Title: Detection of focus
Inventor: KATOU KIICHI
IPC: G02B7/28
Filed: 1981-05-01
Abstract: PURPOSE:To improve the sensitivity of detection in the detection of focus utilizing total reflection in accordance with the critical angle by combining a transparent prism having a reflection preventing thin film with a polarizing film. CONSTITUTION:The light from a laser source 11 converged with an objective lens 15 is reflected by a disc 16, and is polarized to S polarized light by a 1/4 wavelength plate. This light is made incident to a polarizing prism 13. The incident light thereof is reflected by the prism 13 and is made incident to a transparent prism 17 having a reflection preventing thin film 20. This incident light is made incident to the prism 17 in such a way that the incident angle is the critical angle or smaller than this at the boundary face between the thin film 20 and air. The change in the quantity of the reflected light from the boundary surface is detected with a photodetector 19, whereby the focus of the lens 15 upon a disc 16 is detected. Since the change in reflectance in accordance with the fluctuations in the incident angle of the S polarized light is made sharp by this, the sensitivity of detection is improved.

Filed: 1990-03-15
Abstract: PURPOSE:To carry out copying repeatedly without destroying a master electric charge image by making a first medium on which the electric charge image is formed by giving electromagnetic information such as an optical image to a photoconductive layer, allowing the first medium forming the charge image to be a master and executing the recording by the imparting an electric field based on the electrical charge image to the recording medium provided with an optical modulation material. CONSTITUTION:When the electromagnetic information such as the optical image of an object O which is the object to be recorded with a lens L, is formed as an image on the photoconductive layer 5, an electron hole pair is generated inside the photoconductive layer 5 according to the brightness or the darkness of that image. Then, aerial discharge is generated between the photoconductive layer 5 and charge holding layer 6 when the voltage of power source Vb is impressed, and the electrical charge image corresponding to the optical image is formed on the surface of the charge holding layer 6. Then the first recording medium 1 with the electrical charge image formed on the charge holding layer 6 is made to be the master, electric field due to the electric charge image is imparted to the optical modulation material layer 7 by facing a recording medium 2 provided with the optical modulation material layer 7 to the recording medium 1 and recording is carried out by allowing the optical modulation material to be reacted. Thus, the high resolution electric charge information recorded to the electrical charge image recording medium 1 can be repeatedly copied to other recording media 2 without destroying it.
