RT Journal Article ID 37f00a4f69491259 A1 Talley, Douglas A1 Hassani, M. T1 ACCOUNTING FOR DEPTH OF FIELD IN SIZING SPHERICAL PARTICLES BY IMAGING JF Atomization and Sprays JO AAS YR 1992 FD 1992-12-01 VO 2 IS 4 SP 385 OP 409 AB A general approach to correcting for depth-of-field effects in sizing spherical particles by imaging is presented, and shown to reduce to two other well-known but heretofore apparently unrelated methods as special cases. The approach is adaptable to a wide variety of conditions by means of functions that are measured during calibration. Most generally, correcting for depth-of-field effects requires traversing the object plane through the particle field. However, conditions are identified that allow proper corrections to be made without having to move the object plane. The dynamic range of an instrument as a function of distance from the object plane, or the dynamic envelope, measured during calibration will not necessarily be the same as the one actually realized in measurement, which can be significantly different. This must be taken into account as part of the measurement process. PB Begell House LK https://www.dl.begellhouse.com/journals/6a7c7e10642258cc,28940dbe207f2c99,37f00a4f69491259.html
