Title:
LIGHT SCANNING OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/109814
Kind Code:
A1
Abstract:
This light scanning observation device 10 includes: light sources 33R, 33G, 33B of different colors; a light emitting timing control unit 32; an illumination optical fiber 11 that emits light from the light sources from a distal end onto a subject 100; a drive unit 21 that helically drives the distal end of the illumination optical fiber 11; a light detector 35 that converts light obtained when the subject is irradiated with the light into an electrical signal; and a signal processing unit 37 that generates an image signal on the basis of the electrical signal. The light emitting timing control unit 32 controls the light emitting timings of the light sources 33R, 33G, 33B so that an irradiation density per unit angle in a central region of helical scan is less than an irradiation density per unit angle in a peripheral region thereof and so that an irradiation density of light of at least one color is different from the irradiation densities of light of the other colors .
