11. detection methods as claimed in claim 10, is characterized in that, the described process determining that folded light beam position is determined according to the light receiving unit position receiving folded light beam is;
The described recording materials surplus value of information determined in recording materials storehouse adopts formula 100 × (n-m)/(n-1) % to calculate, wherein, n is the total number of light receiving unit, m be receive folded light beam light receiving unit numbering, light receiving unit from 1 to n along with the sequencing that can receive folded light beam is arranged in order.
