    Abstract: A spectra generator having an electrically programmable diffraction grating. There may be a broad band light source that emits light which is diffracted by the grating. Diffracting elements in the grating may be individually adjustable so that generation of a specific spectrum or spectra may be achieved. The diffracting elements may be adjusted according to electrical signals of a program from a computer. The generated synthetic spectra may be used for testing and calibration of spectrometers or other devices. Synthetic spectra may also be used for scene generation and other purposes.

    Abstract: This invention provides apparatus for remote temperature sensing by means of fiber optics in which the sensor is optical and passive, with no electrical power required at the sensor. The temperature-sensing section of the fiber optic makes use of a transparent liquid as core or cladding and in which the transparent liquid has a temperature-dependent index of refraction.
