PORTABLE NONINVASIVE INSPECTION DEVICE

Abstract

The present invention discloses a portable noninvasive inspection device, which comprises a light source illuminates a target to generate an optical inspection signal; a probe head provides an optical path for said light source to receive said optical inspection signal; at least one switched filter module arranged in the optical path, allowing the optical inspection signal to pass there through to generate a corresponding spectral signal; and an image sensor arranged behind the switched filter module, receiving the spectral signal and generating a spectral image. The spectral image can be transmitted to an external device, wherefrom the user can use the spectral image to examine the target in further detail. The present invention features a rotary-type or movable-type switched filter module, which facilitates the user to switch filters easily during optical inspection and expands the application of the present invention.
