Illumination systems and methods of designing and construction of the same are disclosed. The resulting illumination systems comprising both Front and Back light modules, provides selectable and programmable illumination according to the requirements of the invention for optimal performance of enhancing defects on a multidimensional object. The light guides are suitably aligned to the Backlight module and mechanically integrated with spring loaded mechanisms to enable them to move freely and subsequently re-postion them to a reference home position as determined at the time of setup of the illumination assembly. The Front light module is utilised to highlight surface defects and mechanically integrated to the illumination system. The illumination modules, may include multiple discrete light emitting components of different spatial intensity distribution and color spectrum mounted in specific layout such that the application oriented combined illuminating effect is created.

[Problem] When the inclination of an object surface reaches or exceeds a certain level, direct light consisting of a specularly reflected light component leaves the range of the solid observation angle formed by the observation optical system, and it becomes difficult to continuously and quantitatively obtain the surface shape of the object surface. [Solution] This invention emits emission light capable of, within an observation range for an object under inspection, simultaneously forming the same solid emission angle on each point on an object surface regardless of the distance from the illumination; for a non-continuous area where direct light is not returned, uses variation in the solid angle of direct light unique to the vicinity of the non-continuous area to make it possible to at least measure height-direction variation of the non-continuous area; and uses brightness information indicating variation in a scattered light component of object light from the non-continuous area to make it possible to continuously acquire the three-dimensional shape of the non-continuous area.
