Abstract: A method for the acquisition (AU) of a spectrally resolved, two-dimensional image by means of Fourier transform (=FT) spectroscopy or Fourier transform infrared (=FTIR) spectroscopy, is characterized in that, during multiple passes (D1-D4) of an optical path difference (OG) between two partial rays (14a, 14b) over an identical range (IB), different subsets of detector elements (22) of an array detector (5) are read out and the signals of the read-out detector elements (22) of the multiple passes (D1-D4) are Fourier transformed and combined to form the spectrally resolved image. A method is thereby provided for the acquisition of two-dimensional, spectrally resolved images, in which the influence of vibrations on the measurement is reduced, and which is less affected by the movement of objects to the resolved spectrally.

Abstract: Every depth of the measurement object measures energy structural information, refractive index, transmittance, reflectance other than property information of (as for the resolution several microns), e.g., space information at the same time. A spectrum measurement device receives a reference wave propagating in a reference path and a measurement wave propagating in a measurement path having a start point same as a start point of the reference path, and derives a spectrum of the measurement wave. The space information of the measuring object, energy structural information, refractive index, transmittance, a reflective index using spectrum measurement device are derived.

Abstract: A fundamental limit to the sensitivity of optical interferometry is thermal noise that drives fluctuations in the positions of the surfaces of the interferometer's mirrors, and thereby in the phase of the intracavity field. A scheme for substantially reducing this thermally driven phase noise is provided in which the strain-induced phase shift from a mirror's optical coating cancels that due to the concomitant motion of the substrate's surface. As such, although the position of the physical surface may fluctuate, the optical phase upon reflection can be largely insensitive to this motion.
