Abstract: A photoacoustic apparatus includes a laser light irradiating unit that irradiates an inside of a subject with pulsed light; a photoacoustic signal acquiring unit that acquires a photoacoustic signal from a photoacoustic wave from the subject; a light amount detecting unit that detects a light amount of the pulsed light; a correlation data memory that stores first correlation data and second correlation data; an energy estimating unit that estimates an energy on the basis of the amount of the pulsed light and the first correlation data; a pulse width estimating unit that estimates a pulse width on the basis of the estimated energy and the second correlation data; and a photoacoustic signal correcting unit that corrects the photoacoustic signal on the basis of a first difference between the estimated energy and a reference energy and a second difference between the estimated pulse width and a reference pulse width.

Abstract: A Q switch is vibrated by applying a first voltage, and pulsed laser light is emitted by applying a second voltage to the Q switch at a point in time at which a preset delay time has passed from the start of emission of excitation light. Then, in this case, a time which is within a period, for which the vibration of the Q switch continues, and at which the intensity of the pulsed laser light periodically changing due to the vibration of the Q switch is maximized in a case where a point in time of application of the second voltage to the Q switch is changed is set as the delay time.

Abstract: In each of a first phase shift differential image produced in the absence of a subject in preliminary imaging and a second phase shift differential image produced in the presence of the subject in main imaging, boundaries, at each of which a value changes from π/2 to −π/2 or from −π/2 to π/2, are determined. First and second staircase data in each of which a value changes by π or −π when crossing each of the boundaries in a predetermined direction is produced. The first and second staircase data is added to the first and second phase shift differential images to produce first and second added phase shift differential image, respectively. The first added phase shift differential image is subtracted from the second added phase shift differential image to produce a corrected phase shift differential image.
Abstract translation: 在初步成像中不存在被摄体的情况下产生的第一相移差分图像和在主成像中存在被摄体的情况下产生的第二相移差分图像中的每一个中，每个图像中的值从pi / 2变化 到-pi / 2或从-pi / 2到pi / 2。 产生了当在预定方向上跨越每个边界时，值或-pi改变值的第一和第二阶梯数据。 将第一和第二阶梯数据添加到第一和第二相移差分图像中，以分别产生第一和第二相移相差分图像。 从第二加相移差分图像中减去第一加相移差分图像，以产生校正的相移差分图像。
