    dct:description "<p>Development of chip-size remote sensors for measuring atmospheric molecules and meteorology on Earth and on other planets. &nbsp;We specifically target usage on future interplanetary small platforms (e.g. smallsats, small landers).</p><p>The chip spectrometer operates on the principle of heterodyne detection. &nbsp;Heterodyne spectrometers offer ultra-high spectral resolution, without bulky dispersive elements or moving parts, and shot-noise-limited SNR (signal-to-noise ratio). &nbsp;Moreover, the chip spectrometer utilizes microfabrication to produce on-chip arrays wherein each array element (pixel) is a heterodyne spectrometer. &nbsp;Depending on the measurement objective, these on-chip nano-spectrometers can be configured either as spatial imaging pixels to enable imaging, or as spectral pixels for increasing spectral coverage. &nbsp;The chip detector resides in the focal plane of a mini-telescope to detect sunlight that has propagated through the planetary atmosphere. &nbsp;Amplitudes of absorption lines observed in the sunlight indicate molecular abundances, while ratios between different rotational-vibrational lines indicate atmospheric temperatures. &nbsp;Additionally, Doppler shifts in line-center wavelengths indicate wind speeds.</p>" ;
