The data necessary for a successful design are spectral characteristics of light sources, detectors and a variety of optics to be used in the final assemblage, dispersion characteristics of the materials used in the wavelength range of interest, and a set of calibrated sample spectra for pattern-recognition-based analysis.

Near-infrared spectral measurements of this object carried out by S . J . Bus ( University of Hawaii ) using the NASA IRTF telescope on Mauna Kea, Hawaii, indicate that its spectral characteristics do not match those of any of the known asteroid types, and in fact are similar to those of a rocket body.

:The tone, timbre, other spectral characteristics, and envelope characteristics like ringing involve complex interactions between a substance's density, tensile strength, hardness, compressibility, elastic modulus, surface texture ( especially if it's involved in a highly inelastic collision ), acoustic and mechanical dampening characteristics, size, and shape, as well as the force and composition of the material striking it.

Noteworthy results of the study of the spectral characteristics of the double-barrier structure with a corrugated surface of the photodetector as well as sensitive to the impurity region of the spectrum ( A . V . Karimov, Yodgorova D . M ., Giyasova F . A ., Azimov T . M ., U . M . Buzrukov, Yakubov A . A . ).
