Systems and methods for measuring spectra and other optical characteristics such as colors, translucence, gloss, and other characteristics of objects and materials such as skin. Instruments and methods for measuring spectra and other optical characteristics of skin or other translucent or opaque objects utilize an abridged spectrophotometer and improved calibration/normalization methods. Improved linearization methods also are provided, as are improved classifier-based algorithms. User control is provided via a graphical user interface. Product or product formulations to match the measured skin or other object or to transform the skin or other object are provided to lighten, darken, make more uniform and the like.

An improved light to frequency converter optical sensor and method using electronic bias. Adjustable gain also may be provided. A summing circuit sums electrical current from a photo detector and electrical current from a bias current circuit and provides the summed current to an integrator. A threshold detector comparator circuit has an input coupled to the output of the integrator and an output providing a series of pulses. The series of pulses has a frequency based on the light received by the photo detector and the electrical current from the bias current circuit.

A method for determining color information of an object, wherein data is generated of the object with an image generation device having a field of view. The object and a reference implement having one or more regions of predetermined optical properties are positioned in the field of view. Data is generated of the reference implement, which includes a positional location attribute, based on which a position of the one or more regions of predetermined optical properties is determined by a processing system without operator identification of the position of the reference implement in the field of view. Color information of the object is generated by adjusting the data generated of the object based on the data generated of the reference implement. The color information may include value, chroma and hue information, RGB values, XYZ coordinates, or Lab values, and may be transmitted electronically to a remote location.

Miniaturized system and method for measuring optical characteristics

Color measuring systems and methods are disclosed. Perimeter receiver fiber optics are spaced apart from a central source fiber optic and receive light reflected from the surface of the object being measured. Light from the perimeter fiber optics pass to a variety of filters. The system utilizes the perimeter receiver fiber optics to determine information regarding the height and angle of the probe with respect to the object being measured. Under processor control, the color measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence and/or surface texture data also may be obtained. Audio feedback may be provided to guide operator use of the system. The probe may have a removable or shielded tip for contamination prevention.

System and method for calibrating optical characteristics

Methods in a spectral measurement apparatus are disclosed. Light is received with a plurality of sensors. Each sensor generates an output signal having a frequency proportional to an intensity of light received by the sensor. First, second and third signals are generated each having a frequency proportional to an intensity of light received by a sensor of a wavelength or spectral band. A spectral characteristic of the received light is determined based on at least the first, second and third signals, which are are coupled to a processing element and input in parallel. The spectral characteristic is determined based on measuring a frequency or period of the at least first, second and third signals. Spectral data based on the determined spectral characteristic is generated by the processing element and displayed on a display device for perception by a viewer or transmitted to a data interface for transmission to an electronic device external to the spectral measurement apparatus.
