    Abstract: An imaging system controller (5) outputs a control signal (VC). The control signal (VC) gives a command to output driving clocks (φVn, φHm) of an imaging element (1) in a signal transmission period, and a command to suspend output of the clocks (φVn, φHm) in an idle period subsequent to the signal transmission period. The length of the idle period is a multiple of the length of the signal transmission period by a natural number. The imaging system controller (5) periodically repeats output of the control signal (VC) giving these commands a number of times corresponding to the number of horizontal lines of the imaging element (1). In response to the commands of the control signal (VC), a timing generator (2) generates and outputs the clocks (φVn, φHm), and suspends generation and output of the same. An imaging device (10) thereby intermittently drives the imaging element (1), to generate and output a picked-up image signal (V2).

    Abstract: An apparatus for continuously measuring the concentration of particulates in a sample gas by using an optoacoustic effect. Identical laser rays are directed along two optical paths, and a chopper and an optoacoustic cell are position in the recited order in each of the optical paths. Sample gas containing particulates is introduced into one optoacoustic cell and sample gas from which the particulates have been removed is introduced into the other optoacoustic cell. The respective choppers are driven for producing a chopping action on the respective laser rays at a frequency corresponding to the resonant frequency of the corresponding optoacoustic cells, and the outputs from the cells can be compared for providing an indication of the concentration of the particulates in the sample gas.
