Latest Patents

One of his latest inventions is the Optical Particle Detector. This device is designed to simultaneously detect at least two particles within a useful detection volume. The detector features a retina that receives light rays scattered by the particles, along with a dark reticle positioned between the detection volume and the retina. The dark reticle includes optical apertures that allow certain scattered light rays to pass through while blocking others, resulting in distinct scattering diagrams on the retina.

Another significant patent is the Nondispersive Infrared Gas Detection Sensor. This sensor comprises an optical cavity that receives gas and is defined by two opposite ends connected by a portion. It includes a light source that emits infrared light within the cavity and at least one infrared detector to detect this light. The sensor is distinguished by its reflective elements at both ends of the optical cavity, which have a reflection coefficient of 75% or more for any angle of incidence.
