Title: Irwin J Abramovitz: Innovator in Optical Technology
Introduction
Irwin J Abramovitz is a notable inventor based in Baltimore, MD (US), recognized for his contributions to optical technology. He holds a total of 10 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Among his latest inventions is an optical correlator and method of using the same. This apparatus includes a first light modulator for modulating a first light beam with a signal, and a second light modulator for modulating a second light beam with a reference signal. It features first lens means positioned in the optical path of the second light beam, which introduces horizontal magnification/demagnification that varies with respect to a vertical direction. Additionally, a beam combiner is used to combine the first and second light beams, along with photodetecting means for detecting the combined light beam received from the beam combiner. This apparatus is capable of processing 50 to 100 billion operations per second, which is essential for true Doppler processing of SONAR signals.
Another significant patent is for a node for a grid-type single mode fiber optic local area network. This apparatus processes data packets within a grid-based mesh network, which has a plurality of nodes at the intersections of data transmission links. It can determine if an incoming data packet has previously been re-transmitted through a particular node or has a wavelength of a data packet currently being processed. The apparatus includes tunable filters that block a data packet from being re-transmitted if it has such a wavelength or was previously re-transmitted through the nodes.
