摘要： A highly dispersive single-mode hybrid optical fibre (1900) located in one of a reference arm or a probe arm of an optical interferometer, the hybrid fibre (1900) comprising at least two optical fibres (1902, 1902), at least one of the at least two optical fibres having a different core diameter and different dispersive characteristics to at least one other optical fibre of the at least two optical fibres, wherein the at least two optical fibres are end-to-end fused to form a hybrid optical fibre, and wherein each one of the at least two optical fibres has a length based on the core diameter of that optical fibre relative to a central wavelength of a light beam passing through the hybrid optical fibre and a target GDD per unit length based on the target length of the hybrid optical fibre, wherein the hybrid optical fibre adds an additional GDD value compared to an optical fibre in the other one of the reference arm or probe arm of the optical interferometer.

摘要： A 3-dimensional measurement apparatus includes: a projection device configured to project a stripe pattern of a sinusoidal brightness distribution to an object; an imaging device configured to image the object to which the stripe pattern is projected; and a control device configured to control the projection device and the imaging device. The control device includes a pattern generation unit, an image data acquisition unit, a phase value calculation unit, a collation unit, and a 3-dimensional shape calculation unit. The collation unit collates a first phase value with a second phase value and specifies noise. The 3-dimensional shape calculation unit calculates a 3-dimensional shape of an object based on the first phase value in which the noise is determined not to be contained.

摘要： An electronic apparatus is disclosed. The electronic apparatus includes a first sensor configured to obtain a color image, a second sensor configured to obtain a depth image, a memory storing a neural network model, and a processor configured to, based on a first color image being received from the first sensor, obtain a first region of interest by inputting the first color image to the neural network model, and identify whether a distance between an object included in the first region of interest and the electronic apparatus is less than a threshold distance.
