Paper Abstract

One factor which affects the ability to image an underwater object from the atmosphere is water turbidity. The performance of an imaging system is often expressed by the limiting resolution which is determined from the contrast transfer function (CTF). The image quality is usually expressed in terms of the modulation transfer function (MTF). This paper presents the results from carefully controlled laboratory experiments to determine the CTF's and the MTF's of a turbid water medium for Jackson turbidity units (JTU's) ranging from 0 to 24. MTF's are generated from a narrow strip target and CTF's are generated from standard resolution bar targets. MTF results are compared with earlier work and CTF's calculated from MTF's are compared with measured CTF's.
