Bath interferometers can be used to test telescope mirrors of any size. A Common path interferometer has the test and reference beams traveling over effectively the same path which has the advantage that you can use an inexpensive semiconducting laser pointer with low coherence versus other interferometers which need a high coherence laser ...
Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye.
Bath, Patricia: 1942–2019 Ophthalmologist: First African-American female physician to receive a patent for a medical invention; inventions relate to cataract surgery and include the Laserphaco Probe, which revolutionized the industry in the 1980s, and an ultrasound technique for treatment [19] [20] [21] Beard, Andrew: 1849–1921
The following is a list of notable African-American women who have made contributions to the fields of science, technology, engineering, and mathematics.. An excerpt from a 1998 issue of Black Issues in Higher Education by Juliane Malveaux reads: "There are other reasons to be concerned about the paucity of African American women in science, especially as scientific occupations are among the ...
(2) The common-path design uses fewer optical components than double path designs, making alignment much easier, as well as reducing cost, size, and weight, especially for large setups. [ 13 ] (3) While the accuracy of a double path design is dependent on the precision with which the reference element is figured, careful design enables the ...
Cataract surgery is one of the most cost-effective health interventions, since its economic benefits considerably exceed the cost of treatment. [ 128 ] [ 129 ] The 1998 World Health Report estimated 19.34 million people were bilaterally blind due to age-related cataracts, and that cataracts were responsible for 43% of all cases of blindness.
"Paveway II" refers specifically to the guidance kit, rather than to the weapon itself. In 2017, Lockheed Martin secured a $22m contract from the US Air Force to deliver tail kits and laser guidance kits for the GBU-12 configured LGBs, in December 2017. Deliveries are expected to commence in the final quarter of 2019. [5]
