Abstract: Problem to be solved by the invention: The present invention aims at providing a motion discrimination system and a method for motion discrimination capable of real-time and accurate detecting motions of an object. Means to solve the problem: A motion discrimination system according to the present invention comprises: a detecting means for outputting different analog values corresponding to motion of an object in each of a plurality of detecting areas; a data processing means for processing the analog values output corresponding to the motion in each of the plurality of detecting areas to quantized time-series data; and a motion discrimination means for outputting a motion discrimination result using a motion discrimination model in which the time-series data are inputs and types of motions are outputs. The motion discrimination model is a neural network in which the time-series data are inputs to input nodes and the types of motions are outputs from output nodes. Selected drawing: FIG.

Abstract: A plastic optical fiber continuous optical amplifier for continuously amplifying signal lights includes an exciting light tube with a double tube structure formed of an inner tube and an outer tube, and a plastic optical fiber (POF) coaxially provided inside the inner tube of the exciting light tube. The POF includes a core having an induced emission material therein and a larger refractive index, and a clad for holding the core and having a smaller refractive index than that of the core. The core and the clad are coaxially provided to the POF. It is preferable that electrodes of the exciting light tube have a ring shape to effectively excite.
