We report what are to our knowledge the first coherent images recovered in the laboratory from measurements made with a Shack–Hartmann wave-front sensor of the phase and amplitude of a laser speckle wave front. We discuss the design of our wave-fro

In this paper, we present an application of microlens-based Hartmann wavefront sensors. The wavefront sensors, which employ arrays of one-dimensional cylindrical microlenses, are used in a multiview optical tomography system to provide a nonintrusive

The presence of clouds of ice particles in the uplink and downlink path of an illumination beam can severely impede the performance of an active imaging system. Depending on the optical depth of the cloud, i.e., its density and depth, the beam can be

SummaryPsittacosis - lymphogranulomatrachoma agents were isolated from conjunctival scrapings from 9 of 17 sheep representing 3 different flocks afflicted to 90% with follicular conjunctivitis. The PLT agent isolated from follicular conjuctivitis was

A feedlot enterprise fattened 50,000 lambs from August, 1973, through May, 1974. Of those that died during that period, 96 were necropsied; of this number 27 (28%) were infected with cysticeri. The parasites produced bore channels in livers and bladd

Of 133 feedlot lambs that died and were necropsied, 67 had normal lungs and 66 had pneumonic lungs. The middle ears of all lambs were opened by a specified technique. Of the 67, 8 (12%) had otitis media, and of the 66, 26 (39%) had otitis media. The

During all of 1974 we surveyed, for illnesses and deaths, about 407,000 yearling feedlot cattle. The morbidity was 5.1%, with a case mortality of 18.9% and a population mortality of 1.0%. Both morbidity and mortality were higher during fall and winte

From a Colorado enterprise annually fattening about 50,000 lambs, 3,664 animals were examined for muscular cysticercosis. Of the total number, 406 (11.1%) were parasitized, wheras an estimated 0.1% of Colorado lamb carcasses are infected. Of the infe

Throughout all of 1974, we surveyed, for illnesses and deaths, about 407,000 yearling feedlot cattle. Of 1,988 cattle necropsied, 25 (1.3%) had ruptured pulmonary aneurysms and an additional 4 had gross pulmonary emboli without rupture. The emboli or
