Abstract

Et reflekterende/diffrakterende lysventilsystem samler lys fra flere dimensjoner rundt en eneste lyskilde. Fra disse mange samledimensjoner dirige- res lyset slik at det treffer ventilen fra et stort antall retninger. Når ven- tilen er utformet for å være reflek- terende, returnerer lyset til kilden. Når ventilen på den annen side er utfor- met for å være diftrakterende eller oppspaltende, overføres lys fra en før- ste og tredje ordens diffraksjon fra ventilen for hver av samledimensjonene, hvilket i stor grad forøker systemets effektivitet.
