Claim 7:
8. The optical device of claim 1, wherein the detector (40) is an assembly of lenses and image sensors, or an eye of a human, or said detector (40) is selected from a charge-coupled device (CCD) imager, an electron-multiplying charge-coupled device (EMCCD) imager, an avalanche photodiode (APD), a complementary metal-oxide-semiconductor (CMOS), and a scientific-complementary metal-oxide-semiconductor (sCMOS) imager, or said detector (40) is selected from a monochrome detector designed to read intensity changes in the optical spectrum of the spatially intensity-modulated reading light beam (m), a colour detector designed to read colour changes of the spatially intensity-modulated reading light beam (m), a spectral camera designed to read wavelength shifts of the spatially intensity-modulated reading light beam (m), a spectrometer, a colour mask and a tunable filter.
