Time-to-Digital Converter

Mouser Electronics, Inc., (Mansfield, TX) is now stocking the TDC7201 time-to-digital converter from Texas Instruments (TI). The TDC7201 is designed for use with ultrasonic, laser, and radar range finding equipment using time-of-flight (TOF) technique. TI’s TDC7201 time-to-digital converter has two built-in time-to-digital converters (TDCs) that can be used to measure distance down to 4 cm and up to several kilometers using a simple architecture. The TDC7201 features a wide measurement range of 0.25 ns to 8 ms and high accuracy of 28 ps. The device has a single shot resolution of 55 ps, (equivalent to 0.825 cm).

Fabricating Optical Mirrors for Use in Outer Space Measurements

There are many ways to manufacture an optic depending on the complexity of the component and the application. From choosing the best substrate, to detailing the numerous operations required to make the optic, all the while considering tight tolerances and other specifications. This article highlights the precision needed to successfully fabricate the mirrors for the Hobby-Eberly Telescope Dark Energy Experiment’s (HETDEX’s) Visible Integral Field Replicable Unit Spectrographs (VIRUS) unit which was designed to measure dark energy in outer space.
