OPTICAL SENSING SYSTEM INCLUDING ELECTRONICALLY SWITCHED OPTICAL MAGNIFICATION

摘要

Disclosed is an exemplary optical sensing system including at least one light source for emitting light in a first wavelength range and light in a second wavelength. An image sensor is provided for detecting light emitted from the at least one light source. The optical sensing system also includes a first optical filter disposed in a first optical path extending between the light source and the image sensor, the first optical filter configured to pass light emitted in the first wavelength range, and to substantially block light emitted in the second wavelength range. A second optical filter is disposed in a second optical path extending between the light source and the image sensor, the second optical filter configured to pass light emitted from the at least one light source in the second wavelength range, and to substantially block light emitted in the first wavelength range.
