Abstract
Systems and methods for detecting multiple physical features is described herein. The method may include receiving a sensor signal from a single optical sensor proximate to a measurement region, determining a plurality of sensor responses from the sensor signal, and generating a plurality of measurement signals from the plurality of sensor responses. Each of the measurement signals may correspond to a different respective physical signal of the measurement region.

A method for multi-dimensional sensing, the method comprising:
- receiving a sensor signal from a single optical sensor proximate to a measurement region;
- determining a plurality of sensor responses from the sensor signal;
- and
- generating a plurality of measurement signals from the plurality of sensor responses, wherein each of the measurement signals corresponds to a different respective physical signal of the measurement region.
A system for multi-dimensional sensing of a measurement region, the system comprising:
- an optical sensor;
- a signal processor configured to:
- receive a sensor signal from the optical sensor;
- determine a plurality of sensor responses from the sensor signal;
- and
- generate a plurality of measurement signals from the plurality of sensor responses, wherein each measurement signal corresponds to a different respective physical signal of the measurement region.
