Abstract

The present invention provides an optical system having an array of light emitting semiconductor devices to performing an operation that have multiple characteristics associated with performing the operation. The array includes at least one detector located within the array to selectively monitor multiple characteristics of the light emitting semiconductor devices and is configured to generate a signal corresponding to the selected characteristic. A controller is configured to control the light emitting semiconductor devices in response to the signal from the at least one detector. At least one of the multiple characteristics may be concentrated at an area of the array and the at least one detector may be located within the array at the area of the array to selectively monitor characteristic that is concentrated at the area of the array.
