A method for detecting and acquiring light from a light source using an array of movable light sensors (36, 37, 38) disposed on a carrier platform coupled to and movable by plural actuators each associated with a respective light sensor, the method being characterized by: assigning a threshold value to the light emitted by the light source representing a predetermined light detection level of the emitted light; determining a standard deviation value of the measured level of light intensity received by the movable light sensors from the light source, wherein the standard deviation value is calculated based on the measured levels of light intensity received from each of the plurality of light sensors at a single point in time; moving the array in the direction of the light source while comparing the standard deviation value of the light intensity with the assigned standard deviation threshold value of the light emitted by the light source until the standard deviation value is less than said threshold value, whereupon said light of the light source is acquired by the light sensors, wherein the light sensors are moved in a stepwise, incremental manner in the direction of the light source by either moving an actuator (9, 10, 11) associated with a respective light sensor in a first direction if the light received by that sensor is greater than the average level of light intensity received by all of the light sensors or moving an actuator associated with a respective light sensor in a second direction if the light received by that sensor is less than the average level of light intensity received by all of the light sensors, wherein the first direction is opposite of the second direction, and wherein the number of steps is limited to a predetermined number, with the standard deviation value of the measured level of light received from the light source again determined if the standard deviation value is not less than the threshold value within said predetermined number of steps; determining an updated standard deviation for comparison with the assigned threshold value of the light source until the updated standard deviation is less than said threshold value of the light emitted by the source; and tracking the light source if the standard deviation value is less than the threshold value within the predetermined number of steps of movement of the array of light sensors. assigning a threshold value to the light emitted by the light source representing a predetermined light detection level of the emitted light; determining a standard deviation value of the measured level of light intensity received by the movable light sensors from the light source, wherein the standard deviation value is calculated based on the measured levels of light intensity received from each of the plurality of light sensors at a single point in time; moving the array in the direction of the light source while comparing the standard deviation value of the light intensity with the assigned standard deviation threshold value of the light emitted by the light source until the standard deviation value is less than said threshold value, whereupon said light of the light source is acquired by the light sensors, wherein the light sensors are moved in a stepwise, incremental manner in the direction of the light source by either moving an actuator (9, 10, 11) associated with a respective light sensor in a first direction if the light received by that sensor is greater than the average level of light intensity received by all of the light sensors or moving an actuator associated with a respective light sensor in a second direction if the light received by that sensor is less than the average level of light intensity received by all of the light sensors, wherein the first direction is opposite of the second direction, and wherein the number of steps is limited to a predetermined number, with the standard deviation value of the measured level of light received from the light source again determined if the standard deviation value is not less than the threshold value within said predetermined number of steps; determining an updated standard deviation for comparison with the assigned threshold value of the light source until the updated standard deviation is less than said threshold value of the light emitted by the source; and tracking the light source if the standard deviation value is less than the threshold value within the predetermined number of steps of movement of the array of light sensors.
