Infrared camera utilities

Introduction

These are some utilities written to control my Infrared Camera system. They are here just for the online documentation of that system.

The ircam_* utilities are very specific to this hardware; the other programs that we wrote (notably the PulseBlaster, QuickUSB, Arduino and NI4462 utilities) are distributed separately
[There may be a little wider utility in ircam_serial_illuminate.c and cy7sd7_volt2temp.c.]

Contents

• ircam_serial_illuminate.c  -  illuminate the IRcamera with either a LED board or a torch. [This uses the RTS and DTR lines of a [USB] RS-232 serial-port to control 2 external devices.]
• cy7sd7_volt2temp.c  -  Convert the voltage of a Cryogenic CY7SD7 temperature-sensor into Kelvin. [A lookup table with interpolation.]
• ircam_temperature.sh  -  Measure temperature inside the dewar. [A simple script, specific to our hardware only, wraps cy7sd7_volt2temp.]
• ircam_init.sh  -  initialise all sub-systems to a known, sensible state. [An automated "pre-flight checklist" for ensuring a standard starting state of experiments.]
• ircam_batt_mon.sh  -  run in the background, constantly poll that the battery state is good. [A simple script, specific to our hardware only.]
• ircam_plcc84.sh  -  control a dummy dewar chip: useful for aligning optics. [A simple script, specific to our hardware only.]
• ircam_hw_check.sh  -  simple check that all the hardware is connected. [a trivial script.]
• ircam_inspect_focus.sh  -  quick hack: observe the underside of the dewar with a webcam. [a trivial script.]

Installation

• To install, simply: make && sudo make install.

This was originally written as part of my PhD Infrared Camera system.
