Abstract: Exemplary apparatus for method for forming at least one spectral encoding endoscopy configuration. For example, it is possible to modify a spacer configuration and an lens optics configuration to have respective predetermined lengths, and also to modify a dispersive optics configuration to have a further predetermined length. Further, the modified spacer and modified lens optics configurations can be attached to one another to form a combined spacer-lens optics configuration. The modified dispersive optics configuration can be attached to a substrate to form to form a grating substrate configuration. Additionally, the combined spacer-lens optics configuration can be connected to an optical fiber, and the modified attached dispersed optics configuration can be connected to the modified attached lens optics configuration to form the spectral encoding endoscopy configuration(s) which can extends along a particular axis. The dispersive optics configuration can be modified to be at a predetermined angle with respect to the particular axis.

Abstract: A spectrometer includes a light source that emits a beam into a sample volume comprising an absorbing medium. Thereafter, at least one detector detects at least a portion of the beam emitted by the light source. It is later determined, based on the detected at least a portion of the beam and by a controller, that a position and/or an angle of the beam should be changed. The beam emitted by the light source is then actively steered by an actuation element under control of the controller. In addition, a concentration of the absorbing media can be quantified or otherwise calculated (using the controller or optionally a different processor that can be local or remote). The actuation element(s) can be coupled to one or more of the light source, a detector or detectors, and a reflector or reflectors intermediate the light source and the detector(s).

Abstract: A variable wavelength optical filter module according to the present invention includes a package, a variable wavelength optical filter, and a detector. The package includes a reflection part (reflecting faces) in the inside of the package. The variable wavelength optical filter is disposed in the inside of the package and includes a first reflecting plate and a second reflecting plate facing each other, with a clearance between the first reflecting plate and the second reflecting plate being variable. The detector is disposed in the inside of the package and detects a ray of light having passed through the variable wavelength optical filter. Then, the variable wavelength optical filter and the detector are disposed on the opposite side to the reflection part (reflecting faces). The ray of the light incident into the inside of the package via the variable wavelength optical filter enters the detector via the reflection part (reflecting faces).

Abstract: A spectrometer system may be used to determine one or more spectra of an object, and the one or more spectra may be associated with one or more attributes of the object that are relevant to the user. While the spectrometer system can take many forms, in many instances the system comprises a spectrometer and a processing device in communication with the spectrometer and with a remote server, wherein the spectrometer is physically integrated with an apparatus. The apparatus may have a function different than that of the spectrometer, such as a consumer appliance or device.

Abstract: An electronic device may have a display with a cover layer. An ambient light sensor may be aligned with an ambient light sensor window formed from an opening in a masking layer on the cover layer in an inactive portion of the display. To help mask the ambient light sensor window from view, the ambient light sensor window may be provided with a black coating that matches the appearance of surrounding masking layer material while allowing light to reach the ambient light sensor. The black coating may be formed from a black physical vapor deposition thin-film inorganic layer with a high index of refraction. An antireflection layer formed from a stack of dielectric layers may be interposed between the black thin-film inorganic layer and the display cover layer.
