Abstract
The present invention is a biological information detection device including: a laser oscillator that oscillates a pulsed laser beam oscillated at a suitable wavelength associated with a measuring target substance; an irradiation mechanism that emits the pulsed laser beam to a liquid biological object inside which the measuring target substance exists; a light receiving sensor that receives a detected laser beam output from the liquid biological object; and a control unit that controls operations of respective components. The control unit outputs an oscillation instruction to the laser oscillator so as to oscillate the pulsed laser beam at a constant cycle, cuts out a detected signal received from the light receiving sensor as time segment data for a time period corresponding to the constant cycle, and calculates a quantity of the measuring target substance in the liquid biological object based on the time segment data.
