    Abstract: 1301143 Deflecting light RCA CORPORATION 6 Feb 1970 [13 Feb 1969] 5763/70 Heading H4F A laser beam 21 passing through a transparent medium 20 such as water, KTN or quartz is intercepted at the Bragg angle # by acoustic wavefronts selectively produced from either of two convergently disposed transducers 22, 32 controlled by switch 40 and is thereby diffracted by 2# in either of two senses, 24, 34. A cascade of such deflectors may be used for X and Y deflection. Successive deflections in one direction may be obtained from similar elements using parallel mirror pairs to space the beams after each deflection, Fig. 3 (not shown), or alternatively, Fig. 4 (not shown), diminishing degrees of deflation are provided by each successive element, charging the acoustic frequency and Bragg angle as necessary. The transducers may be separate electrical units, e.g. of cadmium sulphide, or if the medium 20 is suitable it may itself form a transducer, e.g. a lithium niobate crystal provided with electrostatic electrods.

    Abstract: A comb filter comprising a charge transfer device (CTD) structure for separating frequency interleaved luminance and chrominance components of a composite color television signal directly within the CTD structure. The CTD structure has first and second pairs of input sections of substantially identical geometry, one input section of the second pair being preceded by a signal inverter. Signal charge as applied to the first and second input pairs are delayed such that signal charge from the first input pair exhibits a 1H delay relative to signal charge from the second input pair, when the signal charge from the respective input pairs are combined with each other. A first charge summing well combines mutually in-phase signal charge at multiples of the line scanning frequency from the first and second inputs to provide a combed luminance signal charge component, while a second well combines mutually inverted or out-of-phase signal charge at these frequencies from the first and second inputs to provide a combed chrominance signal charge component.
