Unified Pulsed Laser Range Finder and Velocimeter using Ultra-Fast Time-To-Digital Converter
In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...
متن کاملPrepubertal height velocity references over a wide age range.
In order to correct height velocities for the confounders age and sex, SD scores can be calculated using the mean and the SD of the height velocity in the normal population. However, current methods are inappropriate for prepubertal children in the age range in which puberty occurs, because reference groups then consist of a mixed prepubertal/pubertal population. The mathematical infancy-childh...
متن کاملSwitching Converters with Wide DC Conversion Range
In dc-to-dc conversion applications that require a large range of input andlor output voltages, conventional PWM converter topologies must operate at extremely low duty ratios, which limits the operation to lower switching frequencies because of the minimum ONtime of the transistor switch. This is eliminated in a new class of singletransistor PWM converters featuring voltage conversion ratios w...

متن کاملA high-speed wide dynamic range time-to-digital converter
We describe a time-to-digital converter able to measure intervals as great as 100 ns with a resolution of 4 ps rms. It achieves this large dynamic range by simultaneously sampling four sinusoidal wave forms (sine and cosine waves at 200 and 6.25 MHz) derived from a single quartz oscillator. Twelve-bit analog-to-digital conversion of the 200 MHz waves yields the high time resolution. Eight-bit c...
