摘要： Provided is a selectively filtered vision protection system for defense against aircraft laser threats. The system comprises a viewing device having a frame supporting a transparent viewing surface. The frame is configured to be positioned on the face of a user such that the user may see through the viewing surface. A selective filter is positioned adjacent to the viewing surface such that the angle of the field of view of the user is regulated in at least one orthogonal plane. The viewing angle is selected to prevent light transmitted from a light source, located outside of the viewing angle, from being viewed by the user. The selective filter is configured to operate in a first mode for transmitting light unrestricted through the viewing surface, and a second mode to regulate the angle of the field of view of the user in at least one orthogonal plane.

摘要： A facsimile document scanner 10 is illustrated which includes an optical system 23 having a folded optical path 40 and an adjustable lens system 42. A test pattern 60 in the form of a plurality of alternate light and dark stripes 64, 66 is focused upon a linear photodiode array 50 mounted in an integratd circuit pack 51. The number of light and dark stripes 64, 66 is equal to the number of photodiodes in the linear photodiode array 50 across the document width. For adjustment purposes, an oscilloscope 70 is connected to a serial output from the integrated circuit pack 50 and the position of the lens system along the optical path 42 is adjusted and a corresponding adjustment is made to the pointer of the lens holder 45 within the lens housing 43 to obtain the desired image size and focus. The position of the diode array 50 is adjusted with respect to the focused image 72, 74 to obtain the maximum display amplitude.

摘要： The present disclosure provides a directionally filtered indicator light, wherein a directional filter is applied to a light source that is controlled to emit light when a condition or series of conditions are met. The directional filter, in turn, regulates the transmission of light from the light source so that a first group of individuals, located within a viewing angle, are the only individuals able to see the transmitted light. In one example, the directionally filtered indicator light of the present disclosure allows an indicator light on the interior of a passenger aircraft to be viewed from outside the aircraft in direct sunlight while substantially eliminating the presence of transmitted light from a passenger seating area.
