Abstract: A system includes a focal plane array (FPA), support structure, optical assembly, flexing structure, and drive actuator. The FPA includes multiple pixels. The FPA captures an image as image data during an integration time interval. The optical assembly is fixed to the support structure and forms an image of a scene at the FPA. The flexing structure is mechanically coupled to both the support structure and the FPA, and allows the FPA to move relative to the support structure. The actuator is mechanically coupled to the FPA, and drives the FPA to move relative to the support structure. Some FPA have all readout elements arranged in a first regular grid with constant spacing, while some detector elements are on that grid and other detector elements are on a different grid offset by less than the constant spacing to provide sub-pixel resolution.

Abstract: An optical device includes a waveplate sandwiched between first and second polarizers and is arranged to receive light emanating from an object or object image that is in motion relative to the optical device. A detector array includes one or more detector elements and is optically coupled to receive light from the second polarizer. Each detector element of the detector array provides an electrical output signal that varies according to intensity of the light received from the second polarizer. The intensity of the light is a function of relative motion of the object or the object image and the optical device and contains spectral information about an object point of the object.

Abstract: An imager contains an image sensor with laterally varying spectral response. The imager is scanned over a scene or object to form a spectral image. The spectral responses are repeated at different positions in the field of view so as to reduce the effect of scene nonidealities, such as angle dependence or temporal variation, on the spectral image data. A part of the image sensor may be used for conventional two-dimensional imaging. This part of the image sensor may be used to estimate the scene geometry and scan movement, enabling further improvement in the spectral integrity.

Abstract: Light from a direction (D) different from a predetermined direction is reflected by a tapered surface (21) so as to enter an optical fiber (4) for guiding light entering along the predetermined direction to an appliance. Light from the desired direction (D) may thereby be reflected by the tapered surface (21) according to the angle of the tapered surface (21) and may be made to enter the optical fiber (4). Accordingly, even in a case where the installation position of an optical measurement probe (1) is limited, if the angle of the tapered surface (21) is appropriately set, light from the desired direction (D) may be made to enter the optical fiber (4).

Abstract: A gas measurement system for measuring the concentration of gaseous and/or vaporous components of a gas mixture by means of a color change of at least one reaction substance on a reaction support unit, which is arranged in at least two light permeable channels in such a manner that the color change on the reaction substance can be detected at low expense on a large number of separate positions. The detecting unit which detects the color change can be designed as a digital camera with an electronic image converter or image sensor, and an imaging optics system (e.g., a lens system). Related systems, methods, apparatus, and articles are also described.
