium.
Another significant patent is for an apparatus designed to detect an enemy's infrared camera. This apparatus includes a continuous infrared laser directed towards the camera, a receiver for the infrared signals sent by the camera, and a processing circuit capable of determining a delay time. The system creates a bright spot on the camera screen, representing a picture of a dummy object displaced from the apparatus, effectively overshadowing the true location of the apparatus. This invention has applications in military technology, particularly for detecting infrared cameras placed on tanks.
