| 6485981 | Method and apparatus for imaging and documenting fingerprints The invention relates to a method and apparatus for imaging and documenting fingerprints. A fluorescent dye brought in intimate proximity with the lipid residues of a latent fingerprint is caused to fluoresce on exposure to light energy. The resulting flu... | 11/26/2002 |
| 5818582 | Apparatus and method for phase fluorometry A phase fluorometer employs a baseband frequency generator to generate a sample baseband signal at a first frequency fo and a reference signal correlated to the sample baseband signal. A second signal generator generates a carrier signal having... | 10/06/1998 |
| 4923819 | Time-resolved fluorescence immunoassay Fluorescence immunoassay for determining single or multiple analytes based upon a single measurement of fluorescence are described.... | 05/08/1990 |
| 4855930 | Method and appartatus for improved time-resolved fluorescence spectroscopy A method and apparatus for time-resolved fluorescence spectroscopy is described in which laser light from a single pulse is used to excite fluorescent photons in a sample, which fluorescence is detected by a PMT optimized for linearity and response time t... | 08/08/1989 |
