Claim One:
1. A method of non-contact volume measurement of an object, the method comprising the steps of: emitting a plurality of light beams from three light sources on three axes; acquiring data on a plurality of light intensities received from the plurality of light beams; identifying a change in intensity in at least one of the plurality of received light beams; determining a presence of the object when the change in light intensity exceeds a predetermined magnitude in a predetermined number of received light beams; determining an end of the presence of the object when the change in light intensity falls below the predetermined magnitude in the predetermined number of received light sources; splitting the plurality of light beams into a plurality of beam pairs; expanding the plurality of beam pairs into a plurality of beam sheet pairs; directing the plurality of beam sheet pairs across an object aperture so that the object casts shadows on a collecting lens as the object passes through the plurality of beam sheet pairs; and focusing each of the plurality of beam sheet pairs into focused beam pairs.
