1. A sensing system comprising:
a measurement sensor of a plurality of measurement sensors configured to detect electromagnetic radiation;
a reference sensor of a plurality of reference sensors configured to detect a source of measurement uncertainty, wherein the plurality of measurement sensors and the plurality reference sensors are arranged to form an array, wherein the array comprises alternating measurement sensors and reference sensors; and
a shield housing having two or more walls configured to reduce an interaction between the electromagnetic radiation and the reference sensor, wherein the shield housing surrounds at least two sides of the reference sensor, wherein the measurement sensor and the reference sensor are located on a single integrated circuit, and wherein the shield housing comprises the two or more walls located in a trench within the integrated circuit,
wherein a number of the measurement sensors is equal to a number of the reference sensors multiplied by an integer greater than one, and wherein the measurement sensors are configured to collect data for a first amount of time per measurement and wherein the reference sensors are configured to collect data for a second amount of time per measurement, wherein the second amount of time is equal to the first amount of time multiplied by the integer.
