Abstract: A method of measuring the spectral properties of broadband waves that combines interferometry with a wavelength disperser having many spectral channels to produce a fringing spectrum. Spectral mapping, Doppler shifts, metrology of angles, distances and secondary effects such as temperature, pressure, and acceleration which change an interferometer cavity length can be measured accurately by a compact instrument using broadband illumination. Broadband illumination avoids the fringe skip ambiguities of monochromatic waves. The interferometer provides arbitrarily high spectral resolution, simple instrument response, compactness, low cost, high field of view and high efficiency. The inclusion of a disperser increases fringe visibility and signal to noise ratio over an interferometer used alone for broadband waves. The fringing spectrum is represented as a wavelength dependent 2-d vector, which describes the fringe amplitude and phase. Vector mathematics such as generalized dot products rapidly computes average broadband phase shifts to high accuracy. A Moire effect between the interferometer's sinusoidal transmission and the illumination heterodynes high resolution spectral detail to low spectral detail, allowing the use of a low resolution disperser. Multiple parallel interferometer cavities of fixed delay allow the instantaneous mapping of a spectrum, with an instrument more compact for the same spectral resolution than a conventional dispersive spectrometer, and not requiring a scanning delay.

Also disclosed are related methods for detecting images and rendering images using such devices and apparatus. Such devices, apparatus and methods allow improved accuracy and sensitivity of radiation detection without having to use a cooler. A representative conversion device includes a substrate and a suspended portion attached to the substrate via a leg portion. The conversion device includes a radiation-absorbing film that receives and absorbs and incident invisible radiation (e.g., UV, IR, or X-rays) and generates heat from the absorbed radiation. The suspended portion includes a displaceable member that exhibits a displacement with respect to the substrate. The displacement also imparts a change to an incident readout light flux in accordance with the magnitude of the displacement. The change to the readout light is detected and used to form an image.

Abstract: An optical fiber environmental detection system comprising an interferometer, a broadband light source and a detector is disclosed. The interferometer further comprises a thin core fiber, a first single mode fiber and a second single mode fiber; wherein the thin core fiber is coupled to the first and second single mode fiber via a first junction and a second junction respectively. When an emission light reaches the first junction, high-order cladding modes will be excited. The excited cladding modes will interfere with the core mode at the second junction. The interferences determine the intensity maximum or minimum of the received signal. When there is an ambient environmental change, a shift of the received signal would be induced. According to the shift, environmental change, for instance ambient temperature, could be determined.

Abstract: A cavity thermal detector assembly is presented that allows both tunable narrowband and broadband operation. This allows for high light efficiency, low thermal time constant, and flexibility in designing the optical path. The thermal detector/filter layers are part of the top mirror or mirrors of a Gires-Tournois-type optical cavity and provide absorption and reflection that can be adjusted to the desired width and position of the detected band. Tuning, if desired, can be achieved by applying micromechanical methods. Broadband operation may be achieved by bringing the sensor close to the bottom mirror. In this mode, the sensor or its supports may or may not touch over a small area.
