Abstract: The invention refers to an optical instrument for determining a wavelength of light generated by a light source, comprising a signal generator for generating a modulation signal, a tunable optical filter device configured to receive the modulation signal, the tunable optical filter device configured to modulate the light generated by the light source based on the modulation signal, an optical detector device configured to detect a degree of modulation of light modulated by the tunable optical filter device, and an analyser configured to determine the wavelength of the light based the degree of modulation.

Abstract: An optical instrument for determining a wavelength of light generated by a light source. The optical instrument may include a signal generator for generating a driving signal, a tunable optical filter device configured to receive the driving signal, the tunable optical filter device configured to diffract the light generated by the light source based on the driving signal, an optical detector device configured to detect a timing of maximum diffraction of light diffracted by the tunable optical filter device, and an analyzer configured to determine the wavelength of the light based the timing of maximum diffraction.
