Abstract

Devices and methods for measurement of energy from a defined source having increased accuracy in measuring low energies. The device comprises a housing containing sensors. A first sensor receives energy from the source and produces a first output. A second sensor receives ambient energy only and produces a second output. Subtraction of the second output from the first output produces a more accurate corrected output. The method includes providing a housing containing a first sensor and a second sensor and directing energy from the defined source to a surface of the first sensor thereby causing the first sensor to produce a first output while only ambient energy from sources other than the defined source is applied to a surface of the second sensor which produce a second output that is subtracted from the first output producing a corrected output.
