The "scanner" of the title is a holographic recorder/projector on which the main character views clips of his own life but doesn't recognize them. It is also a reference to a Biblical verse in I Corinthians 13 that includes "we see as through a mirror darkly", and thus refers to the main character's weak grasp on reality. SD, the initials of Scanner Darkly, are presumably clipped from LSD, and are also the initials of Substance D, the drug that is one of the stars of the book.

The autobiographical nature of the novel is explained in the moving afterword, where Dick dedicates the book to those of his friends -- he includes himself -- who suffered debilitation and/or death as a result of their drug use. This is mirrored in the involuntary goodbyes that occur throughout the story.
Dick was himself a participant in a Synanon-type recovery program at one point, as is portrayed in his 1988 novel The Dark-Haired Girl. Presumably this is a source of the vividness and accuracy with which the clinic is portrayed.
