The requested instrument is a unique optical profilometer that can make very accurate measurements of, and visualize in 3D, the shape and texture of engineered surfaces. It is the only such instrument on the market that can perform such measurements using three different technologies (confocal, interferometry, and focus variation), each with their advantages and disadvantages. In contrast to other profilometers that allow measurements on a limited set of surfaces, the 3-in-1 integration of these measurement principles means that measurements can be made on a very wide variety of smooth and rough surfaces that have a wide variety of slopes. ******The profilometer, only the second of its kind in Ontario, is urgently needed to support the research programs of eight world-class investigators at three institutions in the greater Toronto area (Ryerson University, University of Toronto, and York University). The equipment will support research that impacts a wide variety of industries including health care, microtechnology, aerospace, automotive, food, protective clothing, and power generation. It includes development of new: (i) bioanalytic chips to diagnose and treat diseases; (ii) micro-sensors and actuators for autofocus and optical image stabilization in miniature cameras; (iii) coatings used to protect wind turbine blades and other components from the impact of air-borne particulates; (iv) lightweight metals for use in aerospace and automotive applications; (v) engineered tissues such as lab-grown cartilage for use in artificial joint replacement; (vi) protective clothing for military and laboratory safety applications; and (vii) methods to manufacture and store chocolate so that it lasts longer and is of highest quality. ******These new advances in such a wide variety of applications will ensure that Canadian industry is put at an advantage, generating new jobs and bringing significant health and economic benefits to Canadian society. The students working on these projects under the supervision of the researchers will be amongst the very few to be trained on such a unique instrument and will thus be at an advantage when they seek employment or pursue higher graduate studies upon graduation.

所要求的仪器是一种独特的光学轮廓仪，可以非常精确地测量工程表面的形状和纹理，并以3D方式进行可视化。它是市场上唯一可以使用三种不同技术（共焦、干涉和聚焦变化）进行此类测量的仪器，每种技术都有其优点和缺点。与允许在有限表面上进行测量的其他轮廓仪相比，这些测量原理的三合一集成意味着可以在具有各种斜率的各种光滑和粗糙表面上进行测量。** 轮廓仪是安大略同类产品中的第二台，迫切需要它来支持大多伦多地区三个机构（瑞尔森大学、多伦多大学和约克大学）的八名世界级研究人员的研究计划。这些设备将支持影响各种行业的研究，包括医疗保健，微技术，航空航天，汽车，食品，防护服和发电。它包括开发新的：㈠诊断和治疗疾病的生物分析芯片; ㈡微型照相机自动对焦和光学图像稳定的微型传感器和致动器; ㈢保护风力涡轮机叶片和其他部件不受空气中微粒影响的涂层; ㈣航空航天和汽车应用中使用的轻金属;（v）工程组织，例如用于人工关节置换的实验室生长的软骨;（vi）用于军事和实验室安全应用的防护服;以及（vii）制造和储存巧克力的方法，以使其持续时间更长并具有最高质量。 ** 这些在如此广泛的应用中取得的新进展将确保加拿大工业处于优势地位，创造新的就业机会，并为加拿大社会带来重大的健康和经济利益。 在研究人员的监督下从事这些项目的学生将是极少数接受这种独特仪器培训的学生之一，因此，当他们毕业后寻求就业或攻读更高的研究生课程时，他们将处于优势地位。
