Abstract: Color information obtained by an optical sensor of a stylus can be displayed at a pen tip of the stylus with good visibility, and visual feedback is provided as a suitable user interface when the color information is transmitted from the stylus to an electronic apparatus. A stylus includes: a trigger signal generating circuit; an optical sensor that detects incident light; a memory circuit that stores color information of the incident light detected by the optical sensor; a color presenting circuit which is disposed at a pen tip of the stylus and which presents a color corresponding to the color information; and a control circuit. The control circuit presents the color information detected by the optical sensor using the color presenting circuit at the pen tip, and controls the color presenting circuit in response to a trigger signal from the trigger signal generating circuit when transmitting the color information to the electronic apparatus.

Abstract: Systems and methods for compact and low-cost vibrational spectroscopy platforms are described. Many embodiments implement deep learning processes to identify the relevant optical spectral features for the identification of an element from a set of elements. Several embodiments provide that resolution reduction and feature selection render efficient data analysis processes. By reducing the spectral data from the full wide-band high-resolution spectrum to a subset of spectral bands, a number of embodiments provide compact and low-cost hardware incorporation in spectroscopic platforms for element identification functions.

Abstract: Various embodiments disclosed herein describe a divided-aperture infrared spectral imaging (DAISI) system that is adapted to acquire multiple IR images of a scene with a single-shot (also referred to as a snapshot). The plurality of acquired images having different wavelength compositions that are obtained generally simultaneously. The system includes at least two optical channels that are spatially and spectrally different from one another. Each of the at least two optical channels are configured to transfer IR radiation incident on the optical system towards an optical FPA unit comprising at least two detector arrays disposed in the focal plane of two corresponding focusing lenses. The system further comprises at least one temperature reference source or surface that is used to dynamically calibrate the two detector arrays and compensate for a temperature difference between the two detector arrays.
