Publication number: 20080246942Abstract: A laser radar sensor includes a photoreceptor, a dummy circuit, an amplifier, a selector, and the first and the second detection circuits. A photoreception signal outputted from the photoreceptor and an output signal of the dummy circuit are amplified by the amplifier, and inputted to the second detection circuit. A noise component included in the photoreception signal based on the output signal of the dummy circuit when distance detection is not performed. The distance detection is performed based on the reception signal from which the noise component is removed. As a result, a reduction in detectable distance of the laser radar sensor is less likely to occur. Furthermore, the noise component is detected using the dummy circuit and the selector. Thus, the consideration of the predetermined rotation angle is not required in optical system design and limiting factors in the optical system design can be reduced.Type: ApplicationFiled: January 24, 2008Publication date: October 9, 2008Inventor: Yoshiaki Hoashi

Publication number: 20080246943Abstract: A 3D pulsed laser projection system scans an object to produce a dense 3D point cloud and projects a laser light beam onto an object as a glowing template. A high-sensitivity optical feedback system receives and detects a feedback beam of the output beam light diffusely reflected from the object. The feedback light and projected beam share the same beam path between steering mirrors and the object. A light suppression component controls stray scattered light, including ambient light, from being detected. A time-of-flight measurement subsystem provides a distance-to-object measurement for projected pulses. An acousto-optical modulator, variable gain detected signal amplification and variable photo-detector power together produce a dynamic range for detected reflected feedback signals of at least 100,000, and up to 500,000. Optical fiber cables spatially filter scattered light and isolate the photo-detectors thermally.Type: ApplicationFiled: December 11, 2007Publication date: October 9, 2008Applicant: Laser Projection Technologies, Inc.Inventors: Steven P.
