Abstract : An Optical Detection System (ODS) computer code has been developed for the simulation of an electro-optical sensor. The primary emphasis has been devoted to modeling the temporal response of the system to an arbitrary time varying input signal. Input signals comprised of several wavelengths also can be treated. The ODS code consists of the following modules: SOURCE MODULE permits the selection of a number of standard input signals (or the user's signal) as well as white noise and 1/f noise, OPTICS MODULE includes a wide range of optical materials and transmissivities as a function of wavelength as well as an etalon option. MODULATOR MODULE which enables the user to select a chopper, circular variable filter, a Fourier transform spectroscopy, DETECTOR MODULE provides a range of detector materials including wavelength response and temporal response characteristic, PREAMP/AMPLIFIER MODULES enable the user to select a low pass filter, high pass filter, band pass filter, band rejection filter and a set of amplifiers the characteristics of which are expressed in poles and zeroes. The user also may supply his own amplifier characteristics either in terms of poles and zeroes or in the form of a gain curve. In addition to the standard sensor type modules the ODS code includes many utility modules such as PLOT, FFT, EDIT and CONVOLUTION.
