Disclosed is a volume sensor having first, second, and third laser sources emitting first, second, and third laser beams; first, second, and third beam splitters splitting the first, second, and third laser beams into first, second, and third beam pairs; first, second, and third optical assemblies expanding the first, second, and third beam pairs into first, second, and third pairs of parallel beam sheets; fourth, fifth, and sixth optical assemblies focusing the first, second, and third beam sheet pairs into fourth, fifth, and sixth beam pairs; and first, second, and third detector pairs receiving the fourth, fifth, and sixth beam pairs and converting a change in intensity of at least one of the beam pairs resulting from an object passing through at least one of the first, second, and third parallel beam sheets into at least one electrical signal proportional to a three-dimensional representation of the object. 1. A non-contact volume sensor , comprising:first, second, and third laser sources configured to emit first, second, and third laser beams;first, second, and third beam splitters configured to split the first, second, and third laser beams into first, second, and third beam pairs;first, second, and third optical assemblies configured to expand the first, second, and third beam pairs into first, second, and third pairs of parallel beam sheets;fourth, fifth, and sixth optical assemblies configured to focus the first, second, and third parallel beam sheet pairs into fourth, fifth, and sixth beam pairs; andfirst, second, and third detector pairs configured to receive the fourth, fifth, and sixth beam pairs and convert a change in intensity of at least one of the fourth, fifth, and sixth beam pairs resulting from an object passing through at least one of the first, second, and third parallel beam sheets into at least one electrical signal proportional to a three-dimensional representation of the object.2. The non-contact volume sensor of claim 1 , wherein the ...
