Abstract
ABSTRACT:Over the last 100 years, the methods for traditional visualization of latent ifngerprints have been improved, and meanwhile, many new techniques and approaches have been applied in this area. In general, the latest technology mainly includes new material, electrochemiluminescence imaging, biotechnology, spectral imaging, mass spectrometry, etc. The novel visualization technology overcomes the limitation of the traditional ones in many aspects of visualization sensitivity and efifciency, especially wins a lot of applauses when dealing with the old latent ifngerprints at trace level, marking the beginning of a new era of latent ifngerprint visualization. However, the new technology over-relies on some expensive equipment and reagents, and requires high demanding practices. As a result, a great deal of work has to be done further, to make sure that it can completely replace the traditional methods in more practical term in the foreseeable future. This paper reviews the research progress in the application of new technology, and looks forward to the future development of latent ifngerprint visualization technology.关键词
