What is a Laser Digitizer?
Definition: A laser scanner that employs a laser to capture image information to digital form. Very high resolution and wide gray scale range are possible.
Because it uses coherent light, the laser scanner can penetrate thick films (an ability measured in units of optical density) and extract information better than CCD scanners.
Serves the same function as CCD X-ray scanners, but generally at higher resolution, better contrast, and much higher price.
