Abstract:
1. A method of signal adjustment in an optical sensing device, the optical sensing device including a first optical sensor and a first reference optical sensor, the first optical sensor correlating to a first specified ideal spectral response and generating a first output signal corresponding to light detected thereby, the first reference optical sensor generating a first reference signal corresponding to light detected thereby and being disposed adjacent to the first optical sensor such that the light detected by the first reference optical sensor is substantially the light detected by the first optical sensor, said method to be implemented using a processing unit and comprising the steps of: a) configuring the processing unit to receive the first output signal from the first optical sensor and the first reference signal from the first reference optical sensor; and b) configuring the processing unit to generate a first adjusted output signal having a spectral response that approximates the first specified ideal spectral response, by adjusting the first output signal according to the first reference signal; wherein step b) includes
