Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, that provide for optical techniques for manufacturing robots, such as for filtering certain reflections when scanning an object. For example, the techniques may include receiving, from a detector, sensor data based on detected light, the detected light including reflections of light projected by one or more emitters and reflected off of an object. The techniques may further include determining, based on the sensor data, a first-order reflection and a second-order reflection. The techniques may also include determining, based on the first-order reflection and a second-order reflection, a difference, the difference includes a polarity difference, an intensity difference, or a combination thereof. The techniques may include filtering the second-order reflection based on the difference Other aspects and features are also claimed and described.
