Title:
SCANNING ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2018/011986
Kind Code:
A1
Abstract:
For the purpose of acquiring an image having good image quality even when deterioration of a laser light source causes a reduction in the amount of light, a scanning endoscope (1) according to the present invention is equipped with: a laser light source unit (10); a current control unit (12) that controls a drive current for the laser light source unit (10); an optical fiber (5) that guides the laser light output from the laser light source unit (10); a scanner (6) that vibrates an emission end (5a) of the optical fiber (5) and two-dimensionally scans the laser light emitted from the emission end (5a); a light amount detection unit (11) that detects the amount of laser light output from the laser light source unit (10); and a characteristic generation unit (17) that generates light-amount-and-current characteristics in which are associated the amount of laser light detected by the light amount detection unit (11) and the drive current input into the laser light source unit (10) by the current control unit (12), said current control unit (12) controlling the driving current on the basis of the light-amount-and-current characteristics generated by the characteristic generation unit (17) so that the target light amount is emitted.
