Abstract
A detection apparatus and method for detecting the direction to a light source. The detection apparatus comprises a strobe lamp for emitting a high intensity beam of light and a region-based detector, e.g., a quadrant light detector, for receiving a portion of the high intensity beam of light. In employing a strobe lamp, the overall accuracy and range of the detection apparatus are improved.
Claims20
A detection apparatus comprising:
- a strobe lamp for emitting a high intensity beam of light, where said high intensity beam of light is reflected from a target;
- and
- a region-based detector for receiving a portion of said reflected high intensity beam of light.
A detection method comprising the steps of:
- (a) using a strobe lamp for emitting a high intensity beam of light, where said high intensity beam of light is reflected from a target;
- and
- (b) using a region-based detector for receiving a portion of said reflected high intensity beam of light.
