A SENSING SYSTEM AND METHOD THEREOF

摘要

The present invention is a sensing system and method with substantially reduced or zero light effect. The arrangement of the system of the present invention comprises at least two sensors (10,20); whereby at least one sensor (20) is configured to detect light and one sensor (10) is configured for measuring samples; an analog read-out circuitry connected to at least one sensor (10), at least one adaptive gain control means (40) connected to the light sensor (20) for optimizing the output from the light sensor (20); and a differential amplifier (50); wherein the adaptive gain control means (40) is configured to optimize the output from both sensors (10, 20) for light compensation, by way of equalizing the light coefficient factor (ß, a) by both sensors (10,20).
