88 Optical switch US680317 1976-04-26 US4023498A 1977-05-17 Paul Harris
An optical switch, which may be a part of a fuze for an explosive project, comprises a housing made up of a hollow cylindrical part with two end plates welded thereto and having a pair of aligned glass windows sealed through opposite sides for transmitting light transversely therethrough, a gas piston with O-ring seals slidable in the housing to define an end wall of a variable volume gas chamber therein and adapted to be moved by inertia during projectile launch to decrease the volume of the chamber and thereby increase the gas pressure, means for locking the piston in the new position, a valve in the housing for admitting a light attenuating gas to the chamber, an adjustable pressure relief valve in the housing adapted to open when the internal gas pressure exceeds the external pressure by a given amount, a light source positioned adjacent to the outside of one of the windows to project light through the windows and the attenuating gas, and a light-sensitive device positioned on the other side of the housing to receive the attenuated light. When the intensity of the light received by the device equals a critical value, the device responds by performing a desired function, such as arming a firing circuit of the fuze. The gas pressures in the chamber before and after piston movement are higher than a critical pressure at which the light reaching the output device has the critical value. When the projectile is projected to a desired altitude, the reduced atmospheric pressure causes the relief valve to open, reducing the chamber pressure below the critical pressure, thereby exciting the light sensitive device to arm the fuze.The switch may be used with a gas chamber of fixed volume, with a higher initial gas pressure.
89 Passive infra-red proximity fuze US587568 1975-06-17 US4022132A 1977-05-10 Ake Hugo Petrus Blomqvist; Bertil Torbjorn Eriksson
Apparatus for use in a projectile-borne passive infra-red proximity fuse for detecting infra-red radiation emitted from a target. The apparatus includes at least one pair of optical means which are respectively located at spaced locations around the periphery of the projectile. The pair of optical means is so located that the beams of infra-red radiation associated therewith, which are both imaged upon a common detector, form an angle therebetween both in a plane through the longitudinal axis of the projectile and in a plane normal to such axis. Logic circuitry is provided and controlled by the detector to provide a distinctive output in response to the signals which are generated by the beams of radiation received from a target which is spinning about its longitudinal axis and is within a predetermined distance of the projectile. With the arrangement as described, the detection apparatus produces either two separate pulses or one long pulse for each revolution of the projectile about its longitudinal axis, whereas only a single pulse is produced for each revolution from distant sources of infra-red radiation such as the sun.

91 Optical fuze and/or miss distance indicator US503998 1974-09-06 US3942446A 1976-03-09 Orval R. Cruzan
An optical miss distance detector and/or fuzing device for a missle. Four tical ring sensors are disposed around the missile body and the active sensing regions of the first and second sensors are disposed at an angle of 90.degree. to the missile axis thereby forming first and second cones of 90.degree. with respect to the axis while the active sensing regions of the third and fourth sensors are disposed at an angle of other than 90.degree. to the axis thereby forming cones of other than 90.degree. with respect to the axis. The third and fourth sensors are positioned along the axis so that the apices of the third and fourth cones coincide respectively with the apices of the first and second cones. The miss distance and relative velocity of the missile and the target are determined based on the times of interception of the cones and the azimuthal angles of interception. A fuzing arrangement is connected to the sensors which generates a detonation signal responsive to a predetermined order of interception of the cones indicating that the target is crossing the missile within a predetermined range.
