In general, the devices and methods utilize a filter component and photodiode to measure optical power being generated by at least one laser light source, with the filter component configured to at least partially compensate for the non-uniform electric current response of the photodiode. Such a configuration facilitates accurate optical power measurement using only one photodiode, and thus can facilitate accurate optical power measurement in a relatively compact device and with relatively low cost."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices and methods for optical power sensing scanning laser projectors","description":"Devices and methods are described herein to measure optical power in scanning laser projectors.
