Abstract: A compact, portable Raman spectrometer makes fast, sensitive standoff measurements at little to no risk of eye injury or igniting the materials being probed. This spectrometer uses differential Raman spectroscopy and ambient light measurements to measure point-and-shoot Raman signatures of dark or highly fluorescent materials at distances of 1 cm to 10 m or more. It scans the Raman pump beam(s) across the sample to reduce the risk of unduly heating or igniting the sample. Beam scanning also transforms the spectrometer into an instrument with a lower effective safety classification, reducing the risk of eye injury. The spectrometer's long standoff range automatic focusing make it easier to identify chemicals through clear and translucent obstacles, such as flow tubes, windows, and containers. And the spectrometer's components are light and small enough to be packaged in a handheld housing or housing suitable for a small robot to carry.

Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.

Abstract: An example method includes receiving a first set of data that includes spectral metrics provided by a spectral acquisition apparatus that obtains the spectral metrics based on interactions of electromagnetic radiation with a sample. The first set of data is processed to obtain a second set of data that includes the spectral metrics. One or more trained models are applied to the spectral metrics or a set of values based on the spectral metrics to obtain a result. Based on the result, either a positive particle of interest detection or a negative particle of interest detection for the particle of interest for the sample is determined. A particle of interest detection notification that indicates either the positive particle of interest detection or the negative particle of interest detection for the particle of interest for the sample may be generated and provided.

Abstract: Systems and methods for color selection are provided. A user device displays room types on a display, receives a room type selection indicating a particular room type, displays types of feelings, and receives a type of feeling selection indicating a particular type of feeling. The user device accesses a lookup table that associates the room types and types of feelings with paint colors such that each possible combination of room type and type of feeling is associated with a subset of paint colors. The user device determines the associated subset of paint colors in the lookup table for the combination of the particular room type and the particular type of feeling and displays the associated subset of paint colors as recommended paint colors for the combination of the particular room type and the particular type of feeling on the display of the user device.

Abstract: Disclosed is a combination of a Fabry-Perot Tunable Filter (FPTF) wavelength selector, an internal reflection element (IRE) capable of measuring Attenuated Total Reflectance (ATR) spectra, and a pressure application element for applying pressure to samples, if needed. The resultant portable and compact device is called an FPTF-ATR spectrometer. The device measures data that can be used to identify chemical species in samples, predict properties of samples, and quantify amounts of chemical species in samples. Also disclosed are methods for using the FPTF-ATR for analyzing samples, especially analyzing compounds containing cannabis, hops, and other chemical species where portable chemical analysis is important.

Abstract: A device running a game based on spectrometer data comprises a spectrometer configured to detect the spectrometer data of a real-life object, the spectrometer data indicating one or more features of the real-life object, and one or more processors configured to receive the spectrometer data of a real-life object from a spectrometer, determine a game object based on the spectrometer data, wherein the game object has one or more attributes corresponding to the one or more of features of the real-life object, and perform one or more actions on the game object based on the one or more attributes of the game object. Spectrometer data of real-life objects can be generated to create game objects and modify game attributes of the game objects, which can bring more fun into gaming, and stimulate the game player's interest and curiosity in exploring the characteristic associated with various objects in real world.
