22 Ultraviolet recording

22.1 Introduction

A range of subjects and applications require to be imaged or recorded by means of ultraviolet (UV) radiation used in either reflected or fluorescence modes. Applications from life sciences include research into insect vision and flower markings (Figure 22.1). Biomedical recording includes uses in dermatology, ophthalmology and fluorescence angiography. Conservation work and art restoration rely heavily on UV imagery. Forensic applications include fingerprints, old lesions on skin, body fluid detection by DNA fluorescence, and the inspection of suspect documents. Non-destructive testing methods include crack detection by UV fluorescent penetrating agents. Security systems use fluorescent markings on stamps, ...
