Abstract: An optical measuring device is configured to measure a light beam emitted from a light source. The optical measuring device includes a light collecting element, at least four light-sensing elements, a light splitting device, and at least one lens. The light collecting element is configured to collect the light beam. The light-sensing elements are configured to respectively sense the light fields of different light paths of the light beam. The respective distances of the light paths between the respective light-sensing elements and the light source are different from each other. The light splitting device is configured to split the light beam passing through the light collecting element and respectively guide the split light beams to the light sensing elements. The lens is disposed between at least one of the light-sensing elements and the light collecting element, and is configured to form images on the at least four light-sensing elements.
