Abstract From the Canadian patent
Sensor means comprise three cylindrical bodies having sensing windows of constant width for all the bodies, or varying according to an exponential law as a function of the bearing angle in the case of the third body (C1). One of the first two bodies (C2) has a skirt masking part of the window, to make this body responsive to the elevation. The light signals available in the three bodies are carried by optical fibres (L11 to L31) of different lengths to a photodetector (PD) connected by a capacitor (CL) to a logarithmic amplifier (AL) followed by an analog/digital coder (CAN) and processing means (DT). It is then possible to measure the elevation and bearing of an incident laser pulse, its …
