摘要： A spectrometer includes an illuminating section; a receiving section configured to detect radiation reflected from an object including an optically inhomogeneous scattering medium; a hardware section configured to obtain a solution of an inverse problem to reconstruct an absorption spectrum of the optically inhomogeneous scattering medium, wherein the illuminating section includes at least one light-emitting diode source, a radiation spectral curve of which is divided, by at least two spectral filters having different spectral transmission curves, into at least two spectral regions, to form an equivalent radiation spectrum from at least two spectral sources, and wherein the hardware section applies the solution of the inverse problem based on information about a spectral content of the radiation of the illuminating section, a signal obtained in a form of a response from the optically inhomogeneous scattering medium, and a spectral sensitivity curve of the receiving section.

摘要： An optical device includes a light input part and a light output part. The light input part includes a micro display; a first and a second polarizing beam splitters configured to reflect or transmit incident light including an image displayed on the micro display; and a first quarter wavelength plate configured to receive light transmitted by the first polarizing beam splitter or the second polarizing beam splitter and change a polarized state of the received light. The light output part includes a third and a fourth polarizing beam splitters configured to transmit or reflect light including the image received from the light input part; a second quarter wavelength plate configured to receive the light transmitted by the third polarizing beam splitter or the fourth polarizing beam splitter and change the polarized state of the received light, and a light condenser configured to condense the polarized light.
