DEFINITION

Classification: 347/225

Scan of light:

(under subclass 224) Subject matter wherein at least one writing beam (e.g., light, electrons) whose energy varies in magnitude, or duration, or frequency in accordance with the electrical information signal, is progressed point by point or line by line (e.g., LEDs) across the record receiver to produce scan lines constituting a record of the signal.
