Are camera, projector, and camera–projector calibrations different?
Applied Optics, 2023Structured light projection systems have become a referent in three-dimensional optical metrology. Calibration of the cameras and projectors of these systems is one of the most critical procedures to achieve high-accuracy measurements. However, the calibration process requires some clarifications for adequate experimental implementation.

The superposition of acoustical modes radiated from a transducer can provide directionality from a compact projector. This paper presents the foundation, as well as examples, of piezoelectric ceramic, piezoelectric single crystal, and magnetostrictive versions of this “modal projector.” Measured and analytical, as well as finite element analysis ...

Abstract This chapter includes activities using the projector, a standard tool found in most classrooms that has more possibilities beyond first glance. The projector can bring students together to sing holiday classics, to connect with users from across the globe to share music and cultures, or even to create unique backgrounds for ...

A honeycomb-like shell is provided for an acoustic projector used in sonar applications to increase the bandwidth of the projector, reduce its weight, and to provide increased power density and reduced shell costs. The shell has outer and inner layers, with the honeycomb structure therebetween.

First working prototypes of mobile phones with integrated pico projectors have already been demonstrated and it is expected that such projector phones will be sold within the next three years. Applications that require interaction with large amounts of information will benefit from the large projection and its high resolution.

The sun is the most universal, powerful and familiar energy available on the planet. Every organism and plant has evolved over the years, corresponding to the energy brought by the sun. Humanity is no exception. We have invented many artificial lights since Edison invented light bulbs.

<div class="htmlview paragraph">Future AFS regulation will allow change of the low beam light distribution pattern. In order to propose AFS functions inside the headlamp, several approaches can be taken: combining multisource reflectors, or changing shields within a projector system.
