Computed-tomography imaging spectrometer performs snapshot imaging spectrometry.

New nitride-based microsensors are being developed for extreme environments.

Membrane encapsulation technologies will enable spectrometers that function at ambient pressures.

New technologies for in situ applications are designed to enhance the performance of conventional systems. These utilize special machining or uniquely integrated components to accomplish specific tasks.

Some of the new technology examples include: CTIS or computed-tomography imaging spectrometer which performs snap-shot imaging as well as spectrometry; microheater integrated GaN/AlGaN high electron mobility transistor (HEMT) sensor uses the modulation of the two-dimensional electron gas in the interface to detect chemical species adsorbed onto the gate electrode; and finger-printing of gaseous species is accomplished by using a microheater to achieve temperature-dependent desorption spectroscopy. These sensors can operate in extreme environments because of the material properties and are useful for remote detection of hazardous chemicals.

The Atmospheric Electron X-ray Spectrometer or AEXS is a thin silicon nitride membrane encapsulated electron gun with an X-ray fluorescence detector. This is an in situ instrument to detect the elemental composition of pristine samples such as rocks on planetary surfaces. The operation involves shooting energetic electrons at a desired sample and detecting the resulting characteristic X-ray fluorescence. The thin nitride membrane preserves the ultra-high vacuum inside the electron gun cavity. An advanced version of the same uses carbon nanotube cold cathodes to save mass, volume and operating power.
