1. A monitoring system comprising:
- a sensor capable of being operatively coupled to a medical monitor, the sensor comprising;
a sensor body capable of being applied to a patient'"'"'s tissue;
an adaptive light emitting structure disposed on the sensor body and configured to emit light at a first wavelength, wherein the adaptive light emitting structure comprises a plurality of configurable elements configured to be independently addressed to change a path of the emitted light from at least one of the configurable elements relative to at least one other configurable element of the plurality of configurable elements and to change an intensity profile of light at the first wavelength emitted by the adaptive light emitting structure; and
a detector disposed on the sensor body and spaced apart from the adaptive light emitting structure, wherein the detector is capable of detecting at least a portion of the emitted light; and
a medical monitor comprising a processor, wherein the processor is configured to independently address the configurable elements of the adaptive light emitting element to change the path and the intensity profile of the emitted light.

Abstract
According to embodiments, sensors and systems for medical spectroscopy may include adaptive optical components, such as digital light processing components. Adaptive light emitting elements may allow such sensors to alter the intensity profile of emitted light photons to change the distribution of photons through the tissue or to scan areas of tissue to determine if certain areas may be associated with improved measurements. In addition, sensors with adaptive light detecting elements as provided may adapt to selectively detect light of certain wavelengths or from certain regions of the tissue.
