“…Other promising technologies, such as δ-doped chargecoupled devices, have been recently demonstrated and offer quantum efficiencies near unity in the visible and UV wavelength regions [20,21]. We plan to evaluate these technologies in future work toward developing a compact and sensitive UVRR instrument suitable for planetary science applications.…”

We report on the development of a compact and robust instrument for multi-line ultraviolet resonant Raman spectroscopy. This instrument will be able to collect simultaneous full-range (800-4000 cm 1 ) high-resolution Raman spectra resulting from resonance-enhanced excitation at multiple UV laser wavelengths. The resulting matrix of spectra will allow the identification and analysis of several organic chemical compounds of interest for the detection of extraterrestrial life, including amino acids and nucleosides. This instrument is being developed under NASA's Planetary Instrument Definition and Development Program, and we will also discuss its potential contributions to future planetary exploration missions.

“…This limiting condition is known as "critical sampling" or "Nyquist sampling of the optical blur" in the astronomy community. 16 The latter term is not good terminology since the blur diameter consists of all frequencies up to the optical cutoff. When Fλ/d ≥ 2 the imagery replicates the scene exactly.…”

Point-and-shoot, TV studio broadcast, and thermal infrared imaging cameras have significantly different applications. A parameter that applies to all imaging systems is Fλ/d, where F is the focal ratio, λ is the wavelength, and d is the detector size. Fλ/d uniquely defines the shape of the camera modulation transfer function. When Fλ/d<2, aliased signal corrupts the imagery. Mathematically, the worst case analysis assumes that the scene contains all spatial frequencies with equal amplitudes. This quantifies the potential for aliasing and is called the spurious response. Digital data cannot be seen; it resides in a computer. Cathode ray tubes, flat panel displays, and printers convert the data into an analog format and are called reconstruction filters. The human visual system is an additional reconstruction filter. Different displays and variable viewing distance affect the perceived image quality. Simulated imagery illustrates different Fλ/d ratios, displays, and sampling artifacts. Since the human visual system is primarily sensitive to intensity variations, aliasing (a spatial frequency phenomenon) is not considered bothersome in most situations.

“…Different kinds of camera more or less adapted to UV wavelengths have been developed. When thinned, CCD [ [6]] have the capability to present large quantum efficiency in ultraviolet. Such devices have been developed for space applications and are now largely used in spectroscopy or microscopy.…”
