Abstract: A smartphone is adapted for use as an imaging spectrometer, by synchronized pulsing of different LED light sources as different image frames are captured by the phone's CMOS image sensor. A particular implementation employs the CIE color matching functions, and/or their orthogonally transformed functions, to enable direct chromaticity capture. A great variety of other features and arrangements are also detailed.

Abstract: Integrated spectroscopy systems are disclosed. In some examples, integrated tunable detectors, using one or multiple Fabry-Perot tunable filters, are provided. Other examples use integrated tunable sources. The tunable source combines one or multiple diodes, such as superluminescent light emitting diodes (SLED), and a Fabry Perot tunable filter or etalon. The advantages associated with the use of the tunable etalon are that it can be small, relatively low power consumption device. For example, newer microelectrical mechanical system (MEMS) implementations of these devices make them the size of a chip. This increases their robustness and also their performance. In some examples, an isolator, amplifier, and/or reference system is further provided integrated.

Abstract: An optical unit has a filter member that disperses transmitted light and a photodetector that has light receiving elements. The filter member has a light transmissive substrate, protrusions including a first metallic material and formed on one surface of the substrate, and a metal film including a second metallic material having a refractive index higher than that of the first metallic material and formed so as to cover the protrusions as well as the one surface of the substrate. The metal film located between adjacent protrusions can be a diffraction grating and the protrusions can be waveguides. At least one of the grating cycle of the diffraction grating, the height of the protrusions, and the thickness of the metal film is set to a value different for each portion such that a wavelength of light transmitted through the filter member changes for each portion.
