analog line scan camera www.perkinelmer.com/opto input signals the lc3000 camera requires a single dc supply (+12 to 24vdc) for operation. an internal oscillator sets the default data output rate to default model rate (10 or 20 mhz), and the camera will operate at the maximum line rate. the camera can be further controlled by three externally generated differential input signals: master clock (mclk), line transfer (lt), and line reset (lr). the master clock input determines the data rate frequency for values up to maximum clock of the camera. the mclk input is optional, as the camera is preset to run off of the internal oscil- lator at the default maximum data rate. should a data rate slower than that default rate be necessary, an externally supplied master clock can be enabled by selecting that setting through the bank of dip-switches. the data rate may be run from 20 khz to cameras maximum clock rate. external line transfer operation also can be enabled on the dip-switch bank. the line transfer input signal transfers the charge from each photo site to the readout registers. the readout registers, in turn, transport the charge from each photodiode in succession to the video outputs. the lt input from the user must remain in the on state for at least two mclk cycles to initiate the inter- nal line transfer and may remain on until 2 clock cycles prior to the next desired line transfer. because there are extra stages in the ccd sensors readout register, a minimum number of mclk cycles (the number of elements on the ccd sensor plus 41) must exist between successive lt commands. the maximum line scan period with- out exposure control is 20 millisec- onds. integration times longer than 20 ms can introduce higher levels of dark current, which reduces the dynamic range of the sensor. longer integration times are possible, however, if the cam- era is cooled, which reduces dark cur- rent. specific application characteris- tics, such as light level and rate of object motion, will determine the optimum setting. exposure time of the camera can be separately controlled by using the external line reset input. the lr input is active low (on) in polarity and therefore, when not in use, must be held high (off). in this condition, the exposure time is defined by the period of the lt signal. when using the lr input signal, the exposure period is defined to be the time between the rising edge of lr to the rising edge of lt. the lr signal must be held active low (on) for a minimum of 4 clock cycles and must be inactive high (off) for a minimum of 4 clock cycles prior to the lt signal. output signals the lc3000-series camera provides three output synchronization signals: camera clock (cclk), line enable (len), and camera line transfer (clt). the camera clock (cclk) operates at either the mclk frequency or default camera frequency, and is synchro- nized to the analog video. the output of the cclk signal can be used to cap- ture analog video data by a frame grab- ber or digitizer. the line enable (len) signal brackets the valid analog video. the signal becomes high one cclk period before the first valid pixel and goes low one cclk period before the last valid pixel. the video output is a contiguous pixel data stream with a dynamic range (defined as peak video divided by rms. pixel noise) of greater than 500:1. the camera line transfer (clt) out- put signal is an internally generated sync signal. its falling edge indicates the start of a line readout sequence. this signal may be used for control- ling strobes, shutters or other acces- sories of the users system. dsp-201.01 d - 4 /200 2 page 5 gain times range dip switch #3 dip switch #4 dip switch #5 full scale 0 on on on 0.67 1 on on off 1.00 2 on off on 1.50 3 on off off 2.20 4 off on on 3.35 5 off on off 5.00 6 off off on 7.50 7 off off off 11.20 table 3. video gain switch settings range dip switch #6 dip switch #7 dip switch #8 normal offset (mv) 0on on on 0 1 on on off 6.4 2 on off on 12.8 3 on off off 19.3 4 off on on 25.7 5 off on off 32.1 6 off off on 38.6 7 off off off 45.0 table 2. video offset switch settings 12586 final art 2 5/9/01 4:51 pm page 5
