摘要： Devices and methods of the present technology utilize wavelength-dependent transmittance of 2D materials to identify the wavelength of an electromagnetic radiation. A wide range of 2D materials can be used, making possible the use of the technology over a large portion of the electromagnetic spectrum, from gamma rays to the far infrared. When combined with appropriate algorithms and artificial intelligence, the technology can identify the wavelength of one or more monochromatic sources, or can identify color through the use of a training set. When applied in an array format, the technology can provide color imaging or spectral imaging using different regions of the electromagnetic spectrum.

摘要： Provided is a measurement device including a spectroscope, a movement mechanism configured to relatively move the spectroscope along a first direction with respect to the measurement target, and one or more processors configured to execute detecting a measurement error indicating that spectroscopic measurement processing by the spectroscope is not executed normally, and controlling the spectroscope and the movement mechanism, in which the one or more processors, when the measurement target is a plurality of color patches arranged along the first direction, cause the spectroscope to execute first measurement processing of measuring light with a specific wavelength set in advance while relatively moving the spectroscope in the first direction to acquire a measured value with respect to the specific wavelength obtained by the first measurement processing and a position of the spectroscope, and when the measurement error is detected, move the spectroscope to a position where an amount of variation of the measured value is greater than or equal to a threshold value in a second direction opposite to the first direction and then move the spectroscope in the first direction.

摘要： Examples of a method and a system measure colorimetric data of a set of color samples deposited on a reference substrate and on at least one further substrate having distinct colors from one another. Based on the measured colorimetric data, estimate functions are applied for mapping between the colorimetric data of the color samples deposited on differently colored substrates.

摘要： Wearable spectroscopy systems and methods for identifying one or more characteristics of a target object are described. Spectroscopy systems may include a light source configured to emit light in an irradiated field of view and an electromagnetic radiation detector configured to receive reflected light from a target object irradiated by the light source. One or more processors of the systems may identify a characteristic of the target object based on a determined level of light absorption by the target object. Some systems and methods may include one or more corrections for scattered and/or ambient light such as applying an ambient light correction, passing the reflected light through an anti-scatter grid, or using a time-dependent variation in the emitted light.

摘要： A multispectral sensor array can include a combination of ranging sensor channels (e.g., LIDAR sensor channels) and ambient-light sensor channels tuned to detect ambient light having a channel-specific property (e.g., color). The sensor channels can be arranged and spaced to provide multispectral images of a field of view in which the multispectral images from different sensors are inherently aligned with each other to define an array of multispectral image pixels. Various optical elements can be provided to facilitate imaging operations. Light ranging/imaging systems incorporating multispectral sensor arrays can operate in rotating and/or static modes.

摘要： The method includes inputting a specification of a desired combination of a first component and a second component of a composition, wherein the components are a solid and a dispersant, via a user interface of a computer system; carrying out a database query with the desired combination of the first component and the second component as the search criterion, wherein in the case where the database query supplies a known composition that meets the search criterion, the known composition is output, wherein in the opposite case, a further database query of a composition including the first component and the second component, serving as the search criterion, is carried out to find a candidate composition that includes one of the two components as well as a substitute component instead of the other component; and carrying out further steps for generating the formulation and outputting the composition.

In an embodiment, a method for calibrating a camera includes recording a digital image of a piece of calibration information on a fibre from a plurality of fibres from natural hair or fibres that resemble natural hair by employing a camera. The fibre is identified in the digital image by employing a marker. A plurality of colour values are determined for a plurality of reference colours as the calibration information on the fibre in the digital image, wherein a reference colour value is assigned to each reference colour. The respective determined colour value for the plurality of the determined colour values is assigned to the respectively assigned reference colour value for the plurality of reference colour values.
