Title: Photoelectric surface
Inventor: SUZUKI SHINJI
IPC: H01J1/34
Filed: 1991-03-04
Abstract: PURPOSE:To improve sensitivity in the ultraviolet range and to reduce in relative sensitivity in the visible light range by sequentially laminating a base film made of a conductive material, an intermediate layer containing alkali metal and halogen and a photoelectric conversion film containing tellurium and alkali metal on a base. CONSTITUTION:When a CsCl intermediate layer 3 is used between a Cs-Te photoelectric conversion film 4 and a base layer 2, a suitable quantity of CsCl is added to a previously cleaned Pt-Mo film. It is set in a bulb having a glass base 1 previously formed with a Cr thin film in vacuum, The CsCl of a suitable quantity is deposited on the base 1. When the bulb is sufficiently heated, alkali metal (Cs) is introduced into the bulb, and the photoelectric surface is irradiated with an ultraviolet light to monitor a photocurrent. The sensitivity is raised by using an alkali salt layer of the CsCl, etc., between the film 4 and the base metal film. The sensitivity in the unnecessary visible light range is suppressed to a low value, and an ultraviolet photoelectric surface having excellent solar blind characteristic is obtained with very high sensitivity.

Filed: 1982-03-11
Abstract: PURPOSE:To obtain an optical modulator which realizes the direction changing operation of light expensively with a small size by mounting transducers respectively on the opposed surfaces of an acoustooptic medium, and setting the angles of the opposed surfaces at a specific angle with respect to the incident direction of light. CONSTITUTION:Transducers (piezoelectric elements) 6, 6' are adhered to the opposed surfaces of an acoustooptic medium 5. The angles alpha, beta assumed by the opposed faces and incident angles are set at alpha=lambdaf1/2v, beta=lambdaf2/2v. Here, lambda is the wavelength of incident light, and (v) is the propagation speed of acoustic waves in the medium 5. When only the signal of a frequency f1 is applied to the transducer 6, only the light 7'' diffracted in the direction 2alpha exists in addition to transmitted light 7' in the exit light. Similarly, when only the signal of a frequency f2 is applied to the transducer 6', the transmitted light 7' and the diffracted light 7''' exist. Thus, the changeover of the incident light 7 to the directions of the diffracted light 7'', 7''' is accomplished easily.
