Abstract

Since a hologram can simultaneously scan and focus a laser beam, we have investigated the use of a holographic line scanner in laser printers. However, conventional holographic scanners, suffer from wavelength shifts of laser diodes. To prevent problems caused by wavelength shifts, a conventional holographic scanner needs an expensive thermal controller for a laser diode or a frequency-stabilized laser diode. To achieve a low cost scanner, we proposed a new holographic scanner using a holoplate that compensates for large wavelength shifts. In this paper, we will discuss the wavelength shift compensation of a new scanner.
