摘要： Identifying 3D objects A method for identification of 3D objects comprises illuminating at least part of a 3D object with electromagnetic radiation, spectroscopically obtaining spectral data for one or more regions of the 3D object, and generating, at a data processing apparatus, an identification result for the 3D object using a trained machine learning model. The trained machine learning model processes the obtained spectral data for the one or more regions to generate one or more model outputs from which the identification result is derived.

摘要： A method for physical random number generation includes the steps of: modulating the gain of a vertical-cavity surface-emitting laser periodically from the lower threshold to the upper threshold and back; maintaining the gain per round trip positive for a longer period than the round trip time of the cavity; maintaining the net gain per round trip negative for a longer period than the round trip time of the cavity, in order to create optical pulses of random amplitude; detecting the optical pulses; converting the optical pulses into electrical analog pulses; and digitising the electrical analog pulses into random numbers.

摘要： A method is provided for that includes representing a random number and a threshold as a sequence of bits and comparing the sequence of bits representing the random number with the sequence of bits representing the threshold on a bit-wise basis. The most significant bit of the sequence of bits representing the random number is compared with the most significant sequence of bits representing the threshold. If the bits are not equal, deciding that the random number is larger or smaller than the threshold. If the bits are equal, comparing the immediately following bit in the sequence of bits representing the random number with the immediately following bit in the sequence of bits representing the threshold, and repeating this until the bit of the random number does not equal that of the threshold is reached or until all bits have been compared and found to be equal.

摘要： The present invention relates to a method for obtaining an n-type doped metal chalcogenide quantum dot solid-state element with optical gain for low-threshold, band-edge amplified spontaneous emission (ASE), comprising: —forming a metal chalcogenide quantum dot solid-state element, and —carrying out an n-doping process on its metal chalcogenide quantum dots to at least partially bleach its band-edge absorption, which comprises: —a partial substitution of chalcogen atoms by halogen atoms, in the metal chalcogenide quantum dots, and/or —a partial aliovalent-cation substitution of bivalent metal cations by trivalent cations, in the metal chalcogenide quantum dots; and —providing a substance on the metal chalcogenide quantum dots, to avoid oxygen p-doping. The present invention also relates to the obtained n-type doped metal chalcogenide quantum dot solid-state element, a method for obtaining a light emitter with that n-type doped metal chalcogenide quantum dot solid-state element, and the obtained light emitter.
