Abstract: A biometric measurement device including a photodiode array having a number of photodiodes and at least one polarization filter covering at least one of the photodiodes. The biometric measurement device also includes a light-emitting diode array having a number of light-emitting diodes proximate to the photodiode array, a non-volatile memory device, and a processor in electronic communication with the non-volatile memory device. The photodiode array is configured to receive a reflected waveform from light emitted from the light-emitting diode array, and the processor is configured to determine at least one physiological parameter based on a pulsatile (AC) component and a static (DC) component of the reflected waveform. The light-emitting diodes may emit polarized light.
