Applications for Edge-Emitting Pulsed Laser Diodes often require device operation with narrow pulse widths. These conditions may be necessary for ensuring eye-safe system certification or precision in distance measurement systems. Short pulses also allow for reliable higher peak power operation of the devices. This application note examines the many challenges that occur in generating short pulses with pulsed laser diodes and possible solutions.
Stability Of Silicon Photodiodes For Laser Emission Measurements
Laser emission safety regulations are put in place to necessitate simple instrumentation for user monitoring and regulatory purposes. Instruments must be accurately calibrated and maintain their calibrations over long periods and must be achieved within the optical transducer. This white paper’s objective is to examine the suitability of silicon photodiodes as the transducer, and to discuss the calibration accuracy, reproducibility, and stability that are likely to be achieved from a commercial company.

Why Is Binning Different In CMOS Image Sensors Compared To CCD Image Sensors?
“Binning” is defined as the combination of the charge carrier content of two or more pixels of an image sensor to form a new so-called super pixel. This white paper discusses the reasons for the difference of “binning” in CMOS and CCD technologies and how it improves the signal-to-noise ratio.
