Abstract: Techniques for using a sensor to perform laser signal decoding are disclosed. The sensor may be a global shutter sensor or a rolling shutter sensor. The sensor generates a first set of images while operating in a first mode. In response to detecting a laser signal in the first set of images, the sensor is caused to operate in a second mode. The laser signal includes an embedded frequency signal component and repeats at a periodic rate. While the sensor is operating in the second mode, the sensor generates a second set of images, which capture an entire period of the laser signal. From the second set of images, the embedded frequency signal component is determined. A decoding operation is performed using the embedded frequency signal component.

Abstract: The present disclosure provides a hyperbranched polycaprolactone-polylactic acid copolymer (PCL-PLA), preparation method and solid electrolyte application thereof, and belongs to the technical field of polymer synthesis. The copolymer is prepared as follows: an intermediate of dihydroxymethyl propionamido-terminated polylactic acid (PLA-DMPA) is synthesized with amino-terminated polylactic acid (PLA) and 2,2-dihydroxymethylpropionic acid as starting materials, and then the PLA-DMPA is subjected to polymerization with ?-caprolactone. PCL and PLA are combined through chemical bonds. The polymer with a hyperbranched structure has many free terminal groups, which can provide increased lithium-ion transmission channels and facilitates the increase of ionic conductivity. The presence of PLA reduces the crystallinity of PCL, and is conducive to the movement of chain segments of the polymer, thereby improving the transport capacity of lithium ions in the polymer.

Abstract: Provided is a generation method for a programmable analog fringe pattern with an extended depth of field. A laser emits a laser beam. After focusing and collimation thereof with a collimating lens, a collimated Gaussian laser beam meeting requirements is obtained. The laser beam is reflected by a mirror once, passes through a round diaphragm and is incident on a MEMS scanning mirror. The beam is reflected by the MEMS scanning mirror to the surface of a tested object. The laser is controlled by a sinusoidal current signal generated by a drive board so as to sinusoidally modulate the brightness of the laser beam. The MEMS scanning mirror is stimulated by a drive signal generated by the drive board to turn two-dimensionally, so as to drive the laser beam to perform scanning, thus generating a fringe pattern image.
