Abstract: A housing has a partition wall constituting a wall surface of a sample chamber, and an interferometer chamber accommodating an optical component is formed on an opposite side to the sample chamber with respect to the partition wall. A window member is attachable to and detachable from an opening formed in the partition wall, and transmits light between the sample chamber and the interferometer chamber. The lid member is attachable to and detachable from the window member, and internally has a moisture absorbent accommodating space for accommodating a moisture absorbent. The lid member engages with the window member attached to the opening from a side of the sample chamber, so that the side of the sample chamber of the window member is covered with the lid member, and the moisture absorbent accommodating space is set in a substantially airtight state.

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: The inventive phase measuring device includes a first A/D converter 2 that digitizes a first periodical input signal X at each predetermined sampling timing and outputs the resultant signal as a digital signal Xd, a first zero-crossing identification means operable to detect a sign of Xd, a counting processing unit 4 that counts a difference in the number of times of zero-crossing detection by the first zero-crossing identification means and calculates the difference at each sampling timing, and a fraction processing unit 5 that computes a fraction of the number of times of zero-crossing detection on the basis of Xd at sampling timings immediately before and immediately after determination of zero-crossing by the first zero-crossing identification means. An averaging processing unit 6 performs averaging by adding up and totalizing the outputs from the counting processing unit 4 and the fraction processing unit 5, thereby computing a phase. The inventive device thus implements a digital phase measuring device and a digital phase difference measuring device that allow input of periodical signals in a wide frequency range and that are capable of accurate and real-time measurement.

Abstract: A spectral imaging system includes a spectrometer and an optics imaging system. The spectrometer is operable for generating spectral signatures of objects from a scene. The optics imaging system is operable to generate six or more responses from the same scene. Each of the six or more responses represents different spectral content of the objects in the scene. The responses generated by the optics imaging system can be used to generate a hypercube using spectral reconstruction techniques. In an embodiment, the spectral imaging system could be implemented as part of a mobile phone.
