NAME

InfraRed Camera overview

SYNOPSIS

This is an overview of all the programs used to drive the IR camera. ("A New InfraRed Camera for COAST")

IRCAM

Overall control scripts. ircam_hw_check(1) ensures all hardware is present; ircam_init(1) initialises and calibrates the hardware; ircam_batt_mon(1) monitors the battery status; ircam_temperature(1) measures the dewar temperature; ircam_plcc84(1) and ircam_serial_illuminate(1) control test-hardware; ircam_inspect_focus(1) assists in focusing the optics.

PULSEBLASTER

The PulseBlaster is a 24-channel fast digital timing card, made by spincore. It can be programmed with its own VLIW language, and then triggered either internally in software, or externally from hardware. There is also a kernel driver, some utilities (pb_utils), and a a parser (pb_parse). For more information, see pulseblaster(1).

NI4462

The NI4462 is the ADC for data-capture. See: ni4462_test(1), ni4462_characterise(1).

ARDUINO

There is an Arduino controlling a fast FIFO to make a delay-line for the NI 4462 trigger. See arduino_delay(1).

FTDI245IO

This is an 8-byte parallel port, using an FTDI 245 module in 'bitbang' mode. See ftdi245io(1).

FILTERCTL

The dewar contains a filterwheel with various filters. These can be selected/checked via a stepper motor, and some light gates. It also allows the dewar battery voltage to be monitored, and to set the clock-division on the HW trigger for the pulseblaster. See: filterctl.

CAM2TIFF

The output data files are raw binary files. Convert them (losslessly) to a TIFF file. Find the beam positions. See cam2tiff(1), beamfinder(1), gencamtest(1), getpixel(1), cam2dat(1)

HAWAIISIM

The hawaii-simulator can verify pulseblaster programs, and simulate the physical hardware (PulseBlaster + Hawaii + Optics + ADC). See: hawaiisim(1), cam2tiff(1), pbsim(5)

HAWAIISENSOR

The hawaii-sensor section is for testing and characterisign the actual chip. See: hawaii_characterise(1).

MATHS

Some mathematical tools. fftplot(1) processes a datafile and plots its frequency spectrum. linregplot(1) performs linear regression and plots the data. dat2wav(1) converts to a .wav file for viewing/listening to noise. genffttest(1) and genlinregtest(1) generate some dummy data.

DOCUMENTATION

All commands may be invoked with -h (or --help) to print their detailed usage.
