초록 ▼

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.

대표청구항 ▼

An optical sensing system comprising: a first light source configured to emit light in a first wavelength range;a second light source configured to emit light in a second wavelength range;a single image sensor configured for detecting light emitted from the first and second light sources;a first pressure chamber with a first flexible diaphragm, the first flexible diaphragm having a first visually accessible surface;a second pressure chamber with a second flexible diaphragm, the second flexible diaphragm having a second visually accessible surface;a first optical filter disposed in a first optical path and a second optical path, the first optical path and second optical path extending between the first light source and the image sensor, the first optical filter configured to pass at least a portion of the light emitted from the first light source in the first wavelength range, and to substantially block the light emitted from the second light source in the second wavelength range, the first optical path including the first visually accessible surface, and the second optical path including the second visually accessible surface;a second optical filter disposed in a third optical path extending between the second light source and the image sensor, the second optical filter configured to pass at least a portion of the light emitted from the second light source in the second wavelength range, and to substantially block the light emitted from the first light source in the first wavelength range, the third optical path including the first visually accessible surface;a first optical magnifying optical element disposed in the first optical path;a second optical magnifying element disposed in the second optical path;wherein an optical magnification of the first optical magnifying element is different than an optical magnification of the second optical magnifying element. 9. The system of claim 8 further comprising: a plurality of reflecting elements disposed in the first and second optical paths. 10. An optical pressure sensing system comprising: a pressure chamber at least partially bounded by a flexible diaphragm;a first light source that emits light in a first wavelength range;a second light source that emits light in a second wavelength range;a first optical filter that passes light in the first wavelength range and blocks light in the second wavelength range;a second optical filter that passes light in the second wavelength range and blocks light in the first wavelength range;a first optical magnifying element;a second optical magnifying element; andan image sensor that detects light emitted from the first and second light sources;wherein light emitted from the first light source reflects off of the flexible membrane, passes through the first optical filter and the first magnifying element and reaches the image sensor; and light emitted from the second light source reflects off of the flexible membrane, passes through the second optical filter and the second magnifying element and reaches the image sensor. 11. The system of claim 10 wherein the first magnifying element has a different optical magnification than the second optical magnifying element. 12. The system of claim 10 further comprising: an optical reflecting element that reflects light from the first light source.
