<p>An optical instrument assembly for scanning biochips for DNA samples includes a transmitter for projecting an optical signal having at least a first and a second spectral array onto a DNA containing specimen. A detector includes a sensor for detecting an emitted optical signal from the specimen. A first drive mechanism varies the position of the optical signal on the specimen in a forward and a reverse direction. A second drive mechanism varies the position of the specimen relative to the optical signal. A controller terminates detection of one of the spectral arrays while varying the position of the optical signal in the forward direction and terminates detection of the other spectral array while varying the position of the optical signal in the reverse direction.</p> |
