    Abstract: A spectral camera for producing a spectral output is disclosed. The spectral camera has an objective lens for producing an image, a mosaic of filters for passing different bands of the optical spectrum, and a sensor array arranged to detect pixels of the image at the different bands passed by the filters, wherein for each of the pixels, the sensor array has a cluster of sensor elements for detecting the different bands, and the mosaic has a corresponding cluster of filters of different bands, integrated on the sensor element so that the image can be detected simultaneously at the different bands. Further, the filters are first order Fabry-Perot filters, which can give any desired passband to give high spectral definition. Cross talk can be reduced since there is no longer a parasitic cavity.

    Abstract: An optical mechanism for a miniaturized spectrometer comprises an input unit, an upper waveguide plate, a lower waveguide plate, and a miniature diffraction grating. The input unit is used to receive an optical signal and direct the optical signal to the interior of the optical mechanism. The upper waveguide plate has a first reflective surface. The lower waveguide plate having a second reflective surface aligned substantially parallel to the upper waveguide plate. The first reflective surface is located opposite to the second reflective surface. An optical channel is formed between the first reflective surface and the second reflective surface, so that optical signal from the input unit can travel in the optical channel. The miniature diffraction grating separates the optical signal transmitted in the optical channel into a plurality of spectral components and directs the spectral components to an image capture module at an end of the miniaturized spectrometer.

    Abstract: Embodiments of the invention provides methods and systems for synthesizing optical signals with high frequency stability. Using a set of external optical signal manipulators and control systems, embodiments of the invention enhance the resolution of any frequency reference and thereby alleviates the needs for ultra-high-Q cavities in frequency-stable optical signal synthesis. The invention consequently improves the performance of any optical signal generator by a substantial margin, while maintaining the system complexity and power dissipation at levels comparable to the original systems.

    Abstract: In a spectroscopic module 1, a flange 7 is formed integrally with a diffraction layer 6 along a periphery thereof so as to become thicker than the diffraction layer 6. As a consequence, at the time of releasing a master mold used for forming the diffraction layer 6 and flange 7, the diffraction layer 6 formed along a convex curved surface 3a of a main unit 3 can be prevented from peeling off from the curved surface 3a together with the master mold. A diffraction grating pattern 9 is formed so as to be eccentric with respect to the center of the diffraction layer 6 toward a predetermined side. Therefore, releasing the mold earlier from the opposite side of the diffraction layer 6 than the predetermined side thereof can prevent the diffraction layer 6 from peeling off and the diffraction grating pattern 9 from being damaged.

    Abstract: A system for measuring an sample includes an illumination source providing electromagnetic radiation pulses at a selected temporal frequency. A microscope focuses the radiation to interact with the sample and produce resultant electromagnetic radiation. A disperser disperses wavelengths of the resultant radiation onto optical sensors, and respective resonant amplifiers amplify signals having the selected temporal frequency. Optical detection apparatus includes the optical sensors, resonant amplifiers, and disperser. The resonant amplifiers amplify portion(s) of their inputs having a selected temporal frequency and attenuate other portion(s). A method of analyzing constituents of a sample includes contemporaneously irradiating the sample with narrowband light and broadband light, the optical power of either modulated at a selected temporal frequency; dispersing wavelengths of resultant light across the optical detectors; and filtering respective signals from the optical detectors to provide spectrum data including signals corresponding to the selected temporal frequency.
