Patent EP-0942297-A2 (EP)
Inventor: SAKUMA SHIGERU
IPC: G02B5/30
Filed: 1999-03-11
Abstract: The present invention provides a method for calculating the birefringence of an optical
element and selecting the direction of minimum birefringence in the optical element. A material
for manufacturing the optical element is a fluoride single crystal with a birefringence value that
is reduced compared to conventional materials. The fluoride single crystal is cut from a fluoride
single crystal ingot obtained by crystal growth so that the {111} crystal planes are two parallel
planes, after which the optical performance is improved by subjecting this material to a heat
treatment. The birefringence of the optical element is calculated by converting known piezo-optical
constants in a specified three-dimensional orthogonal coordinate system for the optical
material into piezo-optical constants in an arbitrary three-dimensional orthogonal coordinate
system. The amount of change in the refractive index Δn1 of the optical material in a first
direction along the direction of one coordinate axis of the arbitrary three-dimensional orthogonal
coordinate system, and the amount of change in the refractive index Δn2 of the optical material
in a second direction which is perpendicular to the first direction are calculated using a uniaxial
stress that is applied to the optical material along the first direction and the piezo-optical
constants in the arbitrary three-dimensional coordinate system. The amount of birefringence as
seen from a third direction perpendicular to the first direction and the second direction is
determined in the arbitrary three-dimensional orthogonal coordinate system by determining the
difference between the amount of change in the refractive index Δn1 and the amount of change
in the refractive index Δn2.

Abstract: The method involves clocking a first mains power converter (13), to supply a first intermediate circuit (17), and clocking a drive power converter (19) to supply power from the first intermediate circuit to a first drive unit (1) to produce a first partial moment (M). A second mains power converter is clocked to feed a second intermediate circuit. A second drive power converter is clocked to supply power from the second intermediate circuit to a second drive unit to produce a second partial moment.  The first partial moment is reduced to zero and the second partial moment is raised to the sum of the two partial moments. After the first partial moment is reduced to zero, the first mains power converter is blocked and the first intermediate circuit is reduced from an operating voltage to a standby voltage.

Abstract: A technique (200) for compressing video images (102) uses temporary compression of blocks during compression, integrated color rotation of compressed images, direct compression of a composite video signal, and border filters to allow blocks to be compressed independently. Temporary compression reduces storage needed in an integrated circuit. An incoming frame (12) is compressed block-by-block and placed in temporary storage (118). A corresponding block of a later frame is also compressed. Both blocks are decoded back into the transform domain and the two blocks are compared in the transform domain (122). Color rotation (132) on compressed color information is integrated with overall compression and is performed upon the chrominance transform pyramids (592, 596) after transformation of the video signal rather than performing a rotation on the raw signal itself. Color rotation (132) is performed at any stage and uses serial multiplication (shift and add) for more efficient processing, rather than using parallel multiplication. A composite video signal (82) including both color and black and white information is compressed directly without separating the color information from the black and white. A sequence of passes (214, 224, Figs. 12-16) separates the luminance and chrominance information from the composite video signal and demodulates the color carrier to separate out color information. Blocks of information are treated independently using a modified 2-6 Biorthogonal filter (106a, 409) to reduce complexity, to reduce harware needed and to reduce blocking artifacts. The technique identifies and compresses composite video, S video, and component video signals, and is applicable to low bit rate video applications.
