Title:
OPTICAL SENSOR DEVICE, METHOD FOR ADJUSTING A SPECTRAL RESOLUTION OF AN OPTICAL SENSOR DEVICE AND SPECTRAL MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/059827
Kind Code:
A3
Abstract:
The invention relates to an optical sensor device comprising a linear variable filter (10) with a predetermined axis (12) along which a passband wavelength of the linear variable filter (10) linearly varies within a range of values limited by a minimum passband wavelength and a maximum passband wavelength, and a detection device (18) having a detection surface (20) on which an array of sensor pixels (22) is configured in such a way that each of the sensor pixels (22) can output or tap a sensor signal (24) with respect to a light intensity which is incident on the respective sensor pixel (24), said detection device (18) being arranged with respect to the linear variable filter (10) such that light beams transmitted through the linear variable filter (10) are incident on the detection surface (20). The invention also relates to a method for adjusting a spectral resolution of an optical sensor device. The invention further relates to a spectral measurement method.
