“…Only illuminated pixels within the ROI will send information out of chip. The idea of exploiting Address Event Representation (AER) sensors to design sun sensors was already advanced by Farian et al in a conference paper [12]. The architecture of a sun sensor with two asynchronous pixel rows with a L-shape and dedicated optics was presented.…”

“…To start operating, we just need to determine the coordinates (x c , y c ) of the pixel that is illuminated when there is a light beam aligned to the sensor transversal axis (θ = 0 • ). Hence, this an advantage for the test over systems with more complex optics that require a precise alignment before operating [12]. To debug and test the sensor, the jAER interface [17] was adapted to display the information coming from our sensor, as it is depicted in Fig.…”

Abstract-We present a novel sun sensor concept. It is the very first sun sensor built with an Address Event Representation (AER) spiking pixel matrix. Its pixels spike with a frequency proportional to illumination. It offers remarkable advantages over conventional digital sun sensors based on Active Pixel Sensor (APS) pixels. Its output data flow is quite reduced. It is possible to resolve the sun position just receiving one single event operating in Time-to-First-Spike (TFS) mode. It operates with a latency in the order of milliseconds. It has higher dynamic range than APS image sensors (higher than 100dB). A custom algorithm to compute the centroid of the illuminated pixels is presented. Experimental results are provided.
